Sorry what I mean is I have a wire harness adapter ( after market) and I wanted to by pass the rear amp
the harness is a 2 pice unit one is neg, pos switched ,pos constant , remote power, and front speakers, the other is rear speakers and rear amp .
So what I was asking is will there be any problems if I just connect the negative (black), the two (red and yellow) positives and front speakers wires (gray gray/black white white/ black ) th
and wire the rear spekers directly to the after market stereo ?
Thanks again Sal
