I am not sure what you are asking (stripped wire?), but I just used the RCA cables that were coming out of the wire harness that they sent me without any modifications. I connected the fronts (assuming this is all four door speakers) to the front RCA jacks and the rears (I assumed this was the speakers behind the seats) to the rear RCA jacks like in the picture. However, I think that people are mentioning that the speakers behind the seats are not really considered to be the rear speakers and they are not considered to be the subs, so I am a bit confused. lol

I realized last night that my speakers behind the seats are not producing any sound, so I definitely need to make a change of some kind.
