This video is a great one for those of you who want to learn more about how we choose systems and may help you understand more about your BMW audio upgrade.
Frequently asked questions
-
This varies depending on the system, the level of fabrication required and the size of the job. For clarity, we list estimated timescales on each of our packages. We believe in doing the job once and doing it properly — not rushing it. A consultation will give you a realistic timeframe for your specific vehicle.
-
Yes. We design all systems in a fully reversible way using quality connectors and 3D-printed adapters. That means when it’s time to change cars, we can remove the system cleanly and re-install it in your new vehicle.
-
Yes. Most of our clients start with a consultation. You can see and hear our demo cars, get a tour of our facility, and we’ll build a system that suits your goals, your vehicle and your budget.
-
We have clients from all over the UK — including London, Birmingham, Manchester and even Scotland. Many travel several hours because they want their installation done once, and done right. We also offer hire cars and can help with transport if required.
-
Yes, we have many clients from Europe, the Middle East and the USA who ship their vehicles to us for audio upgrades. If you’re based internationally, we can help arrange transport and coordinate your installation from start to finish.
-
Sound deadening transforms how a car sounds. By reducing road noise, panel vibration and resonance, it allows the system to deliver clearer sound and better bass. It also makes everyday driving more enjoyable — even when the system’s not turned up.
-
A passive system uses crossovers to split the audio signal after it leaves the amplifier. A fully active system gives each speaker its own amplifier channel, allowing far more control over tuning and sound quality. Active systems deliver more clarity, precision and adjustability — perfect for high-end installations.
-
A DSP (Digital Signal Processor) allows us to precisely time-align, EQ and tune your system for your specific car and seating position. It helps remove peaks, dips and reflections caused by the vehicle’s shape. The result is clean, balanced and incredibly detailed sound.
-
We follow a clear, structured process so the system sounds amazing in your exact car and for your taste in music.
Measure the factory system — we analyse your OEM setup with calibrated microphones and REW (Room EQ Wizard).
Configure the new system — we set gains, crossovers and polarity so everything performs correctly.
Precision DSP tuning — we bring the REW data into our DSP software, time-align each speaker and apply EQ for a balanced sound.
Tune to your music — using your favourite tracks, we fine-tune by ear for tone, staging and detail.
-
No. We use modern, efficient equipment designed with EVs in mind. The systems we install have minimal power draw, so your driving range isn’t affected.
-
We offer a lifetime warranty on all our workmanship. If anything fails due to how it was installed, we’ll put it right.
All parts are covered by the manufacturer’s warranty, typically between 2 and 5 years. We’ll also help handle any valid claims with the supplier to make the process smooth. -
Yes. We have multiple demo cars on site so you can experience different levels of audio systems in person. It’s the best way to understand the difference a proper system makes.
-
Transparency is standard here. We document your installation with step-by-step photos and short videos, so you can see exactly what was done and how it was done. We can include serial numbers for key components, wiring and fabrication progress, and snapshots of DSP/REW settings used during tuning. You’ll receive this media as a record of the work — it’s one of the big reasons clients choose us.
-
We’re a large, experienced team working from an 11,000 sq ft purpose-built facility. Every bay has custom racking so parts removed from your vehicle are stored safely. There’s plenty of space around each car, reducing risk and allowing our engineers to work cleanly and efficiently. Support engineers can assist your lead engineer whenever needed, keeping quality high and timelines realistic.

Customise the look👌
Want it matte black, metallic red or a rainbow colour? Any colour, any finish - we do it all!
The BMW has used a very unique sound setup in their cars for many years. Most people are disappointed to say the least with the sound quality of the standard audio system on BMW’s, comments such as “no bass”, “no detail”,” muddled” and “distorted” are not uncommon.
We have several different solutions available and can offer bespoke systems which we are happy to discuss in person, our most popular upgrades are detailed above.
How to tell what system you have from factory:
► BMW Base Sound System: No tweeter location, no grill on top of the door
► BMW Hi-Fi Sound System: A tweeter location with a grill on top of the door
► BMW Harmon-Kardon Sound System: A tweeter location with a grill on top of the door with the the HK Brand written on the grill
Transform Your BMW Audio: Unleash the Ultimate Sound Experience!
If your BMW has HK, its no problem for us to upgrade at all, in fact, ultimately, although a little more involved, a HK equipped vehicle will produce even better sound quality than a non HK vehicle. If you are looking to upgrade your HK system, we recommend you start with level 4 upward.
BMW design their cars to be the “Ultimate Driving Machine”. Unfortunately, BMW stopped short in the audio department. The audio quality is lousy, the music seems weak, almost lifeless and if you ever try and crank it up, things only go downhill from there!
But wait, there’s good news. We can make your BMW sound amazing! Our team has developed audio upgrade packages that have proven so popular that we do them for BMW clients across the UK.
The BMW audio system has received criticism from some for its speaker quality, which can sometimes sound muffled or distorted, particularly at higher volumes. The audio system is also susceptible to road noise, which can detract from the listening experience. The low-end frequencies often lack the resonance and impact that is expected in a premium audio system, resulting in a flat and uninspiring sound.
BMW G Series is the latest model range, this covers a wide variety of vehicles. If you are looking to upgrade your BMW G Series, feel free to book a consultation so we can advise on the best solution for you. The packages are here to give you an idea of budget plus timescales for work. We also offer bespoke solutions for BMW car audio upgrades.
