Hey, i got a pair of 8 ohm 12 W0 s in my camry. You dont need that much power bud. Im running a power acoustik gothic series 2 channel thats 520 peak and i cant run full load on the subs, but trust me, the mothers hit.
You need an amp that will bridge down to a 2 ohm load, most class D's do, but I like the class A/B amps, many will argue that they are the same, but they are not. Finding a class A/B down to 2 ohm will cost you a little more than a class D though, so if your trying to save money then just get a class D. Otherwise the 250/1 will work perfect you can get a good price on those too.
You might wanna look at these amps http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=13761
they are about as good as they come. Power Acoustiks are good too for the money. Don't buy a Rockford, or you'll pay for the name. I've seen a lot of bad Sonys too. Anything other than that is good. I have a q logic box that is two seperate boxes in one or it looks just like a regular box, but has a divider in the middle. I'd go with one box and mount the amp on the back. I made mine theftproof too. Too bad you don't live around here, I want to sell my 12's in a box for $125, and you could have got a real nice amp. Check www.thezeb.com for poweracoustik amps; they have about the best price and free s/h. I'd recommend getting a warranty, as amps become a disposable item when broken. Good Luck.
