Mercedes Benz E43 Audio Upgrade

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.

1. Measure the factory system — we analyse your OEM setup with calibrated microphones and REW (Room EQ Wizard).

2. Configure the new system — we set gains, crossovers and polarity so everything performs correctly.

3. Precision DSP tuning — we bring the REW data into our DSP software, time-align each speaker and apply EQ for a balanced sound.

4. 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.
