Stereo System Help...from you rockers out there!!!

[ChevyDude]

Well we all know if there is a will there is a way, and I have been trying to figure out my stereo system and need some advise from some of you whom have done "your" system. I have not put a nice system in a car or truck for some years now and want a fairly nice rockin unit. It doesn't have to be the best, but I would like it to be nice. I am going to use a Pioneer DEH-P85DHR (I already have it and by itself it is 45wx4) to build around. It has all the Sub adding plugs and two amp pre outs so it seems as though it will be fine. I just bought a Infinity Kappa Perfect 6.1 / 6.5" Component set that comes with their nice 6.5" pair and 1" tweets and also a pair of Kappa 6x9's for behind the cab in the corners. I will build some fiberglass kick panels for 6.5's and also for the 6x9's. Here is the question: Which amp should I add??? Legacy, Infinity, MTX, Pyle, Fosgate any other and what wattage??? Next should I get some Infinity Perfect 10's??? What subs and how many...one or two. What size 10", 12" ??? I'm thinking the sub or subs will fit between my bucket seats where the gas tank was. Any help from the Rockin' audiophiles is totally appreciated!!! Do I want a 2 ohm or a 4 ohm sub?
