sorry i wasnt really clear, i havent installed anything yet, as for the wires i need input on what size to use. The front door will have Boston acoustic components (RC520) 5 1/4. The rear door will have BA (NX87) 5x7, and the rear deck has BA (NX97) 6x9. The two subs are solobarics. The amp for the front speakers is a 2ch and rear doors and rear deck will share a 4ch.

does that help a little more?
