BMW Top Hifi DSP

My BMW Top Hifi DSP amp in my 2006 330i is toast after some water damage. What are my options? Are my only options to go get a new or used amplifier? Any aftermarket options that will run me less than an OEM amp replacement?




Thanks in advance for the assistance.

FYI

There are sometimes used ones for sale on Ebay or here.

this guy says he repairs them

You could recode the head unit to Hi Fi get a Technic harness and amps or ms-8 and
amps and upgrade the speakers . Unfortunately because of the fiber optic connection between the amp and head unit there isn't anything compatible with the L7 amp but the BMW Head Unit.This would be cheaper than going to the dealer and sound better but not as cheap as a used
amp or a repaired one.

You have 3 options.

1. Get a used logic 7 amp.

2. Recode to hifi and use any amp that accepts balanced inputs.

3 Replace the headunit and you can use any aftermarket amp.
