I was driving today and suddenly the sound went out from all speakers except for the one in the center of the dash. Anyone have an idea what could have caused this? Maybe a blown fuse? Weird that 1 speaker still works, though.

 

My guess would be the factory amp in the back.

 

either the factory amp in the back, or your harness got pinched somehow???

 

Ok thanks. I'll check those things out.
