So a mono amp with 500w @ 2ohm?
Also, I think I'm going to buy a box, and then in the future build one.
As far as wiring the subs together, is it like wiring anything else in a series? One wire from one sub positive to one sub negative and then the other terminals to their same sign on the amp?
So:
AMP[+][+]SUB[-][+]SUB[-][-]AMP
