As stated a DD 2500 or 3500 would do well also. You have quite a few options just need to decide. And another amp would be a Viper 1200.1, if you can find one, I had two, they are still functional now and they pushed the hell out of my 4 15" Orion P Series. Hooked one up to my brother's 2 12" Kicker CVR, the new models, and with the gains on less than 1/3 it was about to make the subs jump out of the box. I had never seen those CVR's move like that or be that loud. And this was only at a 2 ohm load. It put out a clean 50v at 2 ohms, too much for the kickers.
