This is what I would get...

Head Unit: Alpine CDA-9813 http://www.ikesound.com/product-product_id/1301

Rear Speakers: Infinity Reference 6002si (run off head unit)http://www.ikesound.com/product-product_id/1338

Front Components: Infinity Kappa Perfect http://www.ikesound.com/product-product_id/470

Amp For Components: US Acoustics USX2100 http://www.thezeb.com/caraudio/us_acoustics.html

I would go with one sub (THIS WILL GET VERY LOUD!!!)...
Sub: Adire Audio Brahma 12" http://www.adireaudio.com/mobile_aud...hma_series.htm
(In a sealed 1.5 CF box, make sure at least 3/4 inch thick walls, this is large sub)

If you wanted the 2 12's (The Brahma would still be louder)...
Subs: Adire Audio Shivas http://www.adireaudio.com/mobile_aud...vers/shiva.htm
(Also in a sealed box with each sub getting about 1.5 CF)

Amp for Brahma (Wired at 1 Ohm getting 1250 watts RMS) / Shiva Pair (Wired to take a combined 4 Ohm load getting 700 watts RMS total for pair) : US Acoustics USX1000D http://www.thezeb.com/caraudio/us_acoustics.html

You may also want to include a Cap:
