DIY Stereo Install suggestions

[VIPER D.N.A]

So Ive decided I want to do a nice box (05 RC) with an amp rack and probably two twelves. I intend to wrap in matching black leather and possibly some fiberglass and paint work. Now, I've never done this before and I don't know all that much when it comes to stereos, electronics, etc. But, I've got a nice woodshop as well as a paintbooth and I've played with fiberglass a little. What I'm thinking about doing is buying some pre made sub enclosures for the sound quality and then building a larger box around them to incorporate an amp rack and give it the look of being "molded to the interior. I've got a nice clarion flip out monitor for the head unit (impulse buy) and the rest is stock. Probably plan on leaving the door and dash stock for now and focus on the enclosure.
Does anybody have suggestions on pre made enclosures? Is this the right route to go? Also what enclosure, subs, amps, etc.? I havent followed up on the newer equipment lately.
My concerns: 1. I hate rattles! If I go the route of pre made enclosures and build around them am I inviting problems when the bass hits?
2. I don't want to give up any comfort or manuverability of the seats.
I have no idea what I'm doing when it comes to installs so ANY help would be much appreciated. Am I starting off in the right direction?
