• Infiniti G35
• Infiniti I30
• Infiniti I35
• Infiniti M35
• Infiniti M45
• Infiniti Q45
• Infiniti Q50
• Infiniti QX56

Compatibility information should always be treated as a general selection guide rather than confirmation that a product will fit every vehicle carrying the same model name.

Before purchasing or installing a speaker, the vehicle’s exact production date, body style, factory speaker configuration, mounting dimensions, connectors, impedance and amplifier arrangement must be confirmed.

This is particularly important where the vehicle has Bose audio.

A Focal speaker may be physically suitable for a selected mounting position but electrically unsuitable for the original Bose amplifier. Similarly, an OEM-style connector does not prove that the replacement speaker has the correct impedance, frequency range or power requirements.

Owners of other Infiniti models may still be able to obtain a customised Focal audio upgrade.

Potential models include:

• Infiniti G35
• Infiniti G37
• Infiniti M35
• Infiniti M35h
• Infiniti M37
• Infiniti M45
• Infiniti Q30
• Infiniti Q45
• Infiniti Q50
• Infiniti Q50 Hybrid

Use the compatibility table and product selection sections on this page to explore potential solutions. Then consult an Authorised Focal Australia Dealer to confirm which products are physically, electrically and acoustically suitable for your exact vehicle.

The purpose of an Infiniti audio upgrade is not simply to make the system louder.

A properly designed Focal system can deliver clearer vocals, stronger mid-bass, improved treble detail, more accurate stereo imaging, deeper bass and cleaner performance at higher listening levels while retaining the vehicle’s premium appearance and essential factory functions.

1. Can an Infiniti factory audio system be upgraded with Focal speakers?

Potentially, yes.

Many Infiniti factory audio systems can be improved with appropriately selected Focal speakers and supporting equipment.

The correct solution depends on:

• Exact Infiniti model
• Production month and year
• Vehicle Identification Number
• Sedan, coupe, convertible or SUV body
• Australian-delivered or imported specification
• Standard or Bose audio system
• Number and location of speakers
• Factory amplifier
• Factory subwoofer
• Speaker impedance
• Available installation depth
• Factory signal processing
• Existing audio modifications
• Desired performance
• Available budget

A relatively straightforward Infiniti system may allow selected factory speakers to be replaced with compatible Focal Inside products such as the IS RNS 165 or IC RNS 165.

A more complex Bose-equipped vehicle may require:

• Signal testing
• Custom mounting adaptors
• Impedance matching
• Bose amplifier integration
• Replacement amplification
• Digital signal processing
• Retention of selected factory speakers
• Centre-channel management
• Subwoofer integration
• Professional tuning

The presence of a Bose badge does not automatically prevent an upgrade. It does mean the system must be investigated before products are selected.

A replacement speaker must be compatible in several ways:

• Physical fitment
• Mounting-hole pattern
• Installation depth
• Factory grille clearance
• Window clearance
• Connector design
• Speaker impedance
• Factory amplifier output
• Frequency range supplied to the speaker
• Existing crossover filtering
• Speaker sensitivity
• Acoustic role within the system

Replacing speakers without checking these factors can cause reduced volume, tonal imbalance, warning sounds that are too loud or quiet, poor bass, amplifier problems or damage to audio equipment.

A successful Infiniti upgrade treats the speakers, amplifier, source signal, mounting system and vehicle acoustics as one complete system.

2. Is there a Plug & Play Focal speaker kit for Infiniti vehicles?

Focal offers potential vehicle-specific solutions for selected Infiniti applications, including the IS RNS 165 component kit and IC RNS 165 coaxial kit.

These products use vehicle-specific mounting and connection features for selected Renault, Nissan, Infiniti and Smart applications.

However, they should not be represented as universally Plug & Play across the entire Infiniti range.

Compatibility can vary according to:

• Model generation
• Production date
• Body style
• Market specification
• Speaker position
• Standard or Bose audio
• Factory amplifier
• Factory speaker impedance
• Connector variation
• Speaker mounting depth
• Previous modifications

A product may be Plug & Play in one speaker position but unsuitable for another position in the same vehicle.

For example, an Infiniti may use different speakers for:

• Front-door woofer
• Front tweeter
• Dashboard midrange
• Centre channel
• Rear door
• Rear shelf
• Surround channel
• Factory subwoofer

A speaker should not be described as Plug & Play merely because its electrical connector can be attached to the factory wiring.

Proper Plug & Play compatibility should include:

• Correct physical mounting
• Correct connector
• Correct polarity
• Appropriate impedance
• Suitable factory power
• Correct frequency range
• Retention of the factory grille
• No interference with the window
• No interference with airbags
• No permanent vehicle modification
• Correct operation of factory functions

Where a genuine direct-fit solution is not available, an Authorised Focal Australia Dealer may be able to create an OEM-style customised installation using suitable adaptors and wiring.

This may preserve:

• Original speaker locations
• Factory grilles
• Door trims
• Dashboard appearance
• Original head unit
• Infiniti InTouch
• Steering-wheel controls
• Around View Monitor
• Factory cameras
• Navigation
• Bluetooth
• Apple CarPlay
• Android Auto

The exact installation method should be confirmed before the system is described as fully reversible or modification-free.

3. Which Infiniti models may be suitable for a Focal audio upgrade?

A Focal audio upgrade may be possible in a wide variety of Infiniti vehicles.

Potential sedan, coupe and convertible applications include:

• Infiniti I30
• Infiniti I35
• Infiniti G35
• Infiniti G37
• Infiniti Q45
• Infiniti M35
• Infiniti M35h
• Infiniti M37
• Infiniti M45
• Infiniti Q50
• Infiniti Q50 Hybrid
• Infiniti Q60
• Infiniti Q70
• Infiniti Q70 Hybrid

Potential crossover and SUV applications include:

• Infiniti EX35
• Infiniti EX37
• Infiniti FX35
• Infiniti FX37
• Infiniti FX45
• Infiniti FX50
• Infiniti QX30
• Infiniti QX50
• Infiniti QX55
• Infiniti QX56
• Infiniti QX60
• Infiniti QX70
• Infiniti QX80

This model list does not confirm compatibility with a particular Focal speaker.

Infiniti model names have changed over time. For example:

• Selected G models were subsequently represented within the Q naming structure
• Selected M models became part of the Q70 range
• The EX became associated with the QX50 name
• The FX became associated with the QX70 name
• The QX56 was succeeded by the QX80 name

A change in model name does not prove that the speaker layout remained identical.

Infiniti vehicles can also share selected architecture and components with Nissan, Renault or Mercedes-Benz vehicles.

Examples include:

• Infiniti’s broader relationship with Nissan
• QX56 and QX80 connections with Nissan or Armada-based platforms
• Q30 and QX30 platform relationships with selected Mercedes-Benz vehicles
• Shared engines, transmissions or electrical components across alliances

These relationships do not establish audio compatibility.

A Nissan, Renault or Mercedes-Benz speaker kit should not be assumed to fit an Infiniti solely because the vehicles share a platform, engine or other component.

The installer must confirm:

• Exact chassis or model code
• Production date
• Country of origin
• Speaker mounting dimensions
• Factory connectors
• Speaker impedance
• Factory amplifier
• Signal processing
• Available installation space

Imported vehicles may differ from Australian-delivered examples even when they carry the same exterior model name.

4. What is the difference between standard and Bose Infiniti audio systems?

A standard Infiniti audio system may use fewer speakers and a less complex amplification arrangement.

Depending on the vehicle, a standard system may have:

• Four speakers
• Six speakers
• Conventional door speakers
• Separate front tweeters
• Head-unit-powered speakers
• Basic equalisation
• No separate subwoofer

A Bose-equipped Infiniti may use:

• Dedicated Bose amplifier
• Low-impedance speakers
• Centre-channel speaker
• Dashboard midrange speakers
• Multiple tweeters
• Door woofers
• Rear surround speakers
• Rear-shelf speakers
• Factory subwoofer
• Bose Centerpoint
• Bose AudioPilot
• Driver’s Audio Stage
• Speed-sensitive volume
• Active filtering
• Channel-specific equalisation
• Signal delay

The configuration varies by model and specification.

For example, selected Infiniti systems have included:

• Six-speaker standard audio
• 13-speaker Bose audio
• 16-speaker Bose Performance Series audio
• 17-speaker Bose Performance Series audio
• Bose Studio Surround
• Bose systems with multiple woofers or subwoofers

The number of speaker grilles does not always equal the number of audio channels. Some grilles may contain more than one driver, while some speakers may reproduce only a restricted frequency range.

A Bose amplifier may send:

• Bass only to a door woofer
• Midrange only to a dashboard speaker
• Treble only to a tweeter
• Summed information to a centre speaker
• Processed ambience to a surround speaker
• Low-frequency information to a subwoofer

Replacing one of these speakers with a general full-range speaker does not restore frequencies that are absent from the factory channel.

The installer should measure:

• Speaker impedance
• DC resistance
• Signal voltage
• Frequency response
• Crossover filtering
• Equalisation
• Polarity
• Signal delay
• Volume-dependent processing
• Bose mode behaviour

Bose-equipped vehicles often benefit from a carefully planned amplifier and DSP solution rather than an isolated speaker replacement.

5. Can a faulty, broken or not-working Infiniti speaker be replaced with a Focal speaker?

Potentially, yes, but the original fault should be diagnosed first.

Common symptoms include:

• No sound from one speaker
• Distorted sound
• Buzzing
• Rattling
• Crackling
• Weak bass
• Intermittent output
• Uneven left-to-right volume
• Sound that cuts out over bumps
• Distortion at particular volume levels

These symptoms do not always indicate a failed speaker.

Possible causes include:

• Damaged speaker cone
• Failed voice coil
• Deteriorated suspension
• Water contamination
• Loose mounting hardware
• Damaged wiring
• Corroded connector
• Faulty Bose amplifier channel
• Faulty head-unit output
• Incorrect balance or fade settings
• Previous aftermarket wiring
• Debris behind the trim
• Loose door or dashboard components
• Infotainment software issue

The dealer should test:

• Speaker resistance
• Wiring continuity
• Connector condition
• Signal from the source or amplifier
• Signal polarity
• Frequency content
• Speaker mounting
• Moisture exposure
• Left-to-right output
• Bose amplifier operation

If the factory speaker has failed, a compatible Focal replacement may provide an opportunity to improve sound quality rather than installing another basic factory speaker.

It may be advisable to replace speakers in matched pairs.

Replacing only one side can produce differences in:

• Sensitivity
• Output level
• Impedance
• Tonal balance
• Treble response
• Bass response
• Stereo imaging
• Power handling

In a Bose system, the failed speaker’s impedance and acoustic role must be confirmed before a replacement is chosen.

A conventional 4-ohm speaker may produce substantially less output when used in place of a low-impedance Bose speaker. Installing a lower-impedance replacement can also overload an amplifier that was not designed for it.

Owners should check applicable vehicle and component coverage before modifying a vehicle that may still have warranty protection.

Focal Australia’s Authorised Dealer Network can diagnose the fault, confirm product compatibility and complete the installation professionally.

6. Can the Infiniti Q50, Q60 or Q70 audio system be upgraded?

Potentially, yes.

The Q50, Q60 and Q70 can contain sophisticated factory audio and infotainment systems, particularly when Bose equipment is fitted.

Possible upgrades include:

• Front-door woofers
• Front tweeters
• Dashboard speakers
• Centre-channel speaker
• Rear-door speakers
• Rear-shelf speakers
• Additional amplification
• Digital signal processing
• Factory-subwoofer integration
• Additional subwoofer
• Focal BAM treatment
• Professional tuning

The Q50 and Q60 may have different audio systems depending on:

• Production year
• Equipment grade
• Standard or Bose audio
• Sedan or coupe body
• Petrol or hybrid powertrain
• Country of origin
• Infiniti InTouch generation
• Previous modifications

Selected Q60 vehicles have used a six-speaker standard system or a 13-speaker Bose system. These configurations should not be treated as interchangeable.

The Q70 may use Bose Studio Surround and a more complex multi-speaker arrangement.

The installer should confirm:

• Speaker count
• Factory amplifier location
• Factory subwoofer
• Centre channel
• Dashboard speaker arrangement
• Door-speaker impedance
• Rear-speaker configuration
• Available full-range signal
• AudioPilot or Centerpoint functions
• Hybrid powertrain where applicable

A Q50, Q60 or Q70 upgrade may retain the original Infiniti InTouch system and use a compatible amplifier or DSP downstream from the factory source.

The objective should be to improve performance without affecting:

• Upper and lower displays
• Navigation
• Climate-control display
• Around View Monitor
• Reversing camera
• Parking sensors
• Steering-wheel controls
• Telephone calls
• Voice control
• Factory warning sounds

Replacing the factory head unit is generally more complicated than replacing or integrating downstream audio components because the factory display can manage multiple vehicle functions.

7. Can an Infiniti G35, G37, M35, M37 or M45 be upgraded?

Potentially, yes.

These older Infiniti vehicles may provide good opportunities for speaker replacement, acoustic treatment and modern amplification.

Potential upgrades include:

• Focal IS RNS 165 front component speakers where confirmed
• Focal IC RNS 165 coaxial speakers where confirmed
• Custom Focal component speakers
• Rear-speaker replacement
• Custom mounting adaptors
• Factory connector adaptation
• Additional amplification
• Digital signal processing
• Subwoofer integration
• Focal BAM treatment

Many G and M Series vehicles were equipped with Bose audio.

The Bose system may include:

• Dedicated amplifier
• Low-impedance door speakers
• Dashboard or centre speaker
• Rear-shelf speakers
• Factory woofer
• Channel-specific filtering
• Proprietary connectors

An older vehicle may also have previous modifications that are not immediately visible.

These may include:

• Aftermarket head unit
• Previously replaced speakers
• Cut factory wiring
• Added amplifier
• Removed factory amplifier
• Line-output converter
• Aftermarket subwoofer
• Poor-quality repairs
• Incorrectly connected speakers

The system should be inspected before a replacement package is quoted.

Age-related issues may include:

• Deteriorated speaker surrounds
• Brittle connectors
• Water-damaged door speakers
• Failed amplifier channels
• Loose trim
• Aged wiring repairs
• Rattling rear shelves
• Deteriorated acoustic foam

Where the original speaker has failed, installing a quality Focal replacement can improve reliability and sound. However, the replacement must still match the original system appropriately.

Older vehicles can also benefit from modern DSP tuning, but the installation should be planned around the condition and value of the vehicle rather than adding unnecessary complexity.

8. Can an Infiniti QX30, QX50, QX55, QX60, QX70 or QX80 be upgraded?

Potentially, yes.

Infiniti crossovers and SUVs can provide more cabin and cargo space for amplifiers, DSP units and subwoofers, but they may also have more complex multi-speaker factory systems.

Potential upgrades include:

• Front component speakers
• Rear coaxial speakers
• Dashboard speakers
• Centre speaker
• Additional amplification
• Digital signal processing
• Factory-subwoofer integration
• Custom subwoofer enclosure
• Focal BAM treatment
• Multi-seat acoustic tuning

The QX30 should not automatically be treated as a typical Nissan-based audio installation. It shares substantial platform architecture with selected Mercedes-Benz vehicles, and exact audio compatibility must be established independently.

Selected QX50 and QX55 vehicles use a 16-speaker Bose Performance Series system containing an amplifier, processing, tweeters and a subwoofer.

Selected QX60 vehicles may use multi-speaker Bose Performance Series systems.

QX70 vehicles commonly use Bose premium audio, while QX80 systems can differ substantially by generation, production year and market.

SUV installation planning should consider:

• Three-row seating
• Passenger coverage
• Cargo-space requirements
• Folding seats
• Spare-wheel access
• Factory subwoofer
• Cargo restraints
• Vehicle tools
• Towing equipment
• Existing accessories
• Equipment ventilation
• Safe amplifier mounting
• Subwoofer restraint

A system may be tuned primarily for:

• Driver
• Both front seats
• Front and second rows
• General whole-cabin coverage

These tuning goals involve compromises. A system optimised precisely for the driver may not provide identical imaging for passengers in other seats.

The owner’s preferred listening positions should be discussed before DSP tuning is completed.

9. How do Bose AudioPilot, Centerpoint and active noise control affect an Infiniti upgrade?

Selected Infiniti Bose systems may use AudioPilot, Centerpoint, Driver’s Audio Stage or other signal-processing functions.

Bose AudioPilot uses a cabin microphone and vehicle information to modify volume or sound quality in response to changing road and cabin noise.

Bose Centerpoint can create a surround-style presentation from a conventional stereo recording.

Driver’s Audio Stage may alter the sound to favour the driver’s seating position.

Selected vehicles may also use active noise-control or engine-sound-management functions.

These systems can affect:

• Frequency response
• Channel balance
• Centre-channel output
• Surround-speaker output
• Bass level
• Volume behaviour
• Signal delay
• Microphone operation
• Perceived tonal balance

An aftermarket amplifier should not be connected until the available factory signals have been measured under different operating conditions.

Testing may need to include:

• Low volume
• High volume
• AudioPilot on and off
• Centerpoint on and off
• Driver’s Audio Stage on and off
• Vehicle stationary
• Vehicle moving
• Different audio sources
• Telephone calls
• Navigation prompts
• Engine running
• Different drive modes

Active noise control can use the audio system to reproduce calculated cancellation signals. Removing or replacing speakers without understanding that function can reduce its effectiveness or create unexpected noises.

Factory microphones should not be covered or relocated casually.

A correctly configured DSP may help manage the processed factory signals, but it cannot remove every factory characteristic if the selected input channels do not contain a suitable clean signal.

The installer may need to retain selected factory equipment or disable particular functions using a verified and reversible process.

10. Can the original Infiniti InTouch system, cameras and controls be retained?

In most Infiniti upgrades, retaining the original infotainment system will be the preferred approach.

Depending on the vehicle, Infiniti InTouch may control or display:

• Radio
• Bluetooth audio
• Hands-free telephone
• Navigation
• Apple CarPlay
• Android Auto
• Vehicle settings
• Climate controls
• Around View Monitor
• Reversing camera
• Parking information
• Audio settings
• Voice recognition
• Connected services
• Maintenance information

Removing the original head unit or display can affect more than music playback.

A compatible amplifier, DSP or signal interface may allow the factory source system to remain in place.

Before installation, the dealer should test:

• Output voltage
• Frequency response
• Factory equalisation
• Crossover filtering
• Signal polarity
• Signal delay
• Volume behaviour
• Telephone-audio routing
• Navigation-prompt routing
• Warning-sound routing
• Start-up behaviour
• Shutdown behaviour
• Vehicle sleep behaviour

After the upgrade, the dealer should confirm:

• Radio operation
• Bluetooth audio
• Telephone calls
• Factory microphone
• Navigation
• Navigation prompts
• Apple CarPlay
• Android Auto
• Steering-wheel controls
• Around View Monitor
• Reversing camera
• Parking sensors
• Climate-control display
• Warning and notification sounds
• Amplifier start-up and shutdown
• Acceptable standby current

The upgrade should improve sound without sacrificing the technology and controls that are integrated into the vehicle.

11. How are the correct Infiniti speaker sizes and impedance determined?

The vehicle should be physically inspected and measured rather than relying solely on a general online fitment list.

Physical compatibility depends on:

• Nominal speaker diameter
• Actual cut-out diameter
• Basket shape
• Mounting-hole pattern
• Magnet diameter
• Installation depth
• Window clearance
• Door-trim clearance
• Dashboard clearance
• Factory grille
• Connector design
• Required adaptor thickness
• Moisture protection

Electrical compatibility depends on:

• Nominal speaker impedance
• Measured DC resistance
• Factory radio output
• Bose amplifier output
• Frequency range supplied to the speaker
• Active crossover filtering
• Factory equalisation
• Signal delay
• Signal polarity
• Speaker-protection processing

The installer may use:

• Physical measurement
• Multimeter testing
• Oscilloscope testing
• Polarity testing
• Real-time frequency analysis
• Test signals
• Vehicle-specific technical information

A speaker measuring close to 2 ohms should not automatically be replaced with a 4-ohm speaker without considering the potential reduction in output.

Likewise, a lower-impedance speaker should not be connected to a source or amplifier that is not designed to operate safely at that load.

A suitable adaptor may be required to:

• Hold the speaker securely
• Preserve original mounting points
• Maintain correct alignment
• Create an acoustic seal
• Reduce resonance
• Prevent window contact
• Retain factory trim
• Protect the speaker from moisture

Tweeter and dashboard-speaker installation must not interfere with:

• Factory grille
• Dashboard trim
• Door trim
• Side-curtain airbags
• Wiring
• Windscreen demisting
• Cabin microphones
• Active noise-control microphones
• Light or temperature sensors

Speaker diameter alone is not enough to confirm Infiniti compatibility.

12. Does an Infiniti audio upgrade require an amplifier or DSP?

Not every Infiniti speaker upgrade requires both.

Efficient, compatible Focal speakers may provide an improvement when powered by a suitable factory radio or amplifier.

This may suit an owner seeking:

• Clearer vocals
• Improved treble detail
• Better tonal balance
• Stronger mid-bass
• Cleaner moderate-volume performance
• Improved telephone clarity

An amplifier may provide:

• Greater clean volume
• Improved speaker control
• Stronger dynamics
• Better mid-bass
• Reduced distortion
• Increased headroom
• Power for a subwoofer

A DSP can allow the installer to:

• Measure and correct the factory signal
• Combine compatible channels
• Set crossover frequencies
• Balance individual speakers
• Apply corrective equalisation
• Adjust time alignment
• Improve stereo imaging
• Manage the centre channel
• Integrate a subwoofer
• Tune for selected seating positions

DSP is particularly useful where the Bose amplifier sends different frequency ranges to different speakers.

Signals should only be combined after their frequency content, polarity, delay and processing have been measured.

Combining incompatible channels can produce:

• Acoustic cancellation
• Uneven frequency response
• Weak bass
• Harsh treble
• Poor stereo imaging
• Inconsistent behaviour at different volume levels

A DSP can correct many limitations, but it cannot recreate frequencies that are completely absent from the selected source channels.

Before an amplifier is installed, the dealer should assess:

• Speaker impedance
• Required RMS power
• Number of channels
• Battery condition
• Alternator or DC-to-DC converter capacity
• Cable size
• Fuse protection
• Earthing
• Equipment ventilation
• Standby current
• Vehicle sleep behaviour
• Existing accessories

Correct product matching, installation and tuning are more important than selecting equipment solely by its advertised maximum power.

13. Can a subwoofer and Focal BAM treatment be added to an Infiniti?

In many Infiniti vehicles, yes.

A correctly integrated subwoofer can provide:

• Deeper bass
• Greater low-frequency impact
• Improved bass control
• Reduced demand on the door speakers
• Cleaner moderate-volume performance
• A fuller and more balanced sound

Potential Focal bass solutions may include:

• ISUB ACTIVE
• ISUB ACTIVE 2.1
• ISUB TWIN
• Selected Specialised Subwoofers
• Conventional Focal subwoofers
• Compact sealed enclosures
• Boot-side installations
• Under-seat installations where clearance permits
• Spare-wheel-area installations
• Removable cargo-area enclosures
• Custom enclosures

The correct solution depends on:

• Exact Infiniti model
• Sedan, coupe, convertible or SUV body
• Available space
• Factory amplifier
• Factory subwoofer
• Available source signal
• Required bass level
• Electrical capacity
• Boot or cargo requirements
• Folding-seat operation
• Spare-wheel access
• Hybrid equipment

Existing factory bass channels must be assessed before another subwoofer is added.

Correct crossover frequency, polarity, phase, level and signal delay are essential.

Poor integration can make the subwoofer sound disconnected from the front speakers or create cancellation that reduces bass at the listening position.

Focal BAM acoustic treatment may help:

• Strengthen the speaker mounting environment
• Reduce door-panel resonance
• Reduce sound escaping through the outer door skin
• Improve mid-bass response
• Reduce selected rattles
• Reduce selected road and tyre noise
• Improve clarity at motorway speeds
• Create a more controlled acoustic environment

Potential treatment areas include:

• Front doors
• Rear doors
• Speaker mounting surfaces
• Rear quarter panels
• Rear shelf
• Boot or cargo panels
• Tailgate
• Wheel-arch areas
• Loose trim interfaces

Treatment must not interfere with:

• Door drainage
• Window mechanisms
• Door locks
• Wiring
• Side airbags
• Pressure sensors
• Cabin microphones
• Active noise-control microphones
• Seat mechanisms
• Battery ventilation
• Hybrid equipment
• Cabin vents
• Manufacturer service access

Acoustic treatment should be applied strategically. Covering every available surface can add unnecessary weight and cost without producing a proportionate improvement.

14. Can Infiniti hybrid, imported and discontinued vehicles be upgraded?

Potentially, yes, but they may require additional investigation.

Hybrid Infiniti models include selected versions of:

• M35h
• Q50 Hybrid
• Q70 Hybrid

A hybrid audio installation must avoid:

• High-voltage wiring
• High-voltage batteries
• Orange high-voltage connectors
• Battery ventilation
• Cooling equipment
• DC-to-DC converter equipment
• Hybrid control modules
• Manufacturer service areas

The 12-volt electrical system must still be assessed before additional amplification is installed.

The presence of a high-voltage traction battery does not mean an audio amplifier can be connected directly to it.

Imported vehicles may have different:

• Factory audio systems
• Bose configurations
• Connectors
• Infotainment software
• Radio frequencies
• Navigation systems
• Speaker mounting
• Amplifier coding
• Replacement-part availability

Many Infiniti vehicles in Australia are now used vehicles, and some models were discontinued years ago.

This does not prevent an audio upgrade, but age and parts availability should be considered.

The installer should check for:

• Deteriorated factory speakers
• Brittle trim clips
• Damaged connectors
• Previous repairs
• Water leaks
• Failed factory amplifier
• Unsupported infotainment functions
• Missing technical information
• Limited replacement trim availability

Permanent alterations should be avoided where replacement interior components are difficult to obtain.

Owners should also understand that product, vehicle and installation responsibilities may be separate. Any concern about vehicle coverage should be discussed with the relevant vehicle service provider before modification.

15. How do I confirm compatibility, and what will an Infiniti audio upgrade cost?

Begin by collecting the vehicle’s complete information.

Provide the dealer with:

• Exact Infiniti model
• Production month and year
• Vehicle Identification Number
• Chassis or model code
• Sedan, coupe, convertible, crossover or SUV body
• Australian-delivered or imported specification
• Equipment grade
• Petrol, diesel or hybrid powertrain
• Standard or Bose audio system
• Number and location of speakers
• Factory amplifier
• Factory subwoofer
• Infiniti InTouch system
• Active noise-control functions
• Previous audio modifications
• Preferred listening position
• Boot or cargo-space requirements
• Desired performance
• Available budget

Physical compatibility can be affected by:

• Speaker diameter
• Basket shape
• Mounting-hole pattern
• Magnet diameter
• Installation depth
• Factory connector
• Grille clearance
• Window clearance
• Door-mechanism clearance
• Tweeter position
• Required mounting spacer
• Moisture protection

Electrical and acoustic compatibility can be affected by:

• Factory speaker impedance
• Bose amplifier output
• Active frequency filtering
• Factory equalisation
• Signal delay
• Centre-channel processing
• AudioPilot
• Centerpoint
• Driver’s Audio Stage
• Active noise control
• Telephone-audio routing
• Navigation-prompt routing
• Notification-sound routing
• Vehicle sleep and wake behaviour
• Hybrid electrical requirements

The cost depends on:

• Exact Infiniti model
• Factory audio configuration
• Focal speaker range selected
• Number of speakers
• Custom mounting adaptors
• Connector adaptation
• Tweeter installation
• Acoustic treatment
• Amplifier installation
• DSP integration
• Bose-system integration
• Subwoofer selection
• Interior disassembly
• Custom fabrication
• Hybrid complexity
• Final measurement and tuning

A front-speaker replacement in a compatible, non-amplified vehicle may be considerably less complex than a complete amplified and DSP-tuned system in a Bose-equipped Q50, Q60, Q70, QX50, QX70 or QX80.

It would be misleading to provide one standard Infiniti audio-upgrade price without first identifying and assessing the vehicle.

The compatibility table on this page should be used as a starting point only. Exact model names, production years and factory audio specifications should be independently confirmed before purchase.

Genuine Focal products purchased through an Authorised Focal Australia Dealer receive the applicable Australian Focal product warranty and support.

Upgrade Your Infiniti with Focal Sound

Whether you drive an Infiniti G35, G37, M35, M37, M45, Q30, Q45, Q50, Q60, Q70, EX35, FX35, QX30, QX50, QX56, QX60, QX70, QX80 or another model, there may be a professionally designed Focal audio upgrade available.

Selected vehicles may be compatible with Focal Inside products including:

• IS RNS 165 component speakers
• IC RNS 165 coaxial speakers

These products should only be promoted as Plug & Play after compatibility with the exact vehicle, speaker position and factory audio system has been confirmed.

Other vehicles may require a customised system using suitable products from ranges including:

• Auditor
• Universal
• Access
• Slatefiber
• Flax Evo
• K2 Power
• K2 Power M
• Utopia M
• Focal amplifiers
• Focal DSP solutions
• Focal subwoofers
• Focal BAM acoustic treatment

Depending on the vehicle and desired result, an installation may include:

• Front speaker replacement
• Rear speaker replacement
• Dashboard speakers
• Custom mounting adaptors
• Factory connector adaptation
• Bose amplifier integration
• Factory-infotainment retention
• Additional amplification
• Digital signal processing
• Factory-subwoofer integration
• Additional bass reinforcement
• Professional acoustic measurement and tuning

Infiniti audio systems vary substantially between models, generations and equipment grades. Standard systems, Bose premium audio, centre channels, factory subwoofers, AudioPilot, Centerpoint, active noise control and hybrid electrical systems all require careful product selection and installation planning.

A correctly designed and professionally installed Focal system can provide stronger bass control, clearer vocals, improved stereo imaging, greater musical detail and cleaner performance at higher listening levels while retaining the Infiniti’s original infotainment system, controls, cameras, connected functions and premium interior appearance.
