I'm trying to figure out why my front door speakers aren't working. The tweeters in the front are working just fine though. I pulled out one of the speakers from the door and tested it out and they work. I played around with the amps in the back and it seems that one of them isn't supplying power.. My question is which amp supplies power to the front speakers and which one supplies power to the rear ones? Could it be something other than my amp?

 

I think it's the driver's side amp... anybody?

 

start simple, check all the fuses. I don't mean check the ones you think would be blown, I mean check them all... Often circuits are linked to other circuits that you would not think to check....

 

ended up that the drivers side amp went bad. Time to get a new one.
