Ok so i was putting in a new system for my car and accidently connected the pos. and neg. wires for my speaker lead while the radio was on ( yes very dumb i forgot to shut the power off to it) and it caused the speaker output to fail. Though when i turn the radio on with the speaker harness unplugged and then plug it in i get sound. when i change radio stations since there is somewhat of constant sound it stays on but when i put a cd in it stops till i unplug the harness and plug it back in and does the same thing when i skip a track on the cd. Any ideas of what might be going on if this can be self fixed or will i have to continue with sending it in for repairs.
