I've searched the net for hours on end, and I can't seem to find a wiring harness diagram for an '07 G5 GT 6 disc changer with the included 10" subwoofer and 6 speakers. I'm trying to wire in an RCA converter to install an additional amplifier and 2 12" subwoofers, but I've encountered many problems. I've isolated the left and right rear speakers, ignition wire, ground wire, and power wire, but I'm having trouble figuring the polarity of the speaker wires without a tester. Any help would be greatly appreciated.

Usually in the G5's and cobalts they'll be a wire harness in a black cover running from the woofer to the amp on the back which will be the Sub leads (white(+) black (-)) if you have a problem with that just goto the rear speakers and all GM's the + polarity is the darker colour (IN THE REAR ONLY) good luck
