That box is built to order with 8's or 10's, not just 12's. I'm actually looking for a box exactly like that but use for storage and not subwoofers. I've used Jensen, Alpine, Kenwood, and Lightning Audio amps. Had no problems with any of those. I'm sure someone else would have a better recommendation.

if you haven't already done so, check my car domain in my sig.
one problem with that box you have chosen up there; you will have to cut out the rear speaker panels to get the box to fit.

dude, stop. don't go to crutchfield.
way too expensive. that sub is only $99.99 at sonicelectronix.com
you paid double...
return it, get these subs (same thing, but single voice coil/ 2 ohm each, so combined total of 4ohm)

TS-SW1001S2

and run this amp (500RMS at 4ohm):
KAC-9104D

That will run 250 RMS to each sub, and they are rated to 300RMS, so they will last quite a long time, and will sound incredible. I'm only running one at 300RMS now and it's loud.

Also, custom build a box. I'm building a box and getting rid of the speaker mounts in the back, and all the other extra crap that takes up room. everything behind the seats I'm pulling and just going to make a flush, carpeted box that will house two subs, two speakers, and two amps.

Go with the setup I posted here, its great, and give's quite a kick and a good balance between rock and rap directed subwoofers.

2 12s behind my seat so you could go even bigger if you want... its possible
