I know people are pissed about everyone recommending audiopipe, but its cheap for the money. The AP15001D does 950rms @ 2 ohms and is a mono block for 160 shipped on ebay.
If you want to spend a little more, get something else but i dont see any problems with those audiopipe amps, i run one myself to my 9515D and so far has been real good for the price.
Might possibly be able to get a hold of a kicker 1000.1 if your interested? Im pretty sure it does 1000 @ 2 ohm, but i would have to check on the model number and make sure first.
