I am pretty sure this is what is wrong with the sound system.
Any other ideas?
What about the head unit? Check the tone controls? Maybe something reset, or blew out. I had a front left and rear right speaker problem in my car when I bought it. Tried a new trunk amp, but it was actually the radio that was bad. Can you swap for a known good radio to test?
