Hello, recently I bought an Audi A3 2000 1.8T, and it seems like it has a bose sound system. At least it has Bose subwoofer, which is not playing. Front and rear speakers are working fine, rear speakers are little weak compared to front, but still they work. I read that if subwoofer is not playing, then rear speakers could not too, but still they work. All is connected, Subwoofer is connected, Bose amplifier is connected too, all seams like it is stock, not touched since car left the factory. Also I have stock CD changer with Audi Concert 1. All is working except that subwoofer. Where can I look for solution? Also, if that will make any difference, my radio unit is codded in standard mode. When I codded it to Bose mode, it didn;t make any difference, except for worse sound quality, so I left it at standard coding.
