With the 1200d's you can strap them together to the sub at 2ohms so you wouldnt have to match the gains //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
lanzar opti2000D? about 2000 watts rms at 0.5 ohm. should power the sub nicely and are fairly cheap. i got one myself //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
