watsup i have an 02 with the onstar and factory amp, i just picked up the pioneer premier 6x9 and 6.5 component tsd series speaker set but im havin trouble figuring out what the + and wats the - ...any ideas'? and should i use the crossovers that cam with it or leve the factory ?
thanx

 

This should be right:
Constant 12V+ Orange
Switched 12V+ Yellow
Ground Black/White
Illumination Gray/Black
Dimmer Brown/White
Antenna Glass
Front Speakers 5 1/4" Doors
Left Front (+) Tan
Left Front (-) Gray
Right Front (+) Light Green
Right Front (-) Dark Green
Rear Speakers 6" x 9" Rear Deck
Left Rear (+) Brown
Left Rear (-) Yellow
Right Rear (+) Dark Blue
Right Rear (-) Light Blue

As far as the new crossover goes, you'll be okay to leave the factory one...Just connect the factory wires to the new speakers and you'll be good to go.

 

I didn't even waste my time trying to figure that out, just hold the wires to the speaker terminals, you can tell if you have it right by the way it sounds. You won't hurt anything doing this either so don't fret.
