ok so i have a 99 A6 and the rear speakers on the back two doors do not work, are there anymore speakers besides the two on each door? the only ones that i know are working now are the base and tweeters in my two front doors. what could be the problem?

 

Your rear amp (right side of trunk behind the small door) is out. This powers your rear door speakrs and the subwoofer in the same inclosure as the amp. a new rear enclosure will cost about 600.00 if it is a non Bose. Best bet is to replace amp with a aftermarket.

 

where can i get one and how the hell do i do this?
