Setup of Fathoms

[Bluemeanies]

I need some assistance as I am not sure after reading some posts on the JLAudio forum as to how to setup my subs for the best solid heart kicking bass.

I have the Fathom 110 and 112 connected to my Outlaw 990 processor pre-amp out. I also have the Oppo 93.
I do not use these subs for music...strictly movies.
Since I have both of these subs connected to my pre-amp outputs should I also be connecting in the multi-channel configuration (7.1) from the Oppo to the sub output of my processor 7.1 configuration?
Also how should I have the menu setting in the Oppo for the sub.

Thanks,Frank
