bridging a theta dreadnaught II

I would like to use 2 channels of the 5 on my Dreadnaught II to run an Aerial Acoustic CC5 center channel. The local Theta dealer is unsure how to do it. Does anybody know if it requires removing the chassis(and sending it off to Theta) or is it a simple procedure. Thanks,ken
I would have used the two channels to biamp. This is what I do (I have an Aerial CC5 and a Theta Intrepid setup like this.) Works very fine!. Anyway I am thinking of going for a Dreadnaught II or a Theta Enterprise later on.
