1. check your wiring - RCAs, speaker wires etc. polarity correct?
2. Did you wire your dual subs in series or parallel? 2 ohm or 4 for the speaker?
3. adjust your input sensitivity.

I think the sub amp u have is an AB class stable to 2 ohms (not 100% on the specs). If they are the 2 ohm verion you may be wiring too much load per channel. Since its DVC its most likely the way its wired. If it IS only stable to 2 ohm keep each sub at that.
