MERCEDES-BENZ

Upgrade your Mercedes-Benz 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 A-Class, C-Class, E-Class and more, using original mounting points and plug-in connectors so there is no cutting, no splicing and no permanent modification to the cabin. Installation is clean, fast and fully reversible, preserving the premium look and refinement of your Mercedes-Benz interior.

By replacing the standard speakers with high-performance Focal drivers, these Plug & Play kits deliver a more detailed and dynamic soundstage, with clearer vocals, stronger mid-bass and smoother, more extended highs than the factory audio system can provide. You keep your original head unit, COMAND / MBUX integration, steering wheel controls and safety features, while enjoying a genuine premium sound upgrade every time you drive.

The attached table shows all vehicles that currently have a compatible Focal Inside system available. For exact speaker, subwoofer and amplifier options, please use the Focal Inside Configurator or contact your nearest Authorised Focal Dealer.

MERCEDES-BENZ Compatibility Guide

Installation and Compatibility Notes:

  • Compatibility information provided is intended as a general guide only and may vary depending on your vehicle's model year, build date, trim level, country of origin, factory audio system, optional equipment and other vehicle specifications.
  •  If a Focal plug & play harness and amplifier is listed for your vehicle, it is designed for non-factory amplified audio systems only and is not compatible with factory amplified systems. 
  • Focal plug & play harnesses are designed for use with the original factory head unit. If your vehicle has an aftermarket head unit installed, alternative wiring adaptors or a conventional wiring kit may be required.
  • Compatibility should always be confirmed by an Authorised Focal Australia Dealer prior to purchase or installation to ensure the correct products are selected for your specific vehicle.
  • Professional installation by an Authorised Focal Australia Dealer is strongly recommended to achieve the best performance, ensure correct fitment and maintain product warranty.
  • Focal inside Mercedes speakers and subwoofers may suit Burmester factory Mercedes audio, but do not support the Focal Impulse amplifier.
  • Some models may require adapters “KIAC1175” for speaker replacement. 
  • If your Mercedes is between 2021 - 2023 it is important to check compatibility with your authorised Focal dealer.

More Brand Information

Mercedes-Benz is a German luxury and performance vehicle brand that traces its origin to 1886, when Carl Benz patented the Benz Patent-Motorwagen in Mannheim and Gottlieb Daimler developed early motorised vehicles in Germany as well—work widely treated as the birth of the modern automobile. The modern Mercedes-Benz brand identity formed through consolidation: the famous three-pointed-star trademark in a laurel wreath was created in 1925, and in 1926 the companies Benz & Cie. and Daimler-Motoren-Gesellschaft merged to become Daimler-Benz, adopting Mercedes-Benz as the unified vehicle brand. In SEO terms, Mercedes-Benz is most strongly associated with German engineering, luxury sedans, premium SUVs, and high-performance Mercedes-AMG models, plus commercial vehicles like Mercedes-Benz vans. The range is famous for combining refinement with real-world performance—think C-Class, E-Class, S-Class, GLC, GLE, G-Class, and workhorses like the Sprinter as core “high intent” keywords.

Mercedes-Benz also owns a long list of safety and technology firsts that still drive search demand. It highlights ABS reaching series production in 1978, and the driver’s airbag with belt tensioner in 1981—milestones that reinforce Mercedes as a safety-led innovator. For traction and touring capability, 4MATIC all-wheel drive debuted in 1987, becoming a key keyword for wet-weather confidence and grip. On the software side, Mercedes introduced MBUX (Mercedes-Benz User Experience) in 2018, pushing the brand deeper into connected infotainment and voice-style control—an increasingly important “luxury tech” search driver. Globally, Mercedes-Benz has strongest demand across major premium markets including Germany, China, and the United States. Its stated purpose for the brand is “First move the world” — essentially: keep leading in luxury, safety, performance and digital innovation while taking sustainability seriously as part of how the company operates.

Speaker and Car Audio Upgrade FAQs

A professionally selected Mercedes-Benz speaker upgrade can improve vocal clarity, tonal balance, stereo imaging and bass performance while retaining the original interior, infotainment system and vehicle controls.

Focal Australia offers a genuine range of vehicle-specific Focal Inside products for selected Mercedes-Benz vehicles.

Depending on the exact model, chassis code, production date and factory audio system, a compatible upgrade may include:

  • Focal component speakers
  • Focal coaxial speakers
  • A dedicated centre-channel speaker
  • Dedicated surround speakers
  • Right-hand-drive Mercedes-Benz subwoofers
  • Vehicle-specific mounting adaptors
  • Plug & Play wiring
  • Compact amplification for selected Standard audio systems
  • Digital signal processing
  • Additional compact subwoofer integration
  • Focal BAM acoustic treatment
  • Professional measurement and tuning

The available Mercedes-Benz Focal Inside range includes:

  • IS MBZ 100 component speakers
  • IC MBZ 100 coaxial speakers
  • ICC MBZ 100 centre-channel speaker
  • ICR MBZ 100 surround speakers, subject to availability
  • ISUB MBZ 2 RHD subwoofers
  • IS MBZ 100 V2 component speakers
  • IC MBZ 100 V2 coaxial speakers
  • ISUB MBZ 2 RHD V2 subwoofers
  • KIAC1175 Mercedes-Benz adaptor and crossover kit
  • IW MBZ YISO amplifier harness for selected applications
  • Impulse 4.320 amplifier for specifically listed non-amplified systems

These products are not universally compatible with every Mercedes-Benz carrying the same model name.

Mercedes-Benz may change speaker dimensions, connectors, factory amplification and signal processing during a model generation. The Standard, Advanced, Burmester, Burmester 3D and Burmester High-End 4D systems within the same model family can also require very different upgrade strategies.

Compatibility must therefore be confirmed using the exact vehicle rather than the broad model name alone.

1. Can a Mercedes-Benz factory audio system be upgraded with Focal?

Yes. Focal offers dedicated Mercedes-Benz products for a considerable number of compatible vehicles.

A correctly selected and installed system may provide:

  • Clearer vocals
  • Improved instrument separation
  • Smoother treble
  • Stronger midrange definition
  • More focused stereo imaging
  • Improved soundstage height
  • Better bass extension
  • Improved bass control
  • Reduced distortion
  • Greater clean listening volume
  • More balanced sound throughout the cabin

The level of improvement depends on:

  • Exact Mercedes-Benz model
  • Chassis code
  • Production month and year
  • Body style
  • Factory audio package
  • Speaker positions being upgraded
  • Factory amplifier
  • Original speaker impedance
  • Available source signal
  • Amplification
  • Subwoofer integration
  • Installation quality
  • Final tuning

Before recommending products, the installer should identify:

  • Vehicle Identification Number
  • Australian-delivered or imported specification
  • Standard or premium factory audio
  • Burmester branding
  • Original speaker count
  • Existing centre speaker
  • Existing surround speakers
  • Original bass drivers
  • Factory amplifier
  • COMAND or MBUX generation
  • Previous audio modifications
  • Relevant vehicle software version

A speaker being advertised for Mercedes-Benz does not mean it fits every Mercedes-Benz model or every speaker position.

2. Is there a dedicated Mercedes-Benz Focal Inside Plug & Play range?

Yes.

Focal offers one of its more comprehensive vehicle-specific ranges for selected Mercedes-Benz vehicles.

Original Mercedes-Benz Range

The original-generation range includes:

  • IS MBZ 100 component speakers
  • IC MBZ 100 coaxial speakers
  • ICC MBZ 100 centre-channel speaker
  • ICR MBZ 100 surround speakers
  • ISUB MBZ 2 RHD subwoofers

These products are listed for selected previous-generation platforms such as:

  • C-Class W205
  • E-Class W213
  • S-Class W222
  • GLC X253 and C253
  • Selected CLS applications
  • Selected EQC applications
  • Selected V-Class and EQV applications
  • Selected Mercedes-AMG applications

V2 Mercedes-Benz Range

The later-generation V2 range includes:

  • IS MBZ 100 V2 component speakers
  • IC MBZ 100 V2 coaxial speakers
  • ISUB MBZ 2 RHD V2 subwoofers

These products are intended for selected later-generation platforms, including applications within:

  • C-Class W206
  • E-Class W214
  • CLE C236 and A236
  • GLC X254 and C254
  • S-Class W223
  • EQE
  • EQS
  • Other specifically listed newer Mercedes-Benz vehicles

The original and V2 products must not be interchanged simply because both use a 100mm nominal speaker description.

Differences may include:

  • Speaker-frame dimensions
  • Mounting-hole pattern
  • Connector design
  • Installation depth
  • Factory enclosure
  • Grille clearance
  • Signal processing
  • Speaker impedance
  • Required crossover
  • Subwoofer location
  • Left-hand-drive or right-hand-drive configuration

For Australian vehicles, the appropriate RHD subwoofer version must be selected.

3. Which Mercedes-Benz models may be compatible with Focal Inside?

Focal Inside compatibility is available for selected vehicles within several Mercedes-Benz model families.

Potentially supported model groups include:

  • Mercedes-Benz C-Class
  • Mercedes-Benz E-Class
  • Mercedes-Benz CLE
  • Mercedes-Benz S-Class
  • Mercedes-Benz CLS
  • Mercedes-Benz GLC
  • Mercedes-Benz GLE
  • Mercedes-Benz G-Class
  • Mercedes-Benz EQC
  • Mercedes-Benz EQE
  • Mercedes-Benz EQE SUV
  • Mercedes-Benz EQS
  • Mercedes-Benz EQS SUV
  • Mercedes-Benz V-Class
  • Mercedes-Benz EQV
  • Mercedes-Benz Marco Polo
  • Selected Mercedes-AMG models

Some vehicles may support a complete system involving front, rear, centre and bass upgrades.

Others may support only:

  • A centre-channel replacement
  • Selected front speakers
  • Selected rear speakers
  • Surround speakers
  • A subwoofer pair
  • A partial system using adaptors
  • A professionally customised installation

Certain Mercedes-Benz models listed in a compatibility document may include notes such as:

  • Factory woofer not managed
  • Three-way system not fully supported
  • Centre speaker only
  • Burmester version only
  • Specific adaptor required
  • Production-date restriction
  • No compatible 165mm woofer
  • Amplifier harness not supported

These notes describe limitations, not complete vehicle compatibility.

The dealer should match:

  • Model name
  • Chassis code
  • Body code
  • Production date
  • Factory audio package
  • Intended speaker position
  • Left-hand-drive or right-hand-drive configuration

A W205 C-Class and W206 C-Class require different products. The same applies to W213 and W214 E-Class vehicles and to X253 and X254 GLC models.

4. What is the difference between the Mercedes-Benz Focal speakers?

Each Focal Mercedes-Benz product performs a particular role.

IS MBZ 100 and IS MBZ 100 V2

These are component speaker kits.

They combine:

  • Separate Flax-cone midrange drivers
  • Separate aluminium inverted-dome tweeters
  • Dedicated filtering
  • Vehicle-specific mounting and connections

A component kit is intended for a factory position with separate midrange and tweeter locations.

Potential benefits include:

  • Improved soundstage height
  • Clearer vocals
  • More natural midrange
  • Increased treble detail
  • Better instrument separation
  • Improved stereo imaging

IC MBZ 100 and IC MBZ 100 V2

These are coaxial speaker kits.

The tweeter is incorporated into the speaker assembly, making the kit suitable for compatible positions that do not provide a separate factory tweeter location.

They may be used for selected:

  • Rear doors
  • Rear side panels
  • Coaxial factory locations
  • Secondary listening positions

ICC MBZ 100

The ICC MBZ 100 is a dedicated Mercedes-Benz centre-channel speaker.

Its purpose is to improve:

  • Dashboard-level vocal reproduction
  • Centre-stage clarity
  • Midrange definition
  • Integration with the original multi-channel system

The ICC MBZ 100 was also developed to retain compatible Mercedes-Benz eCall emergency-call operation.

It must only be installed where specifically listed. A centre-channel speaker may reproduce music, telephone audio, navigation prompts, emergency-call audio or other vehicle information.

ICR MBZ 100

The ICR MBZ 100 is a dedicated surround coaxial speaker for compatible Mercedes-Benz surround locations.

It should not automatically be substituted for an ordinary front or rear speaker.

Availability should be confirmed because international production status and Australian stock may differ.

ISUB MBZ 2 RHD and ISUB MBZ 2 RHD V2

These products contain a matched pair of subwoofers designed for selected right-hand-drive Mercedes-Benz vehicles.

The original and V2 versions serve different vehicle generations and are not interchangeable without confirmed compatibility.

5. Can a Mercedes-Benz C-Class or GLC be upgraded?

Selected C-Class and GLC vehicles have some of the most comprehensive Focal Inside Mercedes-Benz applications.

Previous-Generation C-Class and GLC

Selected C-Class W205 and GLC X253/C253 vehicles may use products including:

  • IS MBZ 100
  • IC MBZ 100
  • ICC MBZ 100
  • ICR MBZ 100
  • ISUB MBZ 2 RHD
  • IW MBZ YISO harness in specifically listed Standard audio vehicles
  • Impulse 4.320 amplifier where the harness and factory system are confirmed

The actual combination depends on:

  • Sedan, estate, coupé or cabriolet body
  • Production date
  • Standard or Burmester audio
  • Front or rear position
  • Original tweeter locations
  • Existing factory amplifier

Later-Generation C-Class and GLC

Selected C-Class W206 and GLC X254/C254 vehicles may use:

  • IS MBZ 100 V2
  • IC MBZ 100 V2
  • ICC MBZ 100
  • ISUB MBZ 2 RHD V2

The W206 sedan should not be confused with the CLE Coupé and Cabriolet.

Mercedes-Benz no longer uses a W206-based C-Class Coupé or Cabriolet. These body styles are covered by the separate CLE range.

A suitable system might involve:

  • Front component speakers
  • Rear component or coaxial speakers
  • Centre-channel replacement
  • RHD subwoofer pair
  • Retention of the original MBUX system
  • Additional DSP and amplification where professionally integrated

Factory audio configuration must still be confirmed before purchase.

6. Can an E-Class, CLE or S-Class audio system be upgraded?

Selected vehicles within these model families have listed Focal Inside applications.

E-Class W213

Selected W213-generation vehicles may support:

  • IS MBZ 100
  • IC MBZ 100
  • ICC MBZ 100
  • ICR MBZ 100
  • ISUB MBZ 2 RHD
  • IW MBZ YISO and Impulse amplification in limited compatible Standard audio applications

The W213 family includes different sedan, estate, coupé and cabriolet configurations. Product positions may differ between body styles.

E-Class W214

Selected W214-generation vehicles may use:

  • IS MBZ 100 V2
  • IC MBZ 100 V2
  • ICC MBZ 100
  • ISUB MBZ 2 RHD V2

CLE C236 and A236

The CLE is available as a two-door Coupé or Cabriolet.

Selected vehicles may use V2 Mercedes-Benz products, but the exact audio package and body style must be checked.

S-Class W222 and W223

Selected W222 applications may support products from the original Mercedes-Benz range, while selected W223 applications may use later V2 products.

S-Class audio systems can be particularly complex because they may include:

  • Numerous speaker channels
  • Burmester amplification
  • Active crossover filtering
  • Multiple centre and surround functions
  • Rear-seat entertainment
  • Seat-mounted audio components
  • Bass exciters
  • Dolby Atmos processing
  • Burmester 3D or High-End 4D audio
  • Vehicle-specific sound profiles

Replacing one speaker without measuring the channel may create an imbalance with the remaining system.

A complete S-Class upgrade requires specialist multi-channel integration and tuning.

7. Can GLE, G-Class and Mercedes-AMG systems be upgraded?

Potentially, but these applications often involve partial rather than complete Focal Inside coverage.

Mercedes-Benz GLE

Different GLE generations can use:

  • Conventional factory speakers
  • Three-way door systems
  • Dedicated centre speakers
  • Surround channels
  • Burmester amplification
  • Model-specific mounting arrangements

Selected later GLE vehicles may use ICC MBZ 100 speakers with the KIAC1175 adaptor and crossover kit in specific positions.

The factory woofer or complete three-way system may not be covered by the Focal application.

A GLE Coupé must be identified using its correct body code and must not be treated as identical to the GLE SUV.

Mercedes-Benz G-Class

Selected G-Class vehicles may support Focal midrange, tweeter, surround or centre-speaker upgrades.

Some applications do not provide a direct Focal replacement for every factory woofer.

The G-Class may also have:

  • Burmester audio
  • Door-mounted multi-way systems
  • Significant road and tyre noise
  • Off-road accessories
  • Auxiliary power equipment
  • Additional communication equipment

These factors affect product choice and tuning.

Mercedes-AMG

Mercedes-AMG vehicles must be checked by exact model and chassis.

The AMG GT two-door, AMG GT four-door and AMG SL are separate platforms.

They must not be grouped together based only on their AMG branding.

A compatible upgrade should preserve:

  • Original infotainment
  • Performance displays
  • Vehicle settings
  • Cameras
  • Parking information
  • Telephone functions
  • Navigation prompts
  • Audible warnings
  • Emergency-call functionality

8. Can Mercedes-EQ vehicles and Mercedes-Benz vans be upgraded?

Selected electric vehicles and vans have Focal applications, but these installations require additional planning.

Potentially supported electric models include selected:

  • EQC
  • EQE
  • EQE SUV
  • EQS
  • EQS SUV
  • EQA
  • EQV

However, a model appearing in a compatibility table does not necessarily mean that a complete speaker system is available.

Some vehicles may have:

  • Centre-speaker compatibility only
  • Rear-speaker compatibility only
  • No direct replacement for a larger factory woofer
  • A Burmester-only application
  • No supported amplifier harness
  • No direct Focal subwoofer replacement

Potential van applications include selected:

  • Citan
  • V-Class
  • Vito
  • eVito
  • EQV
  • Marco Polo

A van installation should consider:

  • Passenger or commercial trim
  • Sliding doors
  • Rear seating configuration
  • Cargo barriers
  • Shelving
  • Camper conversions
  • Auxiliary batteries
  • Solar systems
  • Inverters
  • Refrigeration equipment
  • Additional electrical accessories

In an electric vehicle, audio wiring and equipment must not interfere with:

  • High-voltage cables
  • Traction battery equipment
  • Battery cooling
  • Charging systems
  • Power electronics
  • Emergency isolation equipment
  • Manufacturer service access

After installation, the vehicle should be tested through start-up, shutdown, charging, sleep and restart cycles.

  • eCall and communication-audio routing

The number of speakers and factory amplifier design varies significantly between models.

Before replacing a Burmester speaker, the installer should measure:

  • Original speaker impedance
  • Amplifier output voltage
  • Frequency range supplied to the channel
  • Active crossover points
  • Signal polarity
  • Factory equalisation
  • Volume-dependent processing
  • Centre-channel content
  • Surround-channel content
  • Bass-channel content
  • Sound-profile behaviour
  • Telephone and navigation routing
  • eCall operation
  • Warning-sound routing

Selected Focal Mercedes-Benz speakers and RHD subwoofers may suit selected Burmester applications where specifically listed.

The Focal Impulse 4.320 and IW MBZ YISO harness must not be assumed compatible with Burmester or another factory-amplified premium system.

A suitable Burmester upgrade may involve:

  • Retaining the original infotainment
  • Retaining the original Burmester amplifier
  • Replacing selected compatible speakers
  • Retaining specialised factory speakers
  • Improving the primary front soundstage
  • Upgrading compatible factory bass drivers
  • Adding a signal-integration DSP
  • Adding carefully matched amplification
  • Professional acoustic measurement and tuning

Replacing every speaker is not automatically the best strategy.

10. Which Focal range is best for a Mercedes-Benz?

Focal Inside should be the first choice where a dedicated Mercedes-Benz product is confirmed.

Focal Inside

Potential benefits include:

  • Vehicle-specific mounting
  • Compatible factory-style connections
  • Use of original speaker locations
  • Clean interior appearance
  • Reduced installation modification

Utopia M

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

The most expensive speaker is not automatically the correct choice.

Selection should consider:

  • Available installation depth
  • Speaker diameter
  • Factory impedance
  • Source-signal quality
  • Amplifier power
  • Required crossover frequencies
  • Factory speaker locations
  • Listening position
  • Required volume
  • Installation complexity
  • Reversibility
  • Available budget

11. Can the original COMAND or MBUX system be retained?

In most modern Mercedes-Benz upgrades, retaining the original COMAND or MBUX system is the preferred approach.

Depending on the vehicle, the original infotainment system may manage:

  • Radio and media
  • Bluetooth
  • Telephone calls
  • Apple CarPlay
  • Android Auto
  • Navigation
  • Factory microphone
  • Voice control
  • Steering-wheel controls
  • Reversing camera
  • Surround-view cameras
  • Parking information

The Focal Impulse 4.320 may be used with the IW MBZ YISO harness only in specifically listed compatible Standard audio vehicles.

Compatibility may depend on:

  • Original factory head unit
  • Non-amplified audio configuration
  • Production date
  • Correct connector
  • Correct harness
  • Required power wiring
  • Available mounting location

It should not be assumed compatible with:

  • Burmester audio
  • Factory-amplified audio
  • Premium multi-channel audio
  • Aftermarket head units
  • Modified factory wiring
  • Vehicles outside the listed production range

A DSP can allow the installer to:

  • Measure the factory signal

  • Set crossover frequencies
  • Balance individual speakers
  • Adjust time alignment
  • Improve stereo imaging
  • Integrate a subwoofer
  • Manage centre and surround channels
  • Create a driver-focused tune
  • Create alternative listening presets

DSP may be especially valuable with Burmester, multi-channel and premium Focal installations.

A DSP cannot restore frequency information that is completely absent from the selected input channels.

13. Can a Mercedes-Benz subwoofer be upgraded?

Yes, in selected vehicles.

Focal offers dedicated right-hand-drive Mercedes-Benz subwoofer pairs for compatible Australian vehicles:

  • ISUB MBZ 2 RHD
  • ISUB MBZ 2 RHD V2

The correct version depends on the vehicle generation and factory bass locations.

Potential benefits include:

  • Deeper bass
  • Increased low-frequency impact
  • Improved bass definition
  • Reduced distortion
  • Better integration with the main speakers
  • Fuller sound at moderate volume

The RHD designation is important. A left-hand-drive subwoofer kit must not be supplied for an Australian right-hand-drive vehicle unless Focal has specifically documented the application.

Where a dedicated Mercedes-Benz subwoofer is unavailable, other potential Focal solutions include:

  • ISUB ACTIVE
  • ISUB ACTIVE 2.1

Crossover frequency, level, phase, polarity and signal delay must be tuned correctly.

14. Can Focal BAM acoustic treatment improve a Mercedes-Benz?

Strategically installed Focal BAM treatment may provide a worthwhile improvement.

A Mercedes-Benz may experience:

  • Door-panel resonance
  • Trim vibration
  • Road and tyre noise
  • Cargo-area resonance
  • Speaker energy escaping through body panels
  • Reduced mid-bass performance
  • Rattles at particular frequencies

BAM treatment may help:

  • Strengthen the speaker mounting environment
  • Reduce selected panel resonance
  • Reduce sound escaping behind the speaker
  • Improve mid-bass control
  • Reduce selected rattles
  • 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 panels
  • Tailgate
  • Selected trim interfaces
  • Custom subwoofer enclosures

Treatment must not interfere with:

  • Door drainage
  • Window mechanisms
  • Door locks
  • Wiring
  • Side airbags
  • Pressure sensors
  • Seat-belt mechanisms
  • Ambient lighting
  • Vehicle-control modules
  • Factory amplifier cooling
  • Battery ventilation
  • High-voltage equipment
