What sub to pair with my amp?

Question

I currently have a good start with a alpine amp that puts out 400 rms (i believe the model was 450) but i have it hooked to a 2000 watt audiopipe slim mount 12 in a truck box (so im almost positive it doesnt have the needed airspace) and it sort of sounds blown.. nothing happens when i push the cone, so im not certain. So i guess my question is where do i go from here? do you think the box is my problem or should i just go with a entirely new set up? ive been checking ebay and craigslist for good deals and so far the only thing ive found is a mtx 4500, but cant find the rms on it so im not going to buy it... 

also a few added details, im working on a budget (not willing to pay more then $200)... im using this in the trunk of my car... i only want one speaker to save a little trunk space, doesnt matter if its 10, 12, 15.. but i want the best i can get out of my amp with a one speaker combo..

Well the first thing I would try, is multimeter the subwoofer, and to check to see if it is actually blown, or there is a loose wire or something.. Measure the box, H/W/D, multiply those numbers, and divide buy 1728. That will let you know if the box is the right size.. If the box is close to size, maybe some poly fill to make it seem a little bigger...If the box is really small, and the sub is good, a bigger box might be exactly what you need.. Maybe ported. seeing that your amp has roughly 1/2 the rms power...

If the Cone doesn't move at all, it is blown, as I have been through quite a few blown Subwoofers.
