Mid-Range Stopped working

2002crew · 08-15-2023, 08:41 PM

Hey, So recently i noticed my Mids on my 08 e93 m3 were going in and out randomly and now have completely left. I dont notice any sound coming from both driver and pass door speakers.

My question is what are the possible problems?
Amp? Speaker? Wiring?

Its both sides which is strange IMO but my Lows and Highs work just fine.

Yeah which sound system do you have?
The common problem with cars that have the Hi Fi or Logic 7 system is water
gets on the amp.
Hi Fi = option 676
Logic 7 is 677 or 688
There is a possible 4th system called IA Individual audio which is a superset of the
logic 7 system . option 752
use mdecoder.com to find out which option you have.

The same info you need is in the following link

If you have logic 7 there is sticky about how to adjust it at the top or this forum.
