2001 A4 avant - Where is Bose stereo amp? I have been fighting this problem for a year now, but I have to get it solved. Last winter, the sound started to get all distorted when cold, and would get better after it warmed up. It has been getting steadily worse and worse and now is always bad. I replaced the HU but it still did the same thing, so I figure it must be the amplifier. Can anyone tell me where the hell the amplifier is and how to get to it? My hope is to get the amplifier out and try to find a replacement one from ebay once I know for sure what it looks like. The dealer has been zero help and I am starting to go crazy. |
