Hi,my car is an Audi B5. A4 tdi avant, 1999.. facelift model..the problem is as follows:Simptoms:1. Front speakers are a lot louder than rear2. Trunk stock bass speaker works when volume low. When slightly increasing volume the bass dissapears..Its a non bose system, with 2 front speakers with tweeters, 2 rear door speakers, and an amp with bass speaker in the left wall in the trunk behind the panels..So my question is: do I need to replace the amp??? Headunit?? Or speakers. ???? Where lies the problem ??thanks allot!!
