I installed my sub and amp. The amugh amp is through a Line out converter. After putting it all together and turning it on it just cuts out the rear speakers and just makes a loud noise constantly.

 

Make/model/wiring scheme??? Maybe it's supposed to sound like that if you hooked it up wrong enough

 

1999 toyota corolla. Yeah I know I have something wired up wrong becuase when I had done the same thing in my Integra it worked out fine. I believe I have something backwords. Probably one of the positive and negative wires going from the rear speakers to the Line out converter.
