Im puttin a system in a 00 pontiac sunfire tomorrow and i have a converter for the RCA cabels since the cdplayer doesn't have the outputs on it, it has 4 wires, 2 + and - for right and left side. Now can i just spliss these into the red and black wires on the factory speakers, or should i go behind the cd player and find the right wires. ?????

go behind the cd player,any local shop should be able to tell ya the right color codes on the wires.
