components are so much better than coaxials. if i were you, i would NOT spend any money at circuit city or best buy - unless you are getting an employee discount.
try this amp for your door speakers-

maybe this for a pair of SVC\DVC4 10" speakers - trucks dont have that much depth, so 10's might be all you can fit.
if you use SVC4 subs, you will get ~200x2, if you use DVC4 and wire each to 2 ohms, you will get ~300x2.

heres a well priced set of comps, ive not used them - but they are a good price for what they appear to be;

heres a wiring kit that will be able to pull enough current to power both amps - with wire left over-

heres a fuse block that will split your 4awg wire to each amplifier

buy like 10 feet of this to go from the distrobution block to each amplifier, and then use the extra to hook to your ground(s) on each amp to somthing like a seat bolt.

here is another RCA to hook the second amp up (the first kit only comes with one)

and you are definatly going to want a few terminals;
8awg rings (used to hook the ground from the amplifier)

and some speaker wire to hook your subs to your amp;

and if you can fit, a pair of these would be sweet, but if you got somthing like this, id recommend a bigger amp for the subwoofers;
