what is the colors for the 2004 pontiac grand prix speaker wires? my friend wants to hook a sub up to the stock cd player but none of the wires are labeled.

go to walmart and get a factory harness adapter then you will have every wire you need
labeled, and if you can't read, its also color coded

ummm i dont think walmart carries the newer harnesses( i may be wrong, mine doesnt!). you can go to best buy or circuit city and get one(or local stereo shop). however i would just reccomend hooking up your Hi-low adapter to the rear speakers, look in the trunk at the rear deck you should see them.if you have a "Monsoon" system you may have 4 speakers back there, if so there will be two sets of speaker wires for highs and lows, tap into the lows for running subs. sometimes there may be just 2 6x9's back there but they can also have two sets of speaker wires.
