What I did was remove the main deck, the main speakers doors, tweeters, subwoofer and the factory amp. This was a BIG pain in the ass but now I have everything perfect. When I removed the stock amp, I found what wires went to what speakers in the car now since I kept the original dash speaker and the original back deck speakers those were the only ones I needed.
