I have a 1999 Mustang gt. that the local "fancy car audio place" told me ,without looking at it or checking anything, that both amps in the back are shot. hmmm seems odd to me that they would both go at the same time. But what do i know. ok so my question is three part. (1) does anyone know where i can find replacement amps?( 2)how would I go about checking to see if in fact both amps are shot?(3)where can I find the amp bypass harness I would need to replace the radio.? Thanks
