My rear speakers and sub woofer have never worked in my Avant and if I fade to the rear I get no sound. As I think these are all powered by the amp, what's the best way to test if the amp is working? ie, test power to the amp, then test output from the amp (as well as input).
Also, it's not a Bose system
Cheers
