if there 4ohm dvc you can only wire to final load of 1or 4 ohm. keep that in mind when buying an amp. i would try and keep the rms around the rms of the sub. i heard the newer type R's dont stand up to there ratings very well. you could get a re audio dts1000.1, audiopipe apsm 1500. just a few amps in the range your looking for. if you need any install help ill be willing to lend a hand.
Then I meant DVC 2ohm. I would need a 2 channel amp, it probably wont be this years model type r's, havent bought em yet but I don't like the blackface type-r's.
