Thread: Rear Channels Stopped Working

I have a 2000 GTP with Bose system, Last week while shutting off my car i heard a pop. Next morning, i noticed i lost all but 1 rear channel, and have no bass what so ever. Is this the amp? or speakers? I know it past cars a blown speaker just sounds like crap, but still get audio. Dont want to buy a used amp if its not the amp that is the issue.
Front channels still work.

Not sure how electrically inclined you are, but you could try jumping wires from the speaker that works to the other possibly blown speakers to see if they have output.
