Decided to save some $$ and probably go with a single 15" setup.

Amazon.com: Alpine Type-R SWR-1542D - Car subwoofer driver - 750 Watt - 15": Car Electronics

Will this amp power it well?
Amazon.com: Hifonics Brutus BRZ1200.1D D-Class Mono Block 1 x 450 @ 4 OHMS, 1 x 900 @ 2 OHMS, 1 x 1200 @ 1 OHM: Car Electronics

I'd be doing a 4ohm DVC sub wiring it to a 2ohm load. On this amp a 2ohm load is 900rms, the sub rms is like 800. Right?
