I just bought a 2005 King Ranch F150....Im putting in the Eclipse 5500 DVD/Navi unit to control my audio needs and the dvd player that my truck already has hanging from the ceiling....my questions are: how do i make my Eclipse unit control the factory overhead flip down dvd player? what size subwoofers should i get to go in the truck (im thinking two 10 inch subwoofers) and where is the best place to put them? what about mounting the amplifier? should i build a custom box or does anyone know of a box already made for my model truck? im also going to put exhaust on it and was wondering if anybody had heard how 4"tips sound?

Thanks for all your help,
