According to this link, that amp will work OK with the front 2 channels running in 2 or4ohm stereo for your comps, and 4ohm mono for the sub. The built-in Xover means only 1 set of RCA's and around 200wrms for the sub.

If you try and run the sub off the amp bridged down to 2 channels, the 2ohm per channel load will cause more problems than it's worth.
