My rear speakers don't work. I've tried a new subwoofer and still the same problem. I was told it could be the amp so I got one of those. The big question is where is it located? Someone said under the drivers seat but I can't find it there. Any help would be great.

 

if its a disco 1 the amp is mounted on the back of the speakers in the rear door.

 

actually my D1 has the factory amp under the driver seat.
