Audio buyer guide
Start with what your car already has. A standard system, a Bose system and a Burmester system need different parts, interfaces and installation methods. This guide shows how to identify yours, which upgrades make sense, and what a fair, reversible installation looks like.

Short answer
The best upgrade is the one that fixes your actual complaint on your actual system. On a working Bose or Burmester car, better settings or a well integrated subwoofer may be enough. On a standard system, matched speakers and a signal processor can make a clear difference. Check the PCM version, the factory sound package and any earlier work first, then choose parts that fit both physically and electrically, and keep the original parts so the car can go back to standard.
Know your system
Porsche offers different factory sound systems across model lines and years. The figures below are from Porsche published pages for the model shown there. Speaker counts and power differ between models, so treat them as examples, not as your car.
Base
The factory system fitted when no premium option was chosen. Speaker count, amplification and processing vary by model.
The usual route is matched speakers, a processor and a compact subwoofer.
Option
Porsche lists 14 loudspeakers including a subwoofer, 14 amplifier channels and 710 watts for the system shown on its UK sound page, with Centerpoint 2, AudioPilot noise compensation and SoundTrue enhancement.
The usual route is a settings review, subwoofer integration and targeted speaker changes.
Top option
Porsche lists 21 individually controlled loudspeakers and more than 1,455 watts, a 25 cm active subwoofer with a 400 watt class D amplifier, and air motion transformer tweeters.
The usual route is to keep it, tune it and repair faults. Large changes rarely add value.
An independent review of the 2026 Macan Electric measured the Burmester option at 21 speakers, 21 channels and 1,470 watts, and preferred it clearly over the Bose system in that car. Bose also states on its own Porsche page that system details and market availability change, so one badge does not mean one specification.
Terms explained
Identify your car
Grille badges and a registration year are not enough. An imported car, a replaced head unit or earlier aftermarket work can all change what is fitted. These records give a reliable picture.
Signal path
Every audio system is a chain. Knowing where the new part joins the chain tells you what can change and what can break.
Source
CarPlay, Android Auto, Bluetooth, USB or radio. Quality starts here.
Head unit
Handles sources, volume, phone calls, navigation prompts and many warning tones.
Link
Some cars carry audio digitally between units, for example over a MOST fibre link. The interface must suit that exact link.
Processing
The factory amplifier sets levels, crossovers and effects. An aftermarket processor usually joins here.
Output
Drivers must match the load, size, depth and mounting of the car.
Fault or preference
Weak bass, one silent door, crackling on one source and unclear phone calls are four different complaints. Some need a repair or a settings change, not an upgrade.
Upgrade paths
Step one
Diameter is only the start. Mounting depth, basket shape, adapter rings, connectors, grille clearance and window travel all matter. The electrical load must suit the amplifier and its crossover.
Ask whether the original mounting points and trim stay untouched.
Step two
A DSP adjusts channel levels, equalisation, timing and crossovers where the hardware allows. It needs a clean, suitable input. It cannot repair a damaged speaker or undo a distorted signal.
Ask which input the processor takes and which factory functions pass through it.
Step three
An active subwoofer has its own amplifier, a passive one needs a separate amplifier. Either way it needs correct signal routing, a secure enclosure and an agreed loss of luggage space.
Ask how level, crossover and phase will be set with the existing speakers.
Often enough
Sound damping in doors and careful settings can reduce buzz and improve clarity at low cost. On premium systems this is often the first sensible step.
Ask for a before and after listening session at the same volume.
Bose and Burmester systems are designed and tuned together with the cabin. A different taste in sound is not proof that the factory amplifier is weak or that every speaker needs replacing. In many cars the right result after a proper listening session is to keep the system and adjust it. Upgrades make most sense on base systems, damaged systems, or when you want something specific, such as deeper bass, that the current setup cannot give.
Reversible installation
Plug and play describes how parts connect. It does not promise that removal is free, damage free or complete. A supported adapter harness can avoid cutting the factory loom, but it must suit the car, the amplifier and the signal link. Audiotec Fischer harness information shows how specific these adapters are.
Agree this in writing
On hybrid and electric models, audio work never involves high voltage cables or traction parts. Equipment must stay clear of cooling paths, airbags and service access.
Retained functions
A good music demo is not a complete handover. These functions should be checked and signed off before you collect the car.
Every agreed source, volume, balance, fader and any sound modes you use.
Microphone, incoming and outgoing calls, voice control and the return to music.
Prompts must stay clear and duck the music as before.
Parking sensors, seat belt and other chimes routed through the audio system.
Volume, track and phone buttons, plus the factory screen and menus.
Start, shutdown and sleep, with a parked drain check if new amplifiers were added.
CarPlay and Android Auto change how your phone connects. They do not improve speakers or acoustics on their own. For phone integration see our Porsche Apple CarPlay page and Android Auto page.
Proof of result
Installer evidence
For any finished project an installer shows you, ask for the car configuration, the named parts, dated photos, the wiring method, the settings and the measured or listened result under stated conditions. A speaker photo or a generic graph does not prove success on your configuration.
By model
The same upgrade does not suit every Porsche. Cabin size, roof type, speaker space and where a subwoofer can go all change the plan.
Small cabin with rear seats close to the engine. Door speaker space and depth are tight, and a subwoofer competes with the front luggage area or rear seats.
Roof up and roof down sound very different. Tune for how you actually drive, and protect electronics from rain and washing water near the roof seals.
Two luggage areas and a mid engine. Space for amplifiers and subwoofers is limited, so compact parts and clean routing matter.
Larger cabins with more room under the luggage floor. Factory subwoofers on premium systems often sit there, which shapes any bass upgrade.
Four seats to cover, so balance between front and rear matters. Agree which seats the tuning should favour.
Audio work stays on the low voltage system only. Mounting must avoid cooling paths and high voltage components entirely.
Avoid these
A kit sold for one Porsche generation may not fit another, even with the same speaker size.
A louder demo feels better for a few minutes. Matched volume comparisons show the real change.
Removing a well tuned Burmester system to fit generic parts can cost a lot and sound worse.
New speakers often expose loose trim. Fix the buzz first or the upgrade will disappoint.
Once wiring is cut, going back to standard costs more and may never be perfect.
Calls, chimes and steering controls should be checked before you drive away, not discovered later.
Price and warranty
Assessment figure from our diagnostics page and CarPlay figure from our CarPlay page, both including VAT. Audio parts and fitting are quoted for your exact car.
Parts. The component maker covers its product, on its own terms.
Workmanship. The installer covers the fitting, on stated terms.
The car. Ask your Porsche or Porsche Approved warranty provider in writing how the proposed work affects your cover. Terms written for another country may not apply to a UAE car.
Also agree who pays for fault tracing, removal and retuning if a new part fails, and tell your insurer if your policy asks for modifications to be declared.
A parked car in summer gets very hot inside. Choose equipment rated for the temperatures it will see, mount amplifiers where air can move, keep cables protected from sharp edges and heat, and keep water away from door electronics. There is no reason to retune a processor every season. If the sound changes, find out why first.
Questions
Sometimes. It depends on the speaker load, the channel processing and the physical fit. Ask for application data for your exact system, not just a matching size.
Not usually. Identify the complaint and check the settings first. Many Burmester owners are best served by tuning or a repair.
One independent review of the Macan Electric preferred Burmester clearly. Results still depend on the model, the source and your taste, so listen in a similar car if you can.
No. CarPlay changes how the phone connects. Sound quality still depends on the source, settings and audio hardware.
No guarantee. It describes the connection method. Check calls, prompts, chimes, controls and power behaviour after fitting.
Only if nothing was cut, drilled or bonded and the original parts are kept. Agree the removal labour and the checks in advance.
Ask your warranty provider in writing before work. Parts warranty, workmanship warranty and the car warranty are separate.
It can be, if space, mounting and integration are planned. Agree how much luggage space you will lose before choosing an enclosure.
Only on the low voltage audio system, with the correct procedures. High voltage parts are never touched for an audio job.
