Ok this is the final update. I wound up giving up on my car audio install skills and the audio express fools and bringing the car back to CAW. The guys there did a great job. The system now offers crystal clear sound, and great response for highs mids lows. Finally.
It turns out that audio express had used three scotch locks on the ground wire at the head unit and they ran the third rca next to the amp positive... Never again will i go to them for anything.
