OK I am trying to troubleshoot this problem let me know if you find the flaws. Or if I am right and my headunits outputs are crapped out. Ok I put the power cable from the pos batt term to the amp. Power wire check. I put a ground wire from a bolt on the body to the amp. Ground wire check. I put a remote wire from the headunits harness and ran it to the amp. Remote wire check. OK I ran my rcas from the back of the unit to the amp L and r. Rcas check. Ok wire my speakers pos to pos on amp neg to neg. Speaker wires check. Turn on vehicle. CD player plays amp gets power subs dont do shit. Pissed off CHECK. WTF I take another sub I have plug it in pos to pos neg to neg. Still NOTHING. Change out RCAs to a new set. Nothing still. Anyone point me to the light at the end of the tunnel?
