I think I am gonna go with one of them anyway. I have heard they are pretty good. And I don't have the money to spend on some great competition subwoofer. I think people underrate boss amps. A buddy of mine had one running two 10" JL subs and they sounded good. If I could I wound go with an audiobahn amp but everything is just too pricy. But I really like their subs, a buddy of mine has 2 12" audiobahn subs, not sure which model, but he only paid about $100 for each of them, and they pound hard. However, he does have an audiobahn amp pushing them, but there isn't too much power going to them. But I think their subs are good quality.
