MAZDA

Upgrade your Mazda’s factory audio system with Focal Inside Plug & Play speaker kits from Focal Australia. Each vehicle-specific package is engineered for OEM fitment in popular models such as Mazda 3, CX-5 and BT-50, using original mounting points and plug-in connectors so there’s no cutting, no splicing and no permanent modification to the cabin. Installation is clean, fast and fully reversible, making these kits ideal for both daily drivers and touring setups.

By replacing the standard Mazda speakers with high-performance Focal drivers, these Plug & Play kits deliver stronger mid-bass, clearer vocals and smoother, more detailed highs than the factory system can offer. You keep your original Mazda head unit, steering wheel controls and infotainment features, while enjoying a far more engaging, dynamic in-car listening experience on every commute, weekend trip or long-distance drive.

Upgrade your Mazda factory audio with compatible Focal Inside speakers or a professionally designed custom Focal sound system.

Mazda vehicles are known for their driver-focused interiors, enjoyable handling and refined everyday usability. However, the original audio system can still lack the clarity, mid-bass impact, detail and clean output that many owners want.

Depending on the model, production date and factory audio configuration, a Mazda speaker upgrade may include:

• Compatible Focal Inside speakers
• Front component speaker replacement
• Rear coaxial speaker replacement
• Tweeter installation or adaptation
• Factory-connector integration
• Original infotainment retention
• Additional amplification
• Digital signal processing
• Compact subwoofer integration
• Focal BAM acoustic treatment
• Professional acoustic measurement and tuning

Selected Mazda vehicles appear in the Focal Inside compatibility system and may use products including:

• IS FORD 165 component speakers
• IC FORD 165 coaxial speakers
• IC TOY 165 coaxial speakers
• Impulse 4.320 amplifier
• IW FORDV2 YISO harness
• ISUB ACTIVE
• ISUB ACTIVE 2.1
• ISUB TWIN

Although some of these products carry Ford or Toyota in their product name, they are also listed for selected Mazda applications where their mounting dimensions, connectors and electrical specifications have been confirmed as compatible.

This does not mean that these products are suitable for every Mazda.

Compatibility can change according to:

• Exact Mazda model
• Model generation
• Production month and year
• Australian-delivered or imported specification
• Factory speaker configuration
• Standard or Bose audio
• Factory amplifier
• Speaker impedance
• Speaker mounting depth
• Tweeter location
• Infotainment generation
• Previous audio modifications

Focal Plug & Play amplifier harnesses are generally intended for compatible non-amplified factory systems using the original head unit. They must not be assumed compatible with Bose or other factory-amplified Mazda systems.

The correct products should always be confirmed for the exact vehicle before purchase or installation.

1. Can a Mazda factory audio system be upgraded with Focal speakers?

In many cases, yes.

Selected Mazda vehicles have compatible Focal Inside speaker solutions, while other models can potentially be upgraded using products from Focal’s custom-installation ranges.

A professionally completed Mazda speaker upgrade may provide:

• Clearer vocals
• Improved treble detail
• Stronger mid-bass
• Better instrument separation
• Reduced distortion
• Greater clean volume
• Improved tonal balance
• A wider and more focused soundstage
• Deeper and better-controlled bass
• More enjoyable listening at motorway speeds

Before selecting speakers, the installer should identify:

• Exact Mazda model
• Production month and year
• Model generation
• Equipment grade
• Australian-delivered or imported specification
• Factory infotainment system
• Number and location of speakers
• Standard, Mazda Harmonic Acoustics, Bose or other audio system
• Factory amplifier
• Factory subwoofer
• Original speaker impedance
• Previous audio modifications

The vehicle may also need to be physically inspected to confirm:

• Speaker diameter
• Speaker basket shape
• Mounting-hole pattern
• Installation depth
• Magnet clearance
• Factory grille clearance
• Window clearance
• Connector type
• Tweeter mounting location
• Required mounting adaptor
• Speaker polarity
• Interior trim clearance

A speaker having the same advertised diameter as the original Mazda speaker is not automatically compatible.

The factory speaker may have an unusual basket, low impedance, shallow mounting depth, integrated spacer or vehicle-specific connector. These details must be checked before a replacement is selected.

2. Is there a dedicated Mazda Focal Inside Plug & Play speaker kit?

Selected Mazda models have confirmed Focal Inside applications, but Focal Australia does not currently display a speaker kit carrying a dedicated Mazda product name.

Instead, the Mazda compatibility guide lists selected cross-brand Focal Inside products, including:

• IS FORD 165
• IC FORD 165
• IC TOY 165
• IW FORDV2 YISO harness

These products may be compatible with particular Mazda vehicles because manufacturers sometimes share:

• Speaker dimensions
• Mounting-hole patterns
• Electrical connectors
• Door structures
• Infotainment architecture
• Vehicle platforms

For example, the second-generation Mazda BT-50 was closely related to the Ford Ranger platform. This allows selected Ford-named Focal Inside products to be used in compatible 2012–2020 BT-50 vehicles.

However, the product name alone does not prove compatibility.

A product should only be described as Plug & Play when the complete installation has been confirmed, including:

• Physical speaker fitment
• Factory connector compatibility
• Tweeter mounting
• Speaker impedance
• Available factory power
• Factory amplifier configuration
• Full-range signal availability
• Required installation accessories

Some Mazda applications may require tweeter grille, plug or bracket adaptation. Those installations should not be described as completely modification-free.

Where custom spacers, connectors, wiring or fabrication are required, the system should be described as a tailored Focal audio installation rather than a fully Plug & Play upgrade.

3. Which Mazda models currently have listed Focal Inside compatibility?

The current Focal Australia Mazda compatibility guide lists products for selected versions of the following vehicles.

Mazda2 Hybrid IV

Selected 2022–2025 Mazda2 Hybrid IV vehicles may accept:

• IC TOY 165 rear coaxial speakers

The Mazda2 Hybrid is based on a Toyota platform and is not the same vehicle as every Australian-delivered Mazda2.

Compatibility must not be transferred automatically between Mazda2 variants.

Mazda3 BM/BN

Selected five-door Mazda3 BM and BN vehicles manufactured between 2014 and 2019 may accept:

• IC FORD 165 rear coaxial speakers

The current table does not confirm a complete front and rear Focal Inside system for this application.

Mazda6 GJ/GL

Selected Mazda6 sedan and wagon vehicles may accept:

• IC FORD 165 rear coaxial speakers

The table includes selected 2012–2024 applications, but the exact body, production date and factory audio system must still be confirmed.

The table does not confirm a complete front, centre, rear and subwoofer replacement system.

Mazda Demio

Selected 2015–2022 Japanese-market Demio vehicles may accept:

• IS FORD 165 front component speakers
• IC FORD 165 rear coaxial speakers

Tweeter adaptation may be required.

Demio compatibility should not automatically be applied to an Australian Mazda2 without confirming the platform, build date and factory equipment.

Mazda MX-5 ND

Selected 2015–2024 Mazda MX-5 ND soft-top vehicles may accept:

• IS FORD 165 front component speakers

Selected 2016–2024 MX-5 RF vehicles may also accept:

The standard and Bose audio systems must be treated as separate applications.

Mazda BT-50 II

Selected Ford Ranger-based 2012–2020 Mazda BT-50 vehicles may accept:

• IS FORD 165 front component speakers
• IC FORD 165 rear coaxial speakers
• IW FORDV2 YISO harness
• Impulse 4.320 amplifier, where compatible

Amplifier and harness integration applies only to compatible non-amplified factory systems using the original head unit.

Every application remains subject to confirmation by vehicle model, build date and original audio system.

4. Which current Mazda models are not yet confirmed by the compatibility guide?

Many current Mazda vehicles are not presently displayed in the Focal Australia Mazda compatibility table.

These include:

• Current Mazda2
• Mazda3 BP
• Mazda CX-30
• 2026 Mazda CX-5
• Mazda CX-6e
• Mazda CX-60
• Mazda CX-70
• Mazda CX-80
• Mazda CX-90
• Mazda 6e
• Current Isuzu D-MAX-based Mazda BT-50
• Other newer, imported or electrified Mazda models

The absence of a model from the Focal Inside table does not necessarily mean that it cannot be upgraded.

It means that a Plug & Play product combination should not be promised without further investigation.

A custom Focal installation may still be possible using:

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

A custom installation may require:

• Vehicle-specific speaker spacers
• Custom mounting adaptors
• Connector adaptation
• New speaker wiring
• Factory-signal measurement
• Speaker-level signal interfaces
• Additional amplification
• Digital signal processing
• Professional acoustic tuning

New-generation Mazda vehicles may also integrate infotainment, cameras, navigation, telephone audio, driver-assistance warnings and vehicle settings through the original source system.

The original infotainment should normally be retained, with the audio upgrade integrated downstream from it.

5. Can a Mazda3 sound system be upgraded?

Potentially, yes, but the Mazda3 generation and audio system must be identified first.

Mazda3 generations include:

• Mazda3 BK
• Mazda3 BL
• Mazda3 BM
• Mazda3 BN
• Mazda3 BP

The Focal Australia guide currently lists IC FORD 165 rear coaxial speakers for selected five-door Mazda3 BM and BN vehicles manufactured between 2014 and 2019.

This is not confirmation of a complete front and rear Plug & Play upgrade.

Depending on the vehicle, a Mazda3 may have:

• Standard factory audio
• Mazda Harmonic Acoustics
• Bose premium audio
• Factory amplification
• Dashboard woofers or midrange speakers
• Door speakers
• Centre speaker
• Factory low-frequency speakers
• Active crossover filtering
• Vehicle-specific equalisation

The Mazda3 BP introduced a substantially different speaker architecture from earlier Mazda3 generations. Speakers may be positioned and loaded differently within the cabin, so compatibility information from the BM or BN generation should not be carried forward.

Before replacing speakers, the installer should confirm:

• Exact Mazda3 generation
• Hatch or sedan body
• Standard or Bose audio
• Speaker locations
• Speaker impedance
• Factory amplifier
• Signal frequency range
• Active crossover points
• Available installation depth
• Factory connector type

A suitable Mazda3 upgrade may include:

• Compatible rear coaxial speakers
• Custom front component speakers
• Additional amplification
• DSP correction and tuning
• Compact subwoofer integration
• Strategic door treatment

Mazda3 Bose systems require separate measurement and system design.

6. Can Mazda CX-3 and CX-5 speakers be upgraded?

Selected CX-3 and CX-5 vehicles have Focal Inside applications, but compatibility depends on generation and factory audio.

Mazda CX-3

Selected 2018–2021 CX-3 vehicles may use:

• IS FORD 165 front component speakers
• IC FORD 165 rear coaxial speakers

The compatibility guide notes that tweeter adaptation may be required.

This could involve:

• Tweeter connector adaptation
• Tweeter bracket adaptation
• Grille modification
• Custom positioning behind the original grille

For this reason, the installation should not be advertised as universally modification-free.

The CX-3 may also be equipped with a seven-speaker Bose system. Bose-equipped vehicles are a separate amplified application and should not use the standard non-amplified recommendation without testing.

Mazda CX-5

Selected first-generation CX-5 vehicles from 2012–2017 currently have a listed rear coaxial option.

Selected second-generation 2017–2025 CX-5 vehicles may use:

• IS FORD 165 front component speakers
• IC FORD 165 rear coaxial speakers

The 2026 third-generation CX-5 introduces new infotainment and audio architecture. Compatibility from the previous generation must not be assumed.

CX-5 Bose systems can include:

• Multiple amplified speaker channels
• Centre-channel processing
• Dedicated low-frequency speakers
• Active crossover filtering
• Factory equalisation
• Bose signal processing
• Speed-dependent audio adjustment

A Bose-equipped CX-5 requires measurement before any speaker, amplifier or DSP is selected.

7. Can a Mazda MX-5 or MX-5 RF audio system be upgraded?

Selected Mazda MX-5 ND vehicles may accept IS FORD 165 front component speakers.

The listed applications include selected:

• 2015–2024 MX-5 ND soft-top vehicles
• 2016–2024 MX-5 RF vehicles

The exact vehicle still needs to be checked because MX-5 audio systems can differ by:

• Production year
• Equipment grade
• Soft-top or RF body
• Standard or Bose audio
• Headrest speakers
• Factory amplifier
• Speaker impedance
• Door-speaker configuration
• Infotainment generation

An MX-5 presents several acoustic and installation challenges:

• Small cabin
• Limited door volume
• Restricted mounting depth
• High tyre and road noise
• Increased wind noise with the roof open
• Headrest or rear-fill speakers
• Limited amplifier mounting space
• Limited subwoofer space
• Weight sensitivity

A suitable MX-5 upgrade may include:

• Front component speakers
• Compact amplification
• Driver-focused DSP tuning
• Strategic door treatment
• A compact under-seat or custom subwoofer
• Separate roof-open and roof-closed tuning presets

The soft-top and RF should be treated as different acoustic environments.

The system should be tested with:

• Roof closed
• Roof open
• Windows raised
• Windows lowered
• Normal urban speeds
• Motorway speeds

Replacing the door speakers alone may improve clarity, but amplification, tuning and bass integration may be needed for a more complete result.

8. Can a Mazda BT-50 audio system be upgraded with Focal?

Yes, but the generation is extremely important.

2012–2020 Mazda BT-50

The second-generation BT-50 shared significant platform architecture with the Ford Ranger.

Selected 2012–2020 vehicles may therefore use:

• IS FORD 165 front component speakers
• IC FORD 165 rear coaxial speakers
• IW FORDV2 YISO harness
• Impulse 4.320 amplifier

Focal Australia also offers a Mazda BT-50 6.0 Pack for selected compatible vehicles from this generation.

The amplifier harness is intended for compatible factory head units and non-amplified systems. It should not be assumed compatible with:

• Factory premium audio
• Factory-amplified audio
• Aftermarket head units
• Previously modified wiring
• Non-standard infotainment systems

Current Mazda BT-50

The current BT-50 is based on the Isuzu D-MAX platform rather than the Ford Ranger platform.

Compatibility information for the 2012–2020 BT-50 must not be applied to the current generation.

The current BT-50 may require:

• Different speakers
• Different connectors
• Different mounting adaptors
• Different amplifier harness
• Isuzu-platform compatibility confirmation
• Custom signal integration

A BT-50 used for work, towing or touring may also contain:

• UHF radio
• Trailer brake controller
• Dual-battery system
• DC-to-DC charger
• Solar controller
• Inverter
• Driving lights
• Auxiliary switch panel
• Tracking equipment
• Canopy power system
• Camping equipment

These systems should be considered when designing amplifier power, cable routes, earthing and equipment mounting.

9. Can a Mazda Bose factory audio system be upgraded?

Potentially, but it should not be treated as a conventional Plug & Play speaker replacement.

Mazda Bose systems may include:

• Low-impedance speakers
• Dedicated multi-channel amplification
• Centre speaker
• Dashboard speakers
• Door woofers
• Rear speakers
• Surround processing
• Factory subwoofer
• Active crossover filtering
• Vehicle-specific equalisation
• Bose Centerpoint processing
• Bose AudioPilot noise compensation
• Volume-dependent processing

Before replacing a Bose speaker, the installer should measure:

• Speaker impedance
• Factory amplifier output voltage
• Frequency range supplied to each speaker
• Active crossover points
• Signal polarity
• Factory equalisation
• Volume-dependent processing
• Subwoofer signal
• Centre-channel processing
• Warning-sound routing

Connecting a conventional four-ohm replacement speaker to a channel designed for a different load may cause:

• Reduced volume
• Incorrect tonal balance
• Amplifier protection
• Excessive amplifier load
• Distortion
• Poor integration with retained speakers

A suitable Bose-system upgrade may involve:

• Retaining the original infotainment
• Retaining selected Bose speakers
• Improving the primary front soundstage
• Adding an integration-compatible DSP
• Adding aftermarket amplification
• Integrating a separate Focal subwoofer
• Professionally measuring and tuning the completed system

Replacing every Bose speaker is not automatically the best approach.

10. Which Focal speaker range is best for a Mazda?

The best Focal range depends on the vehicle, factory audio system, installation space, amplifier power and owner’s expectations.

Focal Inside

Focal Inside is the preferred starting point where a compatible vehicle-specific product is listed.

Potential benefits include:

• Original speaker-location use
• Compatible mounting dimensions
• Vehicle-style connectors
• Simplified installation
• Clean factory appearance
• Reversible installation where applicable

Auditor

Auditor may suit an affordable replacement for basic, damaged or worn factory speakers where custom mounting can be accommodated.

Universal

Focal Universal products include flexible and shallow-fitment options that may suit restricted Mazda door or dashboard locations.

Access

Access provides dynamic and engaging performance for everyday systems where strong output and value are priorities.

Slatefiber

Slatefiber offers increased control, detail and dynamics for owners seeking a more refined system.

Flax Evo

Flax Evo may suit a premium Mazda installation where natural vocals, tonal balance and musical detail are important.

K2 Power

K2 Power is intended for high-performance systems requiring strong dynamics, precision and increased power handling.

K2 Power M

K2 Power M offers modular speaker options for advanced multi-channel and custom-designed installations.

Utopia M

Utopia M is designed for uncompromising systems where amplification, mounting, acoustic treatment and DSP tuning are engineered around the speakers.

The most expensive speaker is not automatically the correct choice.

Product selection should consider:

• Factory speaker impedance
• Available source signal
• Amplifier power
• Installation depth
• Speaker diameter
• Required listening volume
• Road, tyre and wind noise
• Owner’s preferred music
• Number of listening positions
• Available budget
• Installation complexity

Premium Focal speakers require suitable amplification, rigid mounting and professional tuning to provide their intended performance.

11. Can the original Mazda infotainment and vehicle functions be retained?

In most modern Mazda installations, retaining the original infotainment system is the preferred approach.

Depending on the vehicle, the factory system may control:

• Radio and media
• Bluetooth
• Telephone calls
• Apple CarPlay
• Android Auto
• Mazda Connected Services
• Factory microphone
• Navigation
• Steering-wheel controls
• Reversing camera
• Surround-view cameras
• Parking information
• Vehicle settings
• Driver-assistance settings
• Audible warnings
• Electric and hybrid vehicle information

Replacing the factory source system could affect functions unrelated to music.

A suitable amplifier, DSP or signal interface may allow the audio system to be improved downstream from the original source.

Before installation, the dealer should test:

• Speaker-level outputs
• Output voltage
• Frequency response
• Factory equalisation
• Signal polarity
• Available full-range channels
• Volume behaviour
• Balance and fade
• Telephone-audio routing
• Navigation-prompt routing
• Parking-warning routing
• Driver-assistance warning routing
• Start-up behaviour
• Shutdown behaviour
• Vehicle sleep behaviour

After installation, the dealer should confirm:

• Radio and media operation
• Bluetooth audio
• Telephone calls
• Factory microphone
• Apple CarPlay
• Android Auto
• Navigation prompts
• Steering-wheel controls
• Camera operation
• Parking information
• Vehicle settings
• Driver-assistance warnings
• Amplifier start-up
• Amplifier shutdown
• Acceptable standby current

Retaining the original Mazda infotainment does not mean the audio performance must remain factory standard.

12. Does a Mazda speaker upgrade require an amplifier or DSP?

Not every compatible Mazda speaker upgrade requires both.

Efficient and electrically compatible Focal Inside speakers may provide an improvement when powered from a compatible standard factory head unit.

This may suit an owner seeking:

• Clearer vocals
• Improved treble
• Better tonal balance
• Stronger mid-bass
• Cleaner moderate-volume performance
• Replacement of damaged factory speakers

A factory head unit generally has limited clean power.

An aftermarket amplifier may provide:

• Greater clean volume
• Improved speaker control
• Stronger dynamics
• Better mid-bass
• Reduced distortion
• Increased headroom
• Power for a subwoofer
• Improved performance against road and tyre noise

The Focal Impulse 4.320 may be installed with a compatible Plug & Play harness in selected non-amplified Mazda applications.

Harness compatibility depends on:

• Original factory head unit
• Non-amplified audio configuration
• Correct vehicle generation
• Correct connector
• Required power wiring
• Available mounting location

A DSP can allow the installer to:

• Measure and correct the factory signal
• Set crossover frequencies
• Balance individual speakers
• Apply corrective equalisation
• Adjust time alignment
• Improve stereo imaging
• Integrate a subwoofer
• Manage centre and surround channels
• Tune primarily for the driver
• Create alternative tuning presets

DSP may be especially valuable when:

• Factory equalisation is substantial
• Different outputs receive different frequency ranges
• The vehicle has Bose amplification
• A subwoofer is being added
• Premium Focal speakers are selected
• A multi-channel amplifier is installed
• The owner wants a carefully tuned soundstage

A DSP cannot recreate frequency information that is completely absent from its input signal.

The available factory signals must be measured before the system is designed.

13. Can a subwoofer be added without compromising Mazda practicality?

In many Mazda vehicles, yes.

A correctly integrated subwoofer can provide:

• Deeper bass
• Greater low-frequency impact
• Better bass control
• Reduced demand on door speakers
• Cleaner moderate-volume performance
• Fuller and more balanced sound

Potential Focal bass solutions include:

• ISUB ACTIVE
• ISUB ACTIVE 2.1
• ISUB TWIN
• Specialised Subwoofers
• Compact sealed enclosures
• Under-seat installations
• Cargo-area side enclosures
• Removable enclosures
• Custom vehicle-specific enclosures

The correct solution depends on:

• Mazda model
• Available clearance
• Seat adjustment
• Passenger space
• Factory audio system
• Available source signal
• Required bass output
• Electrical capacity
• Cargo requirements
• Existing factory subwoofer
• Spare-wheel access
• Tool storage
• Touring equipment
• Vehicle service access

A Mazda2, Mazda3, CX-3 or MX-5 may benefit from a compact active subwoofer rather than a large luggage-area enclosure.

A CX-5, CX-60, CX-80, CX-90 or BT-50 may provide more installation possibilities, but cargo capacity, folding seats, touring equipment and factory electronics still need to be considered.

Apparently unused space may contain:

• Seat mechanisms
• Airbag wiring
• Floor contours
• Ventilation ducts
• Vehicle-control modules
• Battery equipment
• Hybrid or electric components
• Accessory wiring
• Spare-wheel equipment
• Service access points

The installation should preserve:

• Seat adjustment
• Passenger comfort
• Cargo capacity
• Folding-seat operation
• Spare-wheel access
• Tool storage
• Charging-cable storage
• Touring equipment
• Vehicle ventilation
• Manufacturer service access

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

Any enclosure must be securely restrained.

14. Can Focal BAM acoustic treatment improve a Mazda?

Strategically installed Focal BAM acoustic treatment may provide a worthwhile improvement.

A Mazda may experience:

• Tyre noise
• Road noise
• Wind noise
• Door-panel resonance
• Dashboard vibration
• Cargo-area resonance
• Interior trim vibration
• Speaker energy escaping through metal panels
• Reduced mid-bass performance
• Rattles at particular frequencies

Focal BAM treatment may help:

• Strengthen the speaker mounting environment
• Reduce door-panel resonance
• Reduce sound escaping through the outer door structure
• 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
• Outer door panels
• Rear quarter panels
• Cargo-area side panels
• Tailgate
• Rear cabin panels
• Selected floor areas
• Loose trim interfaces

Treatment must not interfere with:

• Door drainage
• Window mechanisms
• Door locks
• Wiring
• Side airbags
• Pressure sensors
• Seat-belt mechanisms
• Cabin ventilation
• Battery ventilation
• Vehicle-control modules
• Factory amplifier ventilation
• Manufacturer service access
• Identification and warning labels

Acoustic treatment should be applied strategically.

Covering every available surface can add unnecessary weight and cost without providing a proportionate improvement.

The most effective areas are normally:

• The speaker mounting surface
• The panel immediately behind the speaker
• Large resonant door sections
• Trim interfaces responsible for rattles
• Areas where useful speaker energy is escaping

BAM treatment will not make a Mazda completely silent. Its purpose is to improve the speaker environment and reduce selected resonance, vibration and sound transmission.

15. How do I confirm Mazda compatibility, and what will the upgrade cost?

Begin by collecting the vehicle’s complete information.

Provide the dealer with:

• Exact Mazda model
• Production month and year
• Vehicle Identification Number
• Model generation
• Equipment grade
• Australian-delivered or imported specification
• Petrol, diesel, hybrid or electric drivetrain
• Factory infotainment system
• Number and location of speakers
• Standard, Mazda Harmonic Acoustics, Bose or other audio system
• Existing factory amplifier
• Factory subwoofer
• Previous audio modifications
• Relevant vehicle software version
• Hatch, sedan, wagon, SUV, roadster or pickup body
• Preferred listening position
• Cargo and storage requirements
• Touring and work accessories
• 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
• Tweeter position
• Tweeter bracket
• Required mounting adaptor
• Required spacer thickness
• Moisture protection

Electrical and acoustic compatibility can be affected by:

• Factory speaker impedance
• Source-system output
• Factory amplifier
• Active frequency filtering
• Factory equalisation
• Signal polarity
• Available full-range signals
• Centre and surround processing
• Telephone-audio routing
• Navigation-prompt routing
• Warning-sound routing
• Factory-subwoofer integration
• Vehicle sleep and wake behaviour
• Hybrid or electric architecture
• Low-voltage electrical capacity

The cost depends on:

• Exact vehicle
• Factory audio configuration
• Focal speaker range selected
• Number of speakers
• Custom mounting adaptors
• Connector adaptation
• Tweeter installation
• Acoustic treatment
• Amplifier installation
• DSP integration
• Subwoofer selection
• Interior disassembly
• Custom fabrication
• Touring-equipment integration
• Final measurement and tuning

Installing rear coaxial speakers in a compatible standard-audio Mazda may be considerably less complex than integrating Focal speakers, amplification, DSP and a subwoofer with a multi-channel Bose system.

It would be misleading to provide one standard Mazda audio-upgrade price without identifying the exact vehicle.

The products displayed throughout the Focal Australia website are starting points for professional system design. They do not replace vehicle-specific compatibility confirmation.
