i have 2 12 inch mtx thunder 8000. 400 watts cont. Would the Kicker KX800.2 that push enough power for these?

 

what is the impedence of the subs? 4ohm? 2ohm? If they are 4ohm, your only going to get 200W per sub. If 2ohm, then 400 per sub. Seeing that they take 400w, I would try for an amp that will supply 350-400w to each one at the proper impedence.
