JBL 300.1 (300W RMS @ 2-ohms)...Wire ur sub in parallel, perfect.
Or try an MTX 421D (300W RMS @ 2-ohms).
Basically get a Class D monoblock amp that is is around the rms wattage u need for ur sub...it will be 2-ohm stable if it's a mono amp.

It's interesting seeing suggestions like those above recommending driving a DVC sub in stereo.  I always take Rob's opinion as gospel, and Haem's is harder to get through, but I do my best to understand his ideas, too.  :)  But, I have to say, with subwoofer frequencies, I can't understand spending the extra money, and drawing the extra power from the car electrical system to run a DVC sub in stereo.  With the availabilty of class D amps now, and the low prices you can get them for.  You will draw about 40% less power running a mono amp, and spend half as much, as you will for a stereo amp rated at 150 to 200 watts per channel.  With frequencies at about 120 Hz and lower, you should not hear a difference.  I have a little USacoustics mono amp, the USB600D, that would run that sub nicely.  I got it for $120 from Crutchfield's, although they are out of them.  But you should still be able to get one for less than $180.
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
