Im loving this sub! Right now I have it in a ported box wired down to 2ohms on my old fosgate amp and at 300watts. It's bumpin' in the back of my lincoln. Definitely going to get a bigger amp and another one of these! I always recomnd Rockford Fosgate to people who aren't sure what to get because they sound good and bump hard. By-the-way, this sub is pretty big so you might have to do some work to get it to fit in boxes you get from Sonic.
