The PO of my 1990 760Ti had replaced the OE stereo deck with a single kenwood cd player. However, they bypassed the OE amp and therefore only use the door speakers and the rear speakers. I want to splice the dash speakers into the door speakers but I can't seem to find the dash speaker wires. I am certain however they are not 4 blackwires in the original hareness unless they have power through them (ask me how I know the black wires have power through them). Would they be powered, ie spark when touched to something metal? Does anyone know what colors the wires are for the speakers? Right now there are eight speaker wires attached to the cd player yellow/white, gray/yellow, gray, white, brown/yellow black/yellow, green/brown, green/gray. As you can see from the picture of the harness the new cd player wasn't exactlty expertly installed.
