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

wiring colours:

Radio 12v	RED / white	+	radio harness
Radio Ground	BLACK/ white	-	radio harness
Radio Ignition	(GMLAN Serial Data)
Radio Illumination	(GMLAN Serial Data)
Factory Amp Turn-on	same as power antenna wire
Power Antenna	pink	+	radio harness
LF Speaker +/-	tan - gray	+,-	radio harn or amp in pass side trunk
RF Speaker +/-	lt. green - dk. green	+,-	radio harn or amp in pass side trunk
LR Speaker +/-	brown - yellow	+,-	radio harn or amp in pass side trunk
RR Speaker +/-	dk. blue - lt. blue	+,-	radio harn or amp in pass
