Ok, so i went out and bought some brand new components for my car, with extra thick wiring and everything all seamed peachy, until it got to actually connecting said wiring to the back of the head unit. There is a black plug which plugs into the back of the head unit that all the wiring goes into and all i need to do is remove the existing wires and place in the new ones. If anyone knows how i can do this please help me!
