I'm not sure how this applies to the gear that you have, but my system initially started out more for home theater and over the years the focus has shifted to two channel listening. I have 4 subs plus a HSU MBM-12 (12" "mid-bass module").
The four subs are connected to one pair of outs on my preamp, which has a home theater bypass option. Each pair of subs are connected to one output using a Y splitter.
The MBM-12 is connected to my Marantz pre-processor, which is only engaged for home theater. The four subs are located throughout my living room in the fashion of a "distributed bass array" as best I can given space limitations.
I have the subs optimized for music, but they also work great when I watch movies and the MBM-12 adds some visceral grunt to explosions, gunshots, etc. It's easy to switch back and forth between music and home theater and both sound great.
