This vehicle was upgraded with aftermarket speakers and subwoofer previously, so the only remaining task was to replace the factory amp and tune it all up which is exactly what we did on this brand new BMW 3 Series G20.

New Setup:

The new car stereo system installed by Soundtech included:

A new BMW sound system in all models from 2020 up, whether it is the basic version or the S676 Hifi, is no longer upgradeable with the conventional Plug ‘n Play solution MATCH UP 7BMW. That is because the new models are made the way which is commonly called as the RAM setup, (Radio-Amplifier Module). It means the OEM Amplifier is no longer removable as the head unit will not function without it.

Fortunately, we have a great solution available for these sound systems and the best part is, it still all remains Plug and Play! We will keep the OEM amplifier in place and add a 7 channel MATCH amplifier to the system and connect it all with a special harness. This way we will be able to amplify and tune-up all 7 channels in your BMW vehicle. That is both the front and rear channels, the 2 under-seat subwoofers and the centre channel.


This setup is suitable for all BMW models from 2020 up with both the Basic and the S0676 HiFi sound systems. Please contact us to check the compatibility with your vehicle.


Dynamic sound, clear tones and a great bass frequency response.

The stage has been precisely tuned up with the sound image oriented for the driver’s seat. That way it’s a much more enjoyable experience to drive the car around.

Installation time: 1 day. Please feel free to subscribe to our Youtube channel (Soundtech) for more content.

The Soundtech team has been factory trained and licensed by Audiotec Fischer to install these systems, so you can rest assured that you have the very best working on your vehicle every step of the way.
