I have a 2006 Q7 S-Line and drivers side ( right side since I’m in the Uk) doesn’t work and subwoofer. Idk if it’s the Bose Amp or the actual speakers themself. Or what could it be? I keep reading about replacing the amp, or connecting a fibre optic loop to bypass it? I don’t know what to do, if anyone else had this problem please get back to me.

 

it can from the Bose Amp or the actual speakers themself.

 

hi all I even replaced the tuner and still no sound. Speakers are all good.

car was reset at an Audi certified repair shop in Florida. The amp is new too.
