Pre-Fab Box - Not Making Any Bass?

Basically... At this point it probably seems wasteful, but it'll give me plenty of room to grow. But if I'm understanding what you're saying.... Wired to 4 ohms, is that subwoofer neutral position? Amp in question is a us amps ax2000. Really it's a 2 channel amp that can be bridged. Let's just say per sub, that's still like saying 1000 watts rms x 2 @ 2 ohms (if I find some old school pioneer premier 12's they will complement this amp perfectly). So a 42hz tone would be something like the amp seeing 6 ohms? Do the ohms rise and fall with the frequency or opposite? These questions could apply to the OP as well, but I'd love some insight as well here. OP, would you prefer we make a separate post?
