BMW 676 HiFi Sound System Upgrade

The medium-range series of the BMW sound systems on all models up to 2020, the 676 HiFi, is also the one that is the easiest to upgrade. For this purpose, we use a solution that has been developed and produced in Germany by Audiotec Fischer, the world’s leading car-audio manufacturer.

Original Setup:

676 Hifi sound system factory amplifier,
3-way splits in the front: 1″ tweeter, 4″ midrange, 8″ underseat woofer,
2-way splits in the rear: 1″ tweeter, 4″ midrange

Mediocre sound quality, not enough bass, low volume output

New Setup:

MATCH UP 7BMWΒ – PnP DSP amplifier
STEG BM45CΒ – Direct fit speakers in the front
STEG BM8Β – Drop-in underseat subwoofers
STP Aero – Premium soundproofing system

We have replaced the factory amplifier for MATCH UP 7BMW that fits in directly, the matching harness comes with the amplifier. It was followed with the same style replacement of the speakers and the underseat subwoofers. All the parts we used have been made to fit BMW so there was no need for any modifications other than undoing a few bolts and putting them all back. All 4 car doors have been soundproofed and after the whole setup was active and ready, we tuned the sound in and the job was done.

For the new speakers and underseat subwoofers, we used the STEG. STEG is a high-quality Italian brand that has great components with a very flat frequency response to begging with. They sound very natural and pleasant to the ear, perfect for everyday use.

Compatibility:

This setup is suitable for all BMW models with the 676 HiFi system all up to the year 2020. Please contact us to check the compatibility with your vehicle.

Results:

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.
