Don't listen to the don't knows about the power to the subs. My LVL 5;s only get about 1k each and get down just fine. I would bet at my power I'm just as loud as some of the guys with double my power. I'm getting tired of all this talk about not having enough power to move a sub. It's fuckin ridiculous.
Austin,
shoot me an email and I will forward you the 2 designs I have for the 250. You can build either the 4th order or the ported.
Hell if you were closer, I would make ya a hell of a deal on either box
