More Brand Information

Mitsubishi is a Japanese automaker headquartered in Tokyo, with automotive roots that go back to 1917, when the Mitsubishi group built the Mitsubishi Model A, often recognised as Japan’s first series-production passenger car. The modern car company was formed in 1970 as Mitsubishi Motors, spun out from the automobile division of Mitsubishi Heavy Industries, and it has since operated as a global brand within the wider Mitsubishi industrial ecosystem.

In real-world buyer terms, Mitsubishi is best known for SUVs, 4x4s and pickup trucks—vehicles built around durability, traction, and everyday practicality. Its most recognised nameplates include the Outlander (including the Outlander PHEV), the Pajero legacy (and Pajero Sport in many markets), the Triton / L200 pickup, plus mainstream crossovers and compact cars depending on region. Mitsubishi’s off-road credibility is not marketing fluff: the Pajero launched in 1982 and built a serious motorsport record in the Dakar Rally, first competing in 1983 and taking an overall win in 1985, with 12 total victories—which feeds directly into the brand’s “toughness + reliability” search intent.

Technology-wise, Mitsubishi is strongly associated with advanced traction and stability control, especially All Wheel Control and S-AWC (Super All Wheel Control)—an integrated vehicle dynamics system aimed at confident handling and stability across changing surfaces. On engines, MIVEC variable valve timing (first introduced in 1992) is another core Mitsubishi keyword tied to efficiency and performance balance. For electrification, the Outlander PHEV is a standout: Mitsubishi described it as the world’s first plug-in hybrid SUV, launched in 2013 and rolled out to 50+ countries, making it a flagship for “hybrid SUV” searches.

Mitsubishi’s strongest presence has long been export-driven across key regions, with proven strength in utility-focused markets where pickups and SUVs dominate—backed by global production and worldwide distribution, including pickup manufacturing history tied to Thailand for export. Its brand purpose is summed up by the “Drive your Ambition” positioning introduced in 2017: capability-led vehicles, increasingly supported by electrified tech, safety systems, and practical design that fits real owners, not showroom fantasies.

Speaker and Car Audio Upgrade FAQs

A professionally designed Mitsubishi speaker upgrade can deliver clearer vocals, stronger midrange, improved stereo imaging, cleaner volume and better bass while retaining the original dashboard, infotainment system and vehicle controls.

The correct solution, however, depends on much more than the Mitsubishi badge.

Mitsubishi vehicles sold in Australia include work utes, family SUVs, 4WD touring vehicles, plug-in hybrids, vans and passenger cars produced across several generations. Some are Mitsubishi-designed platforms. Others share architecture with Nissan or Renault vehicles. Factory systems range from simple four-speaker arrangements to multi-channel Rockford Fosgate, Yamaha and other premium systems with dedicated amplifiers, subwoofers and factory signal processing.

The Mitsubishi category on Focal Australia currently contains:

  • IS RNS 165 component speakers
  • IC RNS 165 coaxial speakers
  • IW REN YISO amplifier harness
  • HILO V3 high-to-low-level converter

These four products do not form a complete Mitsubishi-specific range for Triton, Outlander, Pajero Sport and the wider Australian Mitsubishi fleet.

IS RNS 165 and IC RNS 165 are Renault-format Focal Inside products. They may have applications in particular Renault-derived Mitsubishi vehicles where the mounting, connector, depth and electrical requirements match. IW REN YISO is a Renault/Dacia-format harness intended for selected installations using the Focal Impulse 4.320 amplifier. HILO V3 is a universal signal converter.

For many popular Australian Mitsubishi vehicles, the appropriate approach is a professionally tailored installation using a compatible Focal range, suitable mounting adaptors, correct wiring, amplification where required, digital signal processing and acoustic treatment.

That is not a disadvantage. A custom system provides access to a much broader selection of Focal products and can be designed around the vehicle, listening goals, touring requirements and budget. It simply must not be represented as a universal no-modification Plug & Play package.

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

Yes. Most Mitsubishi factory audio systems can be improved, but the degree of modification and the correct products vary considerably.

A suitable upgrade may include:

  • Replacement front component speakers
  • Replacement rear coaxial or component speakers
  • Improved tweeters
  • A compact four-channel amplifier
  • A multi-channel amplifier with DSP
  • A powered or passive subwoofer
  • A custom subwoofer enclosure
  • Focal BAM acoustic treatment
  • Vehicle-specific or custom-made mounting adaptors
  • Professionally terminated connector leads
  • Measurement and acoustic tuning

Potential improvements include:

  • Clearer vocals and dialogue
  • Better instrument separation
  • More natural midrange
  • Smoother and more detailed treble
  • Stronger mid-bass
  • Reduced distortion at higher volume
  • Improved front soundstage
  • Deeper and more controlled bass
  • Better clarity over road, tyre and diesel-engine noise

Before recommending equipment, an installer should identify:

  • Exact Mitsubishi model and generation
  • Build month and year
  • Chassis or model code
  • Australian-delivered or imported specification
  • Body style and cabin configuration
  • Factory speaker count
  • Factory amplifier
  • Rockford Fosgate, Yamaha or another branded system
  • Original speaker impedance
  • Original speaker dimensions and mounting depth
  • Factory connector type
  • Source-signal frequency range
  • Factory equalisation and crossover filtering
  • Telephone, navigation and warning-sound routing
  • Previous audio modifications

A nominally 165mm speaker is not automatically compatible with a factory 165mm location. Basket shape, mounting-hole pattern, depth, window clearance, grille clearance, sealing, connector design and impedance can all prevent a correct installation.

2. Does Focal offer a dedicated Mitsubishi Plug & Play range?

Not as a broad current range covering the major Australian Mitsubishi models.

The live Focal Inside brand selector does not currently present Mitsubishi as a selectable brand. The Focal Australia Mitsubishi category instead cross-lists selected products associated primarily with Renault-format applications.

This distinction matters.

A genuine vehicle-specific application normally confirms:

  • Exact vehicle generation
  • Compatible production period
  • Intended speaker location
  • Mounting pattern
  • Installation depth
  • Connector arrangement
  • Electrical compatibility
  • Factory-audio limitations
  • Required accessories

The presence of a product in a broad brand category is not enough on its own to establish all of those points.

The currently displayed IS RNS 165 and IC RNS 165 can be considered potential direct-fit options for specifically confirmed Renault-derived Mitsubishi platforms. They must not be promoted as dedicated kits for Mitsubishi Triton, Pajero Sport, Outlander or older Australian ASX models without supporting fitment documentation.

For vehicles without a confirmed application, Focal still offers several useful system paths:

  • Auditor or Universal for cost-conscious custom upgrades
  • Access and Slatefiber for stronger everyday performance
  • Flax Evo for refined tonal balance and natural vocals
  • K2 Power and K2 Power M for high-output systems
  • Utopia M for uncompromising custom installations
  • Compact Focal amplifiers and DSP solutions
  • Specialised active and passive subwoofers
  • BAM acoustic treatment

The right description is therefore “Focal Mitsubishi audio solutions” rather than a blanket claim that every displayed product is a Mitsubishi Plug & Play kit.

3. Which Mitsubishi models currently have the clearest Focal Inside-style applications?

The clearest current category applications are limited to Mitsubishi vehicles derived from Renault platforms.

Mitsubishi Express

The Australian Mitsubishi Express sold from 2020 was closely related to the Renault Trafic. The category lists IS RNS 165 and IC RNS 165 for this application.

Production and registration dates should be handled carefully. Australian sales began in 2020 and production ended in 2022, although a vehicle may have been registered later. The table should state the relevant build period rather than implying that every vehicle first registered in 2023 is necessarily a separate supported model year.

New-generation Mitsubishi ASX

The Renault-derived ASX was introduced in Europe from 2023. The equivalent new-generation ASX reached Australia later as an MY26 vehicle. An Australian page should not simply use the European 2023– date because this can be confused with the previous Mitsubishi-designed ASX that remained on sale locally.

IS RNS 165, IC RNS 165 and selected Renault-format integration accessories may be relevant to a confirmed new-generation ASX. Exact Australian head-unit, speaker and factory-audio specifications must still be checked.

Later Mitsubishi Colt

The later European Colt is closely related to the Renault Clio. It is not a current mainstream Australian-market model. It may remain in an international or imported-vehicle compatibility resource, but it should be labelled clearly as a European/imported application rather than presented as part of the normal Australian Mitsubishi range.

The Colt E 2026– entry should be removed unless Focal can provide a current application document. A row containing only IW REN YISO and no confirmed speakers does not establish a complete Mitsubishi audio solution.

4. Why do Renault-format Focal speakers appear in a Mitsubishi category?

Modern automotive groups increasingly share platforms, electrical systems and infotainment components.

Mitsubishi participates in the Renault–Nissan–Mitsubishi Alliance. Some newer Mitsubishi vehicles sold in particular regions are based closely on Renault products. Examples include:

  • Mitsubishi Express and Renault Trafic
  • Later Mitsubishi ASX and Renault Captur
  • Later European Mitsubishi Colt and Renault Clio

That relationship can make Renault-format Focal products relevant to a Mitsubishi carrying substantially shared hardware.

It does not mean that every Mitsubishi can use a Renault speaker or harness.

The following vehicles must not be grouped together merely because they use the same Mitsubishi model name:

  • Previous Australian ASX and new Renault-derived ASX
  • Older Mitsubishi Colt and later Renault-derived Colt
  • Older Mitsubishi Express generations and 2020–2022 Renault-derived Express

Likewise, membership of the same automotive alliance does not prove compatibility between:

  • Mitsubishi Outlander and Nissan X-Trail
  • Mitsubishi Triton and Nissan Navara
  • Mitsubishi Pajero Sport and another alliance SUV

Even when two vehicles share a platform, they can use different:

  • Door trims
  • Speaker brackets
  • Connectors
  • Speaker impedances
  • Factory amplifiers
  • Head units
  • software configurations
  • active crossovers
  • warning-sound routing
  • premium audio packages

The shared-platform relationship is a reason to investigate a product, not a substitute for confirming it.

5. Can a Mitsubishi Triton speaker system be upgraded?

Yes. Triton is one of the most valuable Mitsubishi audio-upgrade opportunities in Australia, but the current Mitsubishi category does not show a dedicated Triton Focal Inside kit.

Different Triton generations and cab configurations require separate assessment, including:

  • MN Triton
  • MQ Triton
  • MR Triton
  • MV Triton
  • Single Cab
  • Club Cab
  • Double Cab
  • GLX, GLX+, GLX-R, GLS and GSR variants

The available rear speaker positions and cabin volume differ between Single Cab, Club Cab and Double Cab models. Factory speaker counts can also vary by variant.

A tailored Triton system may include:

  • Front component speakers
  • Rear coaxial speakers where fitted
  • An amplifier beneath a seat or behind trim
  • A compact under-seat powered subwoofer
  • A custom enclosure behind the rear seat
  • DSP correction for the factory source
  • BAM treatment around front and rear speaker locations

Triton installations should consider:

  • Diesel-engine and tyre noise
  • Corrugated-road vibration
  • Water and dust exposure
  • Bullbars, driving lights and UHF equipment
  • Dual-battery and solar systems
  • Canopies and touring accessories
  • Seat travel and storage space
  • Off-road use
  • Service access

A more powerful speaker is not automatically better when driven by an unamplified factory head unit. Sensitivity, impedance and the available factory signal must be matched to the proposed system.

For a simple upgrade, efficient Focal speakers with correct adaptors and sealing may provide a worthwhile improvement. For stronger output and bass, a compact amplifier, DSP and subwoofer are usually more effective than replacing speakers alone.

6. Can a Pajero or Pajero Sport audio system be upgraded?

Yes. Pajero and Pajero Sport vehicles are suitable for anything from a straightforward speaker replacement to a comprehensive touring audio system.

These are separate model families and must not be treated as one vehicle.

Potential applications include:

  • Pajero NM, NP, NS, NT, NW and NX
  • Pajero Sport QE and QF
  • Earlier Challenger models
  • Standard factory audio
  • Factory-amplified or branded premium systems

Some vehicles use simple factory speaker arrangements. Others may include additional tweeters, more speaker channels, rear entertainment or Rockford Fosgate equipment. A premium badge changes the integration strategy because the original amplifier may apply channel-specific filtering, equalisation and impedance requirements.

A Pajero or Pajero Sport upgrade may involve:

  • Front component speakers
  • Rear door speakers
  • Replacement or retention of factory tweeters
  • Retention of selected factory channels
  • A DSP interface
  • Additional amplification
  • A cargo-area or side-panel subwoofer
  • A removable enclosure for touring flexibility
  • Tailgate and door acoustic treatment

The system should be designed around how the vehicle is used. A seven-seat family vehicle has different subwoofer-space requirements from a two-row touring build with drawers, a fridge and recovery gear.

Trim removal must also account for side airbags, seat-belt mechanisms, rear air conditioning, factory wiring and 4WD accessories. After installation, all infotainment, navigation, camera, parking and warning functions should be retested.

7. Can an Outlander or Outlander PHEV sound system be upgraded?

Yes, but the exact generation and factory system are critical.

Outlander has been sold across several generations with different dashboards, speakers, amplifiers and premium-audio options. The current generation also shares underlying architecture with alliance vehicles, but that does not automatically make a Nissan speaker kit or harness compatible.

An Outlander upgrade may include:

  • Front component speakers
  • Rear coaxial or component speakers
  • Retention or replacement of selected factory tweeters
  • DSP integration
  • Additional amplification
  • A compact boot-area subwoofer
  • A side enclosure or removable enclosure
  • Door and cargo-area acoustic treatment

Outlander PHEV requires additional precautions around:

  • High-voltage cables
  • Traction battery equipment
  • Charging hardware
  • Battery cooling and ventilation
  • Power electronics
  • Emergency isolation points
  • Vehicle sleep and wake behaviour
  • Manufacturer service access

No audio component or cable should obstruct high-voltage identification, battery ventilation, service covers or emergency equipment.

Later vehicles can also use sophisticated premium systems. International 2026 Outlander material documents Yamaha systems with dedicated DSP, multiple speakers and amplification. Australian specification and trim level must be confirmed rather than inferred from an overseas brochure.

A premium Yamaha system is not a suitable target for a basic Y-ISO amplifier harness. The installer should measure the factory signal, identify each channel, verify impedance and determine whether to retain the factory amplifier, integrate after it or replace selected parts of the architecture.

8. Can an ASX or Eclipse Cross speaker system be upgraded?

Yes, but the ASX model name now covers fundamentally different vehicles.

Previous Australian ASX

The long-running Mitsubishi-designed ASX sold in Australia before the new Renault-derived model must be treated as a separate application. Higher variants were available with Rockford Fosgate premium audio, while other versions used simpler factory systems.

The current category’s ASX 2023– RNS listing should not be applied to this previous Australian generation simply because the badge is the same.

A previous-generation ASX may suit a custom Focal installation using:

  • Vehicle-specific aftermarket adaptors
  • Component front speakers
  • Coaxial rear speakers
  • A compact amplifier
  • DSP where factory equalisation is significant
  • A powered or passive subwoofer
  • Door and cargo-area BAM treatment

New-generation Australian ASX

The MY26 Australian ASX is related to the Renault Captur. This makes IS RNS 165, IC RNS 165 and selected Renault-format accessories plausible options, subject to exact Australian confirmation.

The installation still needs checks for:

  • Exact variant
  • Factory speaker count
  • Head-unit connector
  • Factory amplifier or premium system
  • Speaker positions
  • Mounting depth
  • Original impedance
  • Australian production specification

Eclipse Cross

Eclipse Cross is a separate Mitsubishi platform and is not covered merely because another Mitsubishi SUV appears in the category. Petrol and PHEV variants may also require different planning. A custom Focal system can be developed after physical and electrical inspection.

9. Can a Lancer, Lancer Evolution, Mirage, Magna or older Colt be upgraded?

Yes. Older Mitsubishi passenger cars can often be upgraded effectively because many use conventional speaker locations and simpler electrical systems.

Potential vehicles include:

  • Lancer CJ and earlier generations
  • Lancer Evolution models
  • Mirage hatch and sedan
  • Magna and Verada
  • Mitsubishi 380
  • Older Colt generations
  • Grandis
  • Delica imports

Compatibility must still be confirmed by generation and body style.

Older vehicles may require:

  • New speaker mounting adaptors
  • Replacement of brittle factory connectors
  • Repairs to damaged moisture barriers
  • New speaker cable in selected systems
  • Treatment of loose door trims
  • Replacement of failed factory amplifiers
  • Source-unit or signal-converter integration

Lancer Evolution and other performance vehicles can have substantial road, tyre and exhaust noise. A system that sounds balanced while parked may lose vocal and mid-bass clarity at motorway speed. Sensible acoustic treatment and adequate clean amplifier power can be as important as the speaker range.

An imported Delica or Japanese domestic-market vehicle may have a different head unit, speaker count, amplifier and connector layout from an Australian-delivered model. The chassis code and physical system should be inspected before ordering components.

The later European Colt listed with RNS products must not be confused with an older Australian or Japanese Colt. Shared model names do not establish shared audio architecture.

10. What is the difference between IS RNS 165, IC RNS 165, IW REN YISO and HILO V3?

Each product has a different role.

IS RNS 165

IS RNS 165 is a 165mm two-way component kit. It includes separate woofers and tweeters for compatible locations that provide or can accommodate separate high-frequency drivers.

Key published specifications include:

  • 60 watts nominal power
  • 120 watts maximum power
  • 4-ohm nominal impedance
  • 92.7dB sensitivity
  • Polyglass woofer cone
  • Aluminium inverted-dome tweeter

IC RNS 165

IC RNS 165 is a 165mm two-way coaxial kit. Its tweeter is integrated into the speaker assembly, making it suitable for compatible locations without a separate tweeter position.

Key published specifications include:

  • 60 watts nominal power
  • 120 watts maximum power
  • 4-ohm nominal impedance
  • 92dB sensitivity
  • Woven glass-fibre cone
  • Adjustable aluminium inverted-dome tweeter

IW REN YISO

IW REN YISO is an integration harness designed around selected Renault/Dacia factory head units and the Focal Impulse 4.320 amplifier system.

It is not:

  • A speaker adaptor
  • A complete amplifier kit
  • A universal Mitsubishi harness
  • A solution for every factory head unit
  • Automatically compatible with factory amplification
  • Automatically compatible with Rockford Fosgate or Yamaha audio

A complete amplifier installation may require the amplifier, extension cable, fused power wiring and other accessories in addition to the Y-harness.

HILO V3

HILO V3 is a universal high-to-low-level converter. It can help derive an RCA-level signal from a compatible factory speaker output for an aftermarket amplifier.

It is not a Mitsubishi-specific Plug & Play kit. The source channel must provide the required frequency range, voltage and behaviour. A converter cannot restore bass or treble information that the factory system has removed from the selected channel.

11. Can a Mitsubishi Rockford Fosgate or Yamaha system be upgraded?

Potentially, but premium factory systems require a different process from standard non-amplified audio.

Mitsubishi has offered Rockford Fosgate systems in vehicles such as selected ASX, Outlander, Pajero and other variants. More recent international Outlander specifications also include Yamaha systems with dedicated digital signal processing, multiple amplifiers and model-specific speakers.

A branded premium system may include:

  • Low-impedance speakers
  • Dedicated multi-channel amplification
  • Active crossover filtering
  • Factory equalisation
  • Centre or surround channels
  • A factory subwoofer
  • Speed-dependent processing
  • Listening-position modes
  • Noise compensation
  • Vehicle-specific door construction

Before replacing any component, the installer should measure:

  • Original speaker impedance
  • Output voltage from the factory amplifier
  • Frequency range supplied to each channel
  • Crossover points
  • Signal polarity
  • Factory equalisation
  • Volume-dependent processing
  • Bass roll-off
  • Telephone and navigation routing
  • Parking and warning-sound routing

A four-ohm aftermarket speaker should not automatically replace a lower-impedance factory driver. It may play too quietly, alter the tonal balance or present an unsuitable load depending on how the system is designed.

The best strategy may be to retain the factory source and amplifier while replacing only confirmed compatible speakers. In other cases, a DSP interface and new amplification may be required. Replacing every speaker is not automatically the most effective or economical approach.

IW REN YISO and Impulse 4.320 must not be assumed compatible with a Rockford Fosgate, Yamaha or other factory-amplified system.

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

Not every upgrade requires both.

Efficient, electrically compatible Focal speakers can provide a useful improvement from a standard factory head unit. This may suit an owner seeking clearer vocals, smoother treble and better moderate-volume performance without building a larger system.

An amplifier can provide:

  • Greater clean volume
  • Increased headroom
  • Better control of the speaker cone
  • Stronger mid-bass
  • Improved dynamics
  • Reduced clipping
  • Power for an additional subwoofer

A DSP can allow the installer to:

  • Measure the factory signal
  • Correct selected factory equalisation
  • Set crossover frequencies
  • Adjust time alignment
  • Balance speaker levels
  • Improve stereo imaging
  • Integrate a subwoofer
  • Create driver-focused tuning
  • Store alternative tuning presets

DSP is particularly useful when the factory source applies strong equalisation, all-pass filters, channel delays, bass roll-off or active crossover filtering.

It has limits. A DSP cannot recreate frequency content that is completely absent from all available input channels. The installer may need to combine multiple channels or use an appropriate vehicle interface to obtain a usable full-range signal.

The Focal Impulse 4.320 can be useful in a compatible standard non-amplified application. A Y-harness must match the exact head unit and connector. Fused battery power, grounding, cable routing, ventilation and safe mounting must also be addressed.

13. Can a subwoofer be added to a Mitsubishi?

Yes. A properly integrated subwoofer is often the most effective way to add low-frequency depth and impact.

Potential Focal solutions include:

  • ISUB ACTIVE
  • ISUB ACTIVE 2.1
  • ISUB TWIN
  • PSB200
  • Compact sealed enclosures
  • Vehicle-side enclosures
  • Behind-seat ute enclosures
  • Removable cargo-area enclosures
  • Custom fibreglass or timber enclosures

The right solution depends on:

  • Vehicle and body style
  • Available space
  • Required output
  • Factory signal
  • Existing amplifier
  • Seat travel
  • Seven-seat use
  • Drawer and fridge systems
  • Touring equipment
  • Cargo access
  • Hybrid or PHEV equipment
  • Electrical capacity

A Triton may prioritise an under-seat or behind-seat solution. An Outlander or Pajero Sport may need to retain all seating positions and cargo access. A Lancer sedan may provide more flexibility for a boot enclosure.

Correct integration requires:

  • A suitable input signal
  • Appropriate crossover frequency
  • Level matching
  • Phase and polarity adjustment
  • Time alignment where available
  • Secure mounting
  • Correct fused power wiring
  • Ventilation for active electronics

Connecting a subwoofer to a factory channel with aggressive bass roll-off can produce disappointing results. The input signal must be measured before the installation is designed.

14. Can Focal BAM treatment improve a Mitsubishi used for commuting or touring?

Yes. Strategic acoustic treatment can materially improve clarity, mid-bass control and resistance to rattles.

Mitsubishi vehicles used for work, touring and off-road travel may experience:

  • Road and tyre noise
  • Diesel-engine noise
  • Door-panel resonance
  • Tailgate vibration
  • Cargo-area resonance
  • Canopy and accessory vibration
  • Loose trim on rough roads
  • Speaker energy escaping through the door structure

Focal BAM treatment may help:

  • Strengthen the speaker mounting environment
  • Reduce selected panel resonance
  • Improve mid-bass response
  • Reduce energy loss behind the speaker
  • Reduce specific rattles
  • Improve clarity at highway speed
  • Create a more controlled door cavity

Useful treatment areas may include:

  • Front doors
  • Rear doors
  • Speaker mounting surfaces
  • Outer door skins
  • Tailgate
  • Rear quarter panels
  • Cargo-area panels
  • Custom subwoofer enclosures

Treatment must not interfere with:

  • Door drainage
  • Window mechanisms
  • Locks and latches
  • Side airbags
  • Pressure sensors
  • Seat-belt mechanisms
  • Factory wiring
  • Vehicle-control modules
  • Battery ventilation
  • High-voltage equipment
  • Service access
  • Identification and warning labels

Covering every visible surface can add unnecessary weight and cost. The best approach targets speaker locations, confirmed resonant panels and known vibration points.

In a work ute or touring 4WD, equipment should also be secured for corrugations, water crossings and cargo impact. Installation materials must suit the vehicle’s real operating environment, not merely a showroom demonstration.

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

Begin with complete vehicle information.

Provide the dealer with:

  • Exact Mitsubishi model
  • Chassis or model code
  • Build month and year
  • Vehicle Identification Number
  • Australian-delivered or imported specification
  • Body style and cab configuration
  • Trim level
  • Factory speaker count
  • Rockford Fosgate, Yamaha or standard audio
  • Factory amplifier location
  • Factory subwoofer
  • Original head unit
  • Previous audio modifications
  • Petrol, diesel, hybrid, PHEV or electric drivetrain
  • Touring accessories and electrical equipment
  • Required seating and cargo space
  • Listening preferences
  • Desired performance
  • Available budget

Physical compatibility can be affected by:

  • Speaker diameter
  • Basket shape
  • Mounting-hole pattern
  • Installation depth
  • Magnet clearance
  • Window clearance
  • Grille clearance
  • Factory connector
  • Required spacer or adaptor
  • Door sealing
  • Tweeter location

Electrical and acoustic compatibility can be affected by:

  • Original impedance
  • Factory amplifier
  • Active crossover filtering
  • Factory equalisation
  • Signal voltage
  • Signal polarity
  • Bass roll-off
  • Telephone and navigation routing
  • Warning-sound routing
  • Vehicle sleep and wake behaviour
  • Hybrid and high-voltage architecture

The final cost depends on:

  • Number and type of speakers
  • Vehicle-specific or custom mounting
  • Wiring adaptors
  • Acoustic treatment
  • Amplifier
  • DSP integration
  • Subwoofer
  • Interior disassembly
  • Custom fabrication
  • Measurement and tuning time

A front-speaker upgrade in a standard-audio Triton will usually be less complex than rebuilding a factory-amplified Rockford Fosgate system or integrating amplification and bass into an Outlander PHEV.

It would be misleading to publish one standard Mitsubishi audio-upgrade price without identifying the vehicle and factory system.

Upgrade Your Mitsubishi with Focal Sound

Whether you drive a Triton, Pajero Sport, Pajero, Outlander, Outlander PHEV, ASX, Eclipse Cross, Lancer, Mirage, Express, Colt, Delica or another Mitsubishi, a professionally designed Focal system can improve clarity, dynamics and bass while retaining the vehicle’s practical character.

Selected Renault-derived Mitsubishi vehicles may suit products such as:

  • IS RNS 165
  • IC RNS 165
  • IW REN YISO in a correctly confirmed amplifier installation

Other Mitsubishi vehicles may be better served by a tailored system using:

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

Particular care is required with:

  • Rockford Fosgate systems
  • Yamaha systems
  • Factory amplification
  • Low-impedance speakers
  • Active crossovers
  • New and previous ASX generations
  • Shared Renault or Nissan platforms
  • Imported vehicles
  • PHEV and high-voltage equipment
  • Work-ute and touring accessories
  • Factory warning sounds
  • Vehicle sleep behaviour

A correct system begins with identifying the exact vehicle and factory audio architecture. Review the Mitsubishi product options or contact an Authorised Focal Australia Dealer for compatibility confirmation, professional installation and system tuning.
