Which amp would work better for 2 subs?

-Which of tris amps would be better to power 2 Boss NX129DC Onyx 12" Subwoofer Dual 4ohm Voice coils running them at 1 ohm and How would i wire it. And why do mono amps have 2 positive and 2 negative outputs for subs.

1. HFi1000 Hfi Series D-Class Mono Amplifier 1 x 475 @ 4 OHMS, 1 x 750 @ 2 OHMS, 1 x 1000 @ 1 OHM

2. Brutus BXI1210D 1200 Watt D-Class Mono Amplifier

3. New Hifonics Brutus Brz1200.1d 1,200 Watt RMS @ 1 Ohm (Cea-2006 Certified) Monoblock Super Class D Amplifier with High Efficiencyyou dont need a class D amp you need a class A/B mono amp since the subs is not a high powered speaker!! take a look at the boss phantom amps class A/B cause like the dragon said you'll blow that sub up! but if you get the Dual 2 ohm sub you could use a class D. im also curious to know about the kind of box you putting it in.honestly any of them would work great. the brz would be the best, but its not going to be a whole lot better than either of the other 2.



and mono amps have more than one set of speaker terminals to make it easier to wire together multiple woofers. they still tie together into one channel
those boss subwoofers do not handle anywhere near rated power. i suggest you get the hfi1000.the larger amplifiers would just be a waste of money. with the larger amps you would also risk blowing the subwoofers.
