Help

I decided not to do anything to the outside of my truck besides a paint job. I am gonna try and get a system put in it. I want atleast 2 Infinity 12's behind the seat. The truck is an "extended cab" so there is plenty of room for it. I need to get a head unit. I need help with picking a good head unit, what size amp to put in it, and what size are the door speakers? If I could just get someone to please help me out. All I know about the speakers is they max out at 1200 watts each. Thanks.

if i were you i would go with a 600 watt amp bridged and that should put enough to both of them to get them thumpin as for the door speakers i think they are 4 1/2 in
