No sound out of left side

[75MillerJet]

Just what the title says... I get great sound everywhere but the left speakers. What are the possible causes? I messed with the RCA's and got nuthn. My setup is one 2 channel amp supplying a 12" sub and another 2 channel supplying my left and right 6.5's. Both amps are powering up just no sound out of the left side. ???

I'd swap the rca's around, and determine if the problem was at the amp or head unit.

Just swap left to right and right to left in regards to the rca's at the amp. If you still have no left audio then do the same to the speaker wire as the rca's before. If now the audio works on the left but not on the right then the amp could be bad.
Now if the audio switches when you swap the rca cables then it could be the rca's or possibly the head unit.
