Hello everyone. Ok i have the harness hooked on the factory harness. I had an alpine or any other radio for that matter and it used to only play but no sound till you get around the factory amp. One harness is hooked on all speakers. Second one is red-power, yellow-memory, blue-remote wire, black-fround, orange-illumination. Now on how i had before one of them was hooked on a pair making three wires hooked together to bypass the amp, I don't remember since i already took the alpine and putting a kenwood. Alpine going to diff. car. daily beater hehe. Anyway, if you know what wires are which i highly appreciate it. I always hooked this thing and its been so long since i have done it and it is like grrrr. I am about to hotwire the damn thing if i don't find solution. Thanks guys in advance.
