I am wiring up a pair of 5.25 infinity kappa coaxial speakers. I am going to disconnect the dash speakers. Do I just need to clip the wires to the dash speakers and wire in the 5.25's in the door, or is there some other way to wire this setup? The 5.25's will be powered off an amp. Also...

My 87 GN was broken into. The CD head deck and sub with amp were stolen. The passenger door lock was messed with to gain access. There is about a 1 cm hole just beneath the lock. The truck was also opened in a similar manner, and won't close completely. The center pod where the stereo was...
