thats exactly what i need to know. and also, i didnt see any rca's when i took out mystock HU, are the speakers attached through the wiring harness?

Your factory radio wouldnt have any rca hook up all sound comes through the indiviual speaker wires (puple,purple with black stripexc.) there should be four sets of speaker wires on solid and one same color with black strip. If your going to use an external amp for your door speakers you wouldnt need them hooked up
