depends on the configuration of your subs (2ohms, 4ohms.., SVC, DVC..?)
and to which configuration will your amp provide 1200 watts (2ohm, 1ohm..?)
regardless though, don't pay attention to the peak power.

» 100 watts RMS x 2 at 4 ohms (200 watts x 2 at 2 ohms)
» 400 watts RMS x 1 bridged output at 4 ohms (4-ohm stable in bridged mode)

you can bridge your amp at 4ohms and provide each sub with 200 watts.

you have to bridge one of the left channels and one of the right channels to the sub.
