BMW S0676 HiFi Sound System Upgrade

Model: BMW 328i F30 2014

The medium-range series of the BMW sound systems on all models up to 2020, the S0676 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:

The BMW’s original stereo system included:

    • S0676 HiFi sound system factory amplifier,
    • 3-way splits in the front:
      • 1″ tweeter
      • 4″ midrange
      • 8″ under-seat woofer
    • 2-way coaxial system in the rear:
      • 4″ speaker
    • Mediocre sound quality
    • Not enough bass
    • Low volume output

For the new speakers and underseat subwoofers, we used the brand 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.

New Setup:

The new car stereo system installed by Soundtech included:

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.

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.

Compatibility:

This setup is suitable for all BMW models with the S0676 HiFi system all up to the year 2020. Please contact us to check the compatibility with your vehicle.
