According to
http://www.treoonline.com/csx.html those subs are 2-ohm DVC. A 2-ohm DVC can be wired in parallel for a 1-ohm load, in series for a 4-ohm load, or each voice coil can be amped seperately, for 2 2-ohm loads.
The specs for your amp:
Bridged:
650w @ 4 ohm
900w @ 3 ohm
1200w @ 2 ohm
Stereo:
170w x 2 @ 4 ohm
260w x 2 @ 3 ohm
360w x 2 @ 2 ohm
400w x 2 @ 1.5 ohm
To get the most power, you should wire each voice coil to a seperate channel on the amp. Then, make sure you feed each channel with the same signal (split a mono signal with a y-cable). Make sure the gains and filters are set exactly the same on each channel on the amp. This should give you 720w to your sub.
To get the full 1200w to the sub, you would need a 4-ohm DVC sub, or a 2-ohm SVC.
