I've put a Fusion Active sub box in the back of my BA - it has high level inputs so it can be wired straight into the rear speakers. Anyway, everything was going well for most of the afternoon, nekminit all speakers stopped working, fuse is fine, power is going to the sub box, power is going to the ICC, just no sound... Any ideas??? Here is a link t the sub box I got: http://www.fusionentertainment.com/car/products/active-enclosures/en-ab2122
