First of all peak power doesn't mean anything and is useless, so don't ever pay attention to it. As far as wiring the sub with DVC you still only use one hookup from the amp not two. Follow the guide at
this link, where you hook the amp positive to one sub positive, and place a jumper between the two sub positives, and place the amp negative to sub negative, and a jumper between the two sub negatives. This configuration will show a 2 ohm load to the amp, so supposedly you'll get 600 watts, but its a sony amp so you won't really get that much most likely. For anyone interested
this is a list of wiring diagrams for almost all possible amp and sub wiring configurations. Good luck and tune it when its in so it sounds good and don't drive the amp to clipping because that will damage the sub if its not a heavy duty sub.
