1999 Chevy Malibu Stereo Wiring

So I just got my Malibu at an auction last night, and the guy who put it in there I guess had subwoofers and a nice stereo.  SO, he took all the speakers out and the radio out.  Today I just bought the speakers and hooked them up, and bought a cd/fm stereo.  NOW, I just can't hook the stereo up cause I do not know the wiring system for this.  There is a black and a white connector with about 15 different colored wires.  Anyone know which color is what????  And also, I can't get the front speakers in the doors to work, are there supossed to be speakers there or is it the wiring?????i just got a 1999 Chevy Malibu, and I dont know anything about it :( If someone would be able to help me, I would greatly appreciate it. lol.. Email me please

And Check the wiring to the front speakers. Sounds like there is a problem there.Alpine CDA-9833 HU
