If you got an aftermarket headunit, your best bet would be to buy a wire harness for your year car to hook up into the factory harness in the car. That way, you don't have to know Acura's color codes for speakers and stuff like that, all you gotta do connect the wires from your headunit to the wires of the wire harness you will need for your specific car. Then when you go to put the headunit in, all you have to do is snap the clips together which the wires go into. Make sense?? If not, email me, I can explain more in depth and a place to get the wire harness.
