Amplifier no coding data stored / ASD no valid coding for equalization

Hey guys,

I have a sound system issue with my BMW. When radio is on, music will play for a few seconds and cut off then play again for few seconds and cut off (this cycle repeats). If I turn the volume off a crackle and pop noise comes from every speaker one at a time. Active sound does not work either.

I scanned my car and I have the following codes:

- B7F481 (AMPH: No current coding data stored)
- B7F484 (AMPH: Control module is not encoded for the vehicle)
- B7F4A8 (Bass speaker, front left: Malfunction)
- 8053A5 (ASD: Invalid coding data for equalizing)

From my research the amplifier needs to be coded to the car. Are there any DIYs out there that can show me how to fix this on my own.

Any suggestions will help.

Thank you,
Andriy
