More Brand Information
FIAT (Fabbrica Italiana Automobili Torino) is an iconic Italian car manufacturer founded on 11 July 1899 in Turin, Italy, and it has remained deeply tied to Turin through major industrial hubs like Lingotto and Mirafiori. Across its history FIAT grew from early passenger cars into a full mobility group spanning cars, commercial vehicles and global manufacturing, then entered a modern ownership era through the Fiat–Chrysler integration (2009–2014) and the creation of Fiat Chrysler Automobiles (FCA), before becoming part of Stellantis in 2021.
From an SEO intent standpoint, FIAT is best known for compact city cars and affordable, practical family vehicles, plus light commercial vans and utes/pickups. The brand’s highest-demand nameplates include the Fiat Panda (a dominant city-car staple and best-seller in Italy), the Fiat 500 family (including the 500e electric city car), the Fiat Ducato (one of Europe’s best-known large vans), and the Fiat Strada (a segment-leading pickup in Brazil). FIAT is also associated with “smart value engineering” and powertrain innovation: it pioneered work that fed into common-rail diesel injection, developed MultiAir electro-hydraulic valve control for improved power and efficiency, and produced long-running, mass-market engine families like FIRE.
Globally, FIAT is strongest in markets where compact cars and work vehicles dominate, with Stellantis reporting brand leadership in Brazil, Italy, Turkey and Algeria (with models like Strada, Panda, Egea/Tipo, and strong LCV performance via Ducato/Doblò). Looking ahead, FIAT’s stated direction is clear: a shift to electrified, lower-emissions urban mobility, including a publicly communicated goal to become electric-only by 2030 (gradually from 2025), while also adapting to real-world demand with moves like adding a hybrid 500 alongside the 500e at Mirafiori.
Speaker and Car Audio Upgrade FAQs
Fiat vehicles range from compact city cars and convertibles to commercial vans, people movers and motorhome platforms. Their factory audio systems also vary considerably between models, production years and equipment levels.
Selected Fiat vehicles have confirmed Focal Inside speaker solutions. These include particular versions of the Fiat 124 Spider, Doblò, Scudo, Talento and Ulysse.
However, there is no single Focal Plug & Play speaker kit suitable for every Fiat.
The current Focal Australia compatibility information does not list a confirmed direct-fit solution for some of the Fiat models most commonly found in Australia, including the Fiat 500, 500e and Ducato.
Where a vehicle does not have a confirmed Focal Inside listing, an Authorised Focal Australia Dealer may still be able to create a customised upgrade using products from Focal’s broader car audio range.
Depending on the vehicle and required performance, a Fiat audio upgrade may use:
- Focal Inside vehicle-compatible speakers
- Focal Universal speakers
- Auditor
- Access
- Polyglass
- Slatefiber
- Flax Evo
- K2 Power
- K2 Power M
- Utopia M
- Focal amplifiers
- DSP amplification
- Specialised Subwoofers
- Conventional Focal subwoofers
- Custom speaker mounting adaptors
- Factory connector adaptation
- Acoustic treatment
- Professional system tuning
Compatibility must be confirmed against the exact Fiat model, production date, body style, factory radio, audio-system specification and original speaker arrangement before products are purchased.
1. What are the best speaker upgrades for a Fiat?
The best Fiat speaker upgrade depends on the vehicle, factory audio system and the type of improvement the owner wants.
There is no single Focal speaker package that can be recommended for every Fiat.
A suitable upgrade may include:
- Focal component speakers for the front soundstage
- Focal coaxial speakers for rear or secondary locations
- Vehicle-compatible Focal Inside speakers
- Custom speaker mounting adaptors
- Factory connector adaptation
- Acoustic sealing around the speakers
- Door and panel treatment
- A compact amplifier
- Digital signal processing
- A compact or custom subwoofer
- Professional measurement and tuning
The first step is identifying the limitations of the existing system.
Common complaints include:
- Unclear vocals
- Weak mid-bass
- Harsh treble
- Distortion at higher volume
- Poor stereo imaging
- Limited deep bass
- Door-panel rattles
- Poor clarity over road noise
- Weak sound in a van or motorhome
- A damaged or non-operational factory speaker
For a compatible Doblò, Scudo or Ulysse, Focal’s IS PSA 165 and IC PSA 165 may provide a straightforward starting point, subject to the exact model and installation requirements.
For selected Talento vehicles, the compatibility guide lists IS RNS 165 and IC RNS 165 speakers. The 124 Spider has a separate listing using IS FORD 165 and IC FORD 165.
These product names should not be used to infer compatibility with another Fiat. They reflect the mounting and connector arrangement of the particular vehicle listed in the guide.
Where no confirmed Focal Inside solution exists, an authorised dealer can assess products from Focal’s broader range. Auditor and Universal may suit an accessible factory-speaker replacement, while Access, Slatefiber and Flax Evo offer progressively greater performance.
K2 Power, K2 Power M and Utopia M are better suited to advanced installations with appropriate amplification, speaker positioning, crossover design and DSP tuning.
The best solution is the one properly matched to the vehicle, available space and owner’s expectations.
2. Does Focal offer Plug & Play speakers for Fiat vehicles?
Yes, but only for selected Fiat models and production years.
The current Focal Australia compatibility information lists potential direct-fit speaker solutions for:
- Fiat 124 Spider from 2015–2020
- Fiat Doblò from 2022–2026
- Fiat Nuovo Scudo from 2016–2021
- Fiat Scudo from 2022–2026
- Fiat Scudo III from 2022–2023
- Fiat Scudo III Phase 2 from 2024 onward
- Fiat Talento from 2016–2021
- Fiat Talento VU from 2016–2021
- Fiat Ulysse III from 2022–2023
- Fiat Ulysse III Phase 2 from 2024 onward
The products differ between models.
Listed solutions may include:
- IS FORD 165
- IC FORD 165
- IS PSA 165
- IC PSA 165
- IS RNS 165
- IC RNS 165
- IC REN 130
- IW-PSA-YISO
- IW-REN-YISO
A Focal Inside listing does not mean that every component is automatically compatible with every audio-system option.
The installation may still require:
- Confirmation of the production date
- Verification of the original radio
- Confirmation that no factory amplifier is installed
- A mounting spacer
- Tweeter-position inspection
- Removal of interior trim
- Checking speaker depth
- Factory connector confirmation
- Signal testing
- Correct polarity
- Professional installation
The Doblò listing specifically states that the front speaker requires a 17 mm spacer.
Focal Plug & Play amplifier harnesses are intended for compatible factory head units and non-factory-amplified systems. A vehicle fitted with an aftermarket radio or premium factory amplifier may require a different integration method.
Fiat models not listed with a confirmed solution should be treated as customised applications rather than being described as Plug & Play.
3. Which Fiat models can be upgraded with Focal audio?
A Focal audio upgrade may be possible in a wide variety of Fiat vehicles, but the installation method depends on whether the vehicle has a confirmed compatibility listing.
Models with current Focal Australia speaker listings include:
- Fiat 124 Spider
- Fiat Doblò
- Fiat Nuovo Scudo
- Fiat Scudo
- Fiat Talento
- Fiat Talento VU
- Fiat Ulysse
Other Fiat vehicles that may be suitable for a professionally customised installation include:
- Fiat 500
- Fiat 500C
- Fiat 500e
- Fiat 500X
- Fiat 500L
- Fiat 600
- Fiat Panda
- Fiat Grande Panda
- Fiat Tipo
- Fiat Punto
- Fiat Bravo
- Fiat Freemont
- Fiat Fullback
- Fiat Ducato
- Fiat Ducato motorhomes
- Fiat Strada
- Fiat Fastback
- Earlier and imported Fiat models
The current guide marks some newer international models, including the Grande Panda, Fastback and later Tipo, as under investigation.
The 2012–2019 Fiat 500 and 2023–2026 Fiat 600 do not have a listed Focal Inside speaker solution in the current guide. The Fiat 500e and Ducato are not currently shown in the Fiat compatibility table.
This does not necessarily mean these vehicles cannot be upgraded.
It means that an installer must establish:
- Original speaker size
- Mounting arrangement
- Available depth
- Factory connector
- Speaker impedance
- Factory amplifier configuration
- Frequency filtering
- Original equalisation
- Available installation space
- Suitable amplifier and subwoofer locations
Imported Fiat models require additional care because their trim, wiring and infotainment equipment may differ from Australian-delivered vehicles.
Abarth models should also be checked separately. Although Abarth vehicles may share body structures with Fiat models, they can have different factory audio equipment, trim and speaker arrangements.
Final compatibility should always be confirmed using the specific vehicle rather than the Fiat badge alone.
4. Can the Fiat 500 or Fiat 500e sound system be upgraded?
Yes, but neither model should currently be promoted as having a confirmed Focal Inside Plug & Play speaker kit in Australia.
The current compatibility guide marks the 2012–2019 Fiat 500 as having no listed Focal Inside solution. The 500e does not currently appear in the Fiat compatibility table.
A customised Focal upgrade may nevertheless be possible after the vehicle has been inspected.
A Fiat 500 or 500e upgrade could potentially include:
- Compact Focal component speakers
- Compatible coaxial speakers
- Custom mounting adaptors
- Factory connector adaptation
- Acoustic sealing
- Targeted door treatment
- A compact amplifier
- DSP amplification
- A space-efficient subwoofer
- Professional tuning
The Fiat 500 has a compact cabin, restricted trim space and relatively small storage areas. Equipment selection should therefore prioritise efficient use of space.
A large enclosure may be unnecessary. A compact powered subwoofer, ISUB ACTIVE solution, ISUB TWIN or a professionally designed shallow enclosure may be more appropriate, subject to available space and electrical compatibility.
The 500e requires additional precautions because it is fully electric.
Aftermarket equipment must operate through an appropriately assessed low-voltage supply and must not interfere with:
- High-voltage cables
- The traction battery
- Charging equipment
- Battery cooling
- Electric-drive components
- Safety systems
- Airbags
- Manufacturer service access
- Vehicle sleep and wake behaviour
The installer should also verify that phone audio, navigation instructions, warning sounds, parking information and other functions continue to operate correctly after the upgrade.
Fiat 500 Abarth and Abarth 500e models should be checked against the separate Abarth compatibility information rather than assuming that the standard Fiat 500 recommendation applies.
5. Can the Fiat 124 Spider sound system be upgraded?
Yes. The current compatibility guide lists potential Focal Inside speakers for the 2015–2020 Fiat 124 Spider.
The listed products are:
- IS FORD 165 front component speakers
- IC FORD 165 coaxial speakers
Despite the product names, these speakers are specifically listed against the 124 Spider in the compatibility guide. Compatibility should still be checked against the individual vehicle before purchase.
The 124 Spider presents several installation challenges:
- A compact two-seat cabin
- Limited storage space
- Restricted amplifier locations
- Limited subwoofer space
- Road and tyre noise
- Wind noise with the roof open
- Strong reflections from the windscreen
- Speaker locations relatively close to the occupants
- Possible differences between trim and audio-system options
A suitable upgrade may focus on creating a clear and controlled front soundstage rather than installing a large number of speakers.
The system may include:
- Focal component speakers
- Correct tweeter positioning
- Secure speaker mounting
- Acoustic sealing
- Targeted panel treatment
- Compact amplification
- DSP tuning
- A compact subwoofer where space permits
Convertible listening requires additional output and control because wind and road noise can mask vocal detail, treble and bass.
Simply increasing treble or volume is not the best solution. A properly powered and tuned system can improve clarity without becoming excessively harsh.
Any installation should protect:
- Roof mechanisms
- Seat movement
- Storage compartments
- Airbag zones
- Drainage paths
- Original trim
- Vehicle electronics
A discreet, reversible installation is particularly valuable where the owner wants to preserve the car’s original appearance and resale value.
6. Can the Fiat Doblò sound system be upgraded?
Yes. The current compatibility guide lists Focal Inside speaker products for the 2022–2026 Fiat Doblò.
The listed components include:
- IS PSA 165 front component speakers
- IC PSA 165 rear or coaxial speakers
- IW-PSA-YISO amplifier integration harness
The compatibility guide states that the front speaker installation requires a 17 mm spacer.
That spacer requirement is important. It means the installation should not be described as simply removing the original speaker and installing the Focal product without additional fitment work.
The spacer must:
- Provide sufficient speaker depth
- Maintain window and regulator clearance
- Position the speaker correctly behind the grille
- Create a rigid mounting surface
- Resist moisture
- Allow suitable acoustic sealing
- Avoid contact with the door trim
The Doblò is a commercial vehicle, so the audio system must also be designed around its working purpose.
Common objectives may include:
- Clearer phone-call audio
- Improved navigation instructions
- Better podcast and audiobook reproduction
- Stronger music clarity
- Improved performance over road and cargo noise
- Reduced door-panel vibration
- A compact bass solution that does not obstruct the load area
A camper or recreational conversion requires separate planning because it may contain auxiliary batteries, chargers, solar equipment, cabinets and additional living-area speakers.
The IW-PSA-YISO harness should only be used where the factory radio and audio-system configuration are confirmed as compatible. It is not intended to integrate with an incompatible factory-amplified system.
7. Can the Fiat Scudo or Ulysse sound system be upgraded?
Yes. Several generations of the Scudo and Ulysse have confirmed listings in the current Focal Australia compatibility table.
Potentially compatible models include:
- Fiat Nuovo Scudo from 2016–2021
- Fiat Scudo from 2022–2026
- Fiat Scudo III from 2022–2023
- Fiat Scudo III Phase 2 from 2024 onward
- Fiat Ulysse III from 2022–2023
- Fiat Ulysse III Phase 2 from 2024 onward
The listed speaker products include:
- IS PSA 165
- IC PSA 165
The IW-PSA-YISO harness is listed for selected Scudo and Ulysse applications but not every production year.
This is a good example of why the complete model and build date are required. Vehicles that appear externally similar may use different radios, connectors or electrical architectures.
A Scudo or Ulysse upgrade may include:
- Focal front component speakers
- Focal rear coaxial speakers
- Factory-compatible mounting
- Acoustic sealing
- Door treatment
- A compact amplifier
- Digital signal processing
- A space-efficient subwoofer
- Professional tuning
The Scudo is generally used as a commercial van, while the Ulysse is more likely to be configured as a passenger vehicle or people mover. Their listening environments can therefore be very different.
A commercial Scudo may contain a cargo barrier, shelving or tools that create additional noise and vibration. A Ulysse may require more balanced sound for front and rear occupants.
Any amplifier harness must be confirmed against the original head unit and factory amplifier status. Vehicles with premium or separately amplified audio may require signal testing and a customised integration method.
8. Can the Fiat Talento sound system be upgraded?
Yes. The current compatibility guide lists Focal speaker solutions for the 2016–2021 Fiat Talento and Talento VU.
Potential products include:
- IS RNS 165 front component speakers
- IC RNS 165 coaxial speakers
- IC REN 130 for a selected rear position
- IW-REN-YISO amplifier integration harness
The guide notes that the IC REN 130 is out of stock. Product availability should therefore be confirmed before the system is quoted.
The Talento shares aspects of its vehicle platform and audio arrangement with selected Renault and Nissan commercial vehicles. This explains why the listed Focal products use RNS and REN designations.
These designations do not mean that every Renault- or Nissan-compatible product will automatically fit the Talento. Only the specific products and vehicle years listed should be treated as the starting point.
A Talento audio upgrade may be designed for:
- Trade use
- Courier and delivery work
- Fleet operation
- Passenger transport
- Campervan conversion
- Recreational touring
- Mobile workshop use
Large vans can generate significant:
- Road noise
- Tyre noise
- Wind noise
- Cargo noise
- Panel resonance
- Partition vibration
- Cabinet or shelving vibration
Speaker replacement may therefore be combined with acoustic treatment and improved mounting.
Where the IW-REN-YISO harness is suitable, a compact Focal amplifier may be integrated while retaining the original radio. This must be confirmed against the actual head unit and factory audio configuration.
Campervan conversions require additional planning for house batteries, chargers, solar systems and rear entertainment zones.
9. Can a Fiat Ducato or Ducato motorhome be upgraded with Focal audio?
Yes, a customised Focal audio system may be possible in a Fiat Ducato van, cab chassis or motorhome.
However, the Ducato is not currently listed with a confirmed Focal Inside speaker kit in the Fiat Australia compatibility table.
It should therefore be treated as a professionally assessed custom application.
A Ducato upgrade may include:
- Focal component speakers in the front cabin
- Compatible coaxial speakers
- Custom speaker adaptors
- Factory connector adaptation
- Dashboard or door-speaker upgrades
- Acoustic treatment
- A compact amplifier
- DSP amplification
- A subwoofer
- Additional speakers in a motorhome living area
- Independent front and rear audio zones
- Professional system tuning
Ducato motorhomes require more planning than ordinary vans because the completed vehicle may contain:
- A house-battery system
- Solar charging
- DC-to-DC charging
- A mains charger
- An inverter
- Televisions
- Multimedia equipment
- Cabinets and furniture
- Additional speakers
- A separate rear entertainment system
- Equipment installed by the motorhome converter
The driving cabin and living area are also different listening environments.
Front speakers may work well for music, calls and navigation while driving but provide poor coverage when occupants are seated in the rear. A complete motorhome system may therefore need separately positioned living-area speakers.
The installer must determine whether the audio system should operate:
- Only while the vehicle is running
- From the starter battery
- From the house battery while parked
- As two independent zones
- From both the factory radio and a rear entertainment source
Equipment placement must preserve seat movement, storage, access to electrical systems and the motorhome manufacturer’s service requirements.
10. Can I keep the original Fiat radio and infotainment system?
In many compatible installations, yes.
Focal Inside speakers are generally designed to work with the vehicle’s original radio and speaker locations. A compatible amplifier harness may also allow selected amplification without replacing the factory head unit.
Functions that should be retained may include:
- Steering-wheel audio controls
- Bluetooth telephone audio
- Apple CarPlay
- Android Auto
- Navigation instructions
- Voice commands
- Reversing camera
- Parking-sensor tones
- Warning sounds
- Vehicle settings
- USB connections
- Uconnect functions
- Balance and fade controls
However, these functions must be tested before and after installation.
Some Fiat audio systems route warning sounds, calls or navigation prompts through particular speaker channels. Incorrectly disconnecting, filtering or redirecting one of those channels may reduce or eliminate an important function.
Focal Y-ISO harnesses are intended for compatible non-factory-amplified systems using the original head unit.
They may not be suitable where the vehicle has:
- A factory amplifier
- A premium audio option
- An aftermarket radio
- Fibre-optic audio communication
- Unusual speaker impedance
- Active frequency filtering
- A factory subwoofer
- Previous audio modifications
A vehicle with an aftermarket head unit may require a conventional amplifier wiring kit or a different adaptor.
The installer should verify:
- Source-unit outputs
- Speaker impedance
- Signal voltage
- Frequency response
- Factory equalisation
- Volume-dependent processing
- Warning-sound routing
- Amplifier turn-on behaviour
- Vehicle sleep and wake cycles
Retaining the factory radio is often practical, but it must be integrated on the basis of testing rather than assumption.
11. How do I confirm which Focal speakers will fit my Fiat?
Begin by collecting the complete vehicle information.
This should include:
- Exact Fiat model
- Production month and year
- Model year
- Series or generation
- Body style
- Trim level
- Engine or drivetrain
- Australian-delivered or imported status
- Original country of sale
- Factory head unit
- Audio-system option
- Number and location of speakers
- Presence of a separate amplifier
- Presence of a factory subwoofer
- Previous aftermarket modifications
- Campervan or commercial conversion details
Physical compatibility can be affected by:
- Speaker diameter
- Basket shape
- Mounting-hole pattern
- Installation depth
- Magnet diameter
- Factory connector
- Grille clearance
- Door-glass clearance
- Window-regulator clearance
- Dashboard clearance
- Trim-panel clearance
- Factory speaker enclosure
- Required mounting spacer
- Moisture protection
Electrical and acoustic compatibility can be affected by:
- Factory speaker impedance
- Available amplifier power
- Active frequency filtering
- Factory equalisation
- Signal delay
- Volume-dependent processing
- Warning-sound routing
- Premium factory audio
- Factory subwoofer integration
- Vehicle sleep and wake behaviour
The Focal Australia compatibility table should be used as the starting point.
Where the vehicle is not listed, or where the guide states “no” or “under investigation,” an appropriate trim panel may need to be removed so the original speaker can be measured.
The factory signal may also require testing. A simple voltage reading does not establish whether the channel is full-range, filtered, equalised or delayed.
Final compatibility should be confirmed by an Authorised Focal Australia Dealer before products are ordered.
12. I have a broken Fiat speaker. Where can I get a replacement?
An Authorised Focal Australia Dealer can diagnose the audio fault and determine whether a compatible Focal replacement is available.
Possible signs of a damaged speaker include:
- Crackling
- Distortion
- Buzzing during bass notes
- No sound from one location
- Intermittent operation
- Reduced volume
- Weak or missing treble
- Poor vocal clarity
- An imbalance between the left and right sides
- Door or dashboard rattling
The speaker should be diagnosed before replacement equipment is ordered.
Similar symptoms can be caused by:
- Loose interior trim
- A damaged speaker mount
- Moisture inside a door
- Corroded terminals
- A loose connector
- Damaged wiring
- An amplifier fault
- A factory radio fault
- Incorrect balance or fade settings
- Infotainment software
- A damaged factory subwoofer
- Previous aftermarket work
- Incorrect DSP settings
A factory audio system may divide the frequency range between several speakers. A door woofer may reproduce only bass and lower-midrange frequencies, while a smaller speaker handles treble.
A speaker that sounds quiet during an unsuitable test is not necessarily defective.
Where one conventional front speaker has failed, replacing the left and right speakers as a matched pair is generally preferable. This helps maintain consistent sensitivity, tonal balance and frequency response.
The original mounting structure should also be inspected. A premium replacement speaker will not perform properly when installed into a loose, cracked or poorly sealed mount.
If the vehicle has a factory amplifier fault, replacing the speakers alone will not address the underlying problem.
13. What should I upgrade first in my Fiat audio system?
For a Fiat with a basic factory audio system, the front speakers are usually the most effective starting point.
The front soundstage has the greatest influence on:
- Vocal clarity
- Stereo imaging
- Instrument placement
- Treble detail
- Midrange definition
- Mid-bass response
- Phone-call intelligibility
- Overall sound quality from the driver’s position
A suitable first stage may include:
- Compatible Focal component speakers
- Correct tweeter placement
- Secure speaker adaptors
- Acoustic sealing
- Targeted door treatment
- Polarity confirmation
- Factory-signal testing
If the original radio cannot provide sufficient clean power, a compact amplifier may be recommended at the same time.
If weak bass is the main complaint, a compact subwoofer may deliver a more noticeable improvement than replacing every rear speaker.
In a commercial van, reducing panel resonance and improving the front speaker mounting may provide greater value than immediately installing a large system.
In a motorhome, the owner may need to decide whether the priority is:
- Better sound while driving
- Improved entertainment while parked
- Additional rear speakers
- Independent front and living-area zones
- Television and movie audio
- Deeper bass
- A complete touring entertainment system
The first upgrade should address the cause of the owner’s complaint.
For example:
- Rear speakers will not correct poor front stereo imaging.
- A subwoofer will not repair distorted front speakers.
- Premium speakers cannot reach their potential from an unsuitable signal.
- More amplifier power will not eliminate a loose door-panel rattle.
- DSP cannot restore frequencies that are absent from the captured factory signal.
A staged system allows the owner to begin with the most valuable improvement while keeping future amplification, DSP and subwoofer options open.
14. Do I need an amplifier, DSP or subwoofer in my Fiat?
Not every Fiat speaker upgrade requires an amplifier, digital signal processor or subwoofer.
Efficient Focal speakers may provide a worthwhile improvement from a compatible factory radio. This may be sufficient for an owner seeking:
- Clearer vocals
- Improved treble detail
- Better tonal balance
- Stronger mid-bass
- Cleaner sound at moderate volume
- Improved phone and navigation clarity
A suitable amplifier can provide:
- Greater clean volume
- Better speaker control
- Stronger dynamics
- Improved mid-bass
- Reduced distortion
- Greater headroom
- Better performance over road noise
- Power for an additional subwoofer
A DSP can allow the installer to:
- Manage factory equalisation
- Combine compatible factory signals
- Set crossover frequencies
- Balance individual speakers
- Apply corrective equalisation
- Adjust time alignment
- Improve stereo imaging
- Integrate a subwoofer
- Tune the system for the driver’s position
- Control a multichannel active system
DSP becomes particularly valuable when integrating with a processed factory signal or building an advanced system.
However, DSP cannot recover frequencies that are absent from the selected signal. It also cannot make an electrically incompatible speaker safe for a factory amplifier.
A subwoofer may be recommended where the owner wants deeper and better-controlled bass.
Possible Fiat solutions include:
- ISUB ACTIVE
- ISUB ACTIVE 2.1
- ISUB TWIN
- Compact powered subwoofers
- Under-seat solutions where clearance permits
- Boot-side installations
- Shallow enclosures
- Removable enclosures
- Custom motorhome installations
- Selected Focal Specialised Subwoofers
- Conventional Focal subwoofers
Correct crossover, polarity, phase, level and time-alignment settings are essential. A poorly integrated subwoofer can sound disconnected or produce less bass because of acoustic cancellation.
15. Will a Focal upgrade affect my Fiat’s electrical system or warranty, and how much will it cost?
A correctly designed Focal upgrade should aim to retain the Fiat’s original infotainment system, electrical functions and interior appearance.
Audio equipment must be connected through:
- Correctly sized power cable
- Suitable fuse protection
- Secure grounding
- Appropriate amplifier turn-on control
- Compatible speaker wiring
- Properly insulated connections
- Correct equipment mounting
Hybrid and electric Fiats require additional assessment.
Aftermarket audio equipment in a Fiat 500e or another electrified model must remain within the appropriately assessed low-voltage system and must not interfere with:
- High-voltage cables
- The traction battery
- Charging equipment
- Battery cooling
- Electric-drive components
- Safety disconnects
- Airbags
- Control modules
- Manufacturer service access
The system must also shut down correctly when the vehicle is parked. Poorly integrated equipment may prevent vehicle modules from entering sleep mode or discharge the low-voltage battery.
Genuine Focal products purchased through an Authorised Focal Australia Dealer receive a standard one-year Australian product warranty. Eligible products installed by an Authorised Focal Australia Installer receive an extended three-year warranty.
The vehicle manufacturer, selling dealer, converter or warranty provider determines the conditions applying to the Fiat itself.
An audio modification does not necessarily cancel every aspect of a vehicle warranty. However, damage caused by incompatible equipment, incorrect wiring, excessive electrical loading or poor installation may not be covered.
The cost depends on:
- Exact Fiat model and production year
- Factory audio system
- Number of speakers
- Confirmed Focal Inside or custom installation
- Required mounting adaptors
- Electrical connectors
- Interior disassembly
- Acoustic treatment
- Amplifier installation
- DSP integration
- Subwoofer selection
- Campervan or motorhome conversion
- Custom fabrication
- Final measurement and tuning
A straightforward speaker replacement in a compatible Scudo will generally cost less than a complete Ducato motorhome system with multiple zones, amplification, DSP and a subwoofer.
It would be misleading to provide one standard price without confirming the vehicle and the owner’s requirements.
Upgrade Your Fiat with Focal Sound
Whether you drive a Fiat 124 Spider, 500, 500e, Doblò, Scudo, Talento, Ulysse, Ducato or another Fiat model, there may be a suitable Focal audio upgrade available.
Selected Fiat vehicles have confirmed Focal Inside compatibility.
These include particular versions of the:
- Fiat 124 Spider
- Fiat Doblò
- Fiat Nuovo Scudo
- Fiat Scudo
- Fiat Talento
- Fiat Talento VU
- Fiat Ulysse
The listed solutions use different products and installation requirements. They should not be treated as interchangeable simply because they appear within the Fiat category.
The Fiat 500, 500e and Ducato do not currently have confirmed direct-fit Focal Inside solutions in the Australian compatibility table. These vehicles should be professionally inspected before products are selected.
Where a dedicated Focal Inside solution is unavailable, an authorised dealer may create a customised system using Focal Universal, Auditor, Access, Polyglass, Slatefiber, Flax Evo, K2 Power, K2 Power M or Utopia M products.
The system may also include:
- Custom speaker mounting adaptors
- Factory connector adaptation
- Acoustic treatment
- Additional amplification
- Digital signal processing
- A Focal subwoofer
- Factory-signal integration
- Professional measurement and tuning
Commercial vans and motorhomes require additional planning around cargo space, conversion equipment, auxiliary batteries, rear entertainment and equipment placement.
Electric Fiats require appropriate low-voltage integration and careful separation from the high-voltage propulsion and charging systems.
A correctly designed and professionally installed Focal system can deliver clearer vocals, stronger mid-bass, improved stereo imaging, better-controlled bass and a more enjoyable listening experience while retaining the Fiat’s original interior and essential vehicle functions.
