Re: Pioneer KEH 3250qr wiring diagram
Well generally black is earth, red is power on from ignition, yellow is always positive memory wire, blue or blue/white strip is remote antenea, and the rest well they should be speaker wires, 4 sets, Front Left (+,-), Front Right (+,-) and so on, or the may share a common negative.
Test the speaker out wires with an old speaker, and just adjust fade and balance to one corner i.e. Fornt Left then mark them , then move sound to Front Right etc.
Well hope that helps :0)
