I run this on my Pyle PTA1000 on the 250 watt bridge channel. I filter out the high channel with a Rolls tiny two way crossover. I seriously couldn't believe how bad some of the reviews on this subwoofer were when I finally fired this up. Holy crap was I impressed. It blew my Logitech X-530 5.1 Speaker System's subwoofer away (but considering that it's an upgrade from a 70watt roughly 6" sub to an 400 watt 15", I'm not too surprised it's much louder and harder hitting).
