I am looking at the Polk Audio db212-2 and the Polk Audio db212-2. Almost all of my home theatre speakers are polk so I am leaning towards the polk subwoofer. What amp (1000 Watts) would you recommened for this subwoofer. I dont know how to match the specs to the subwoofer to specs on the amp but I know its important to pick the right amp for the right subwoofer.
