I have two 12" Pioneer Premiere 3000 Watt subs (RMS wattage: 2000). (link: Pioneer USA - Champion Series Pro)

I am wondering what amp would you reccommend to take full advantage of these subs. My budget is anywhere from $250-$500 (I am hoping to make an online purchase to save a lot of money).

Oh yah, and I don't want anything crap either. I was looking on ebay and found a few really cheap amps that have a loooot of power (or so they say) but they're not really well known name brands in the car audio industry.

Thanks
