My friend is running his off of a memphis MCD1000. Sounds great and hits hard.
But that doesnt do much power at 2 ohms. Ive got an IA 20.1 id sell you. Itll do 950rms at 2ohm(underrated too). But your better off going another direction. Unless you wired it at .5 ohm. Then youd have 25-3000rms on tap!!!.
