You are pushing both cabinets with one 4002?  That would seem to be vastly underpowering the subs.  Better would be two 4002's, each running in bridge-mono.  No limiter required.

The XTI 4000/4002 have only little amp headroom, from such an amp you need at least twice up to as much as four times the continuos power rating of the speakers, especially on subs. So only one amp would work but also sound pretty bad.

The continuos power rating for each sub is 700rms 1400 program 2800 peak so being that the continuos is 700 that would be like 3 times the amount of power or are you refering to the program power of 1400 that i would need 3 times that amount which would put me way over my peak of the sub.

Are these your speakers?

Then it's 600W continuous per box, you have two boxes, if you connect them in parallel to get  4 ohms, you have 1200W continuous, 2400W program and 4800W peak, the XTI 4000/4002 is slightly weak for this. Like Kevin said you're better off using two 4002 that way you work with one cab at 8 ohm per one bridged mono 4002 on each amp.
