2002 Cavalier stereo wiring diagram

I'm looking for information about the 4 wires to each speaker in the back, and about the other connecters back there are for.  Hopefully info on the wires will help to figure out what those 2 are for.

Thanks for any help,

Michael

can't quite figure out what you mean?... but I do know that YOU SHOULDN'T CUT THE MAIN HARNESS UPFRONT TO THE FACTORY RADIO... The harness from metra is about 79.95 but it will save you about $1,000 if you cut the harness... In 2001 GM did this thing called data bus (Not sure exactly what it is yet or why they did it, I've heard that the wires talk back and forth to the main computer) But we had a girl come in that her b/f tried to hook up her pioneer after cutting the plug... It blew the factory radio... and amp... and the pioneer they tried to install and something else that cost about $500 I WISH KIDS WERN'T SO IGNORANT TO INFORMATION!!! ASK BEFORE!!!!!sorry for my rant...
