I'm planning on getting the Alpine SWR-12D4 subwoofer in a ported box. The amp needs to be close to 1000watts at 2ohms (I don't think 100watts less will make that much of a difference). My budget is $280.
Is the Hifonics Brutus BRZ1200.1D any good? On SonicElectronix it's frequency response is listed as 35-250Hz, but I have some songs that have lower frequencies than that. And it also has something about a subsonic filter. So I'm confused on what frequency this amp cuts off at.
