I want to build a bass machine (basically). I want something that pounds hard.

I guess around 2,000 rms - 4,000 rms? I would like to hook it up to two subs in the rear seat/trunk area.

Money.... I'm looking to buy online to save money, unless Speed N sound has cheap enough prices for the item. Budget is around 1000$. I read in a thread a guy had a 2-channel Pyle Chopper series amp rated at 2x 1,500; but I couldn't find out what Ohms go to it!!!!!! I think i'll get one of those Kenwood Excelon head units for a ipod hook up. dunno what else i'll really need. Any help thanks
