I need advice on bi amping

Are you two done now or do I have to send you to your rooms? ; )
All insight- even though contradictory at times- is an opportunity to learn, so I thank you all. 

I bought the additional amp and will try things out. My thinking is I bi wire each side with a horizontal configuration as the amps are not actually going to be exactly the same even though they are the same model. And here I go into the vortex.

A challenge I see is that the old Citation is set up for two "system" outputs, so one to each amp, but I also need my subs connected. One is a Phase Tech 10, the other an Infinity, both powered. 

Thanks for your collective input. Perhaps I am being sucked into the vortex. I have yet to turn it up past half volume, so maybe I am just being a "look at my massive system" guy, though I am literally the only person who ever sees it (the neighbors hear it sometimes). The specs recommend 250 watts and I am pushing them with 100 a side. 

I am running a pair of re-built Veritas 2.4s. Would bi-wiring them add an appreciable difference? 

So I received my 2nd Quatre DLH 100 and wired it into the system to run the high pass with my other one run out to a subwoofer and then back to the low pass on my Veritas 2.4s. Everything is sounding great and looks good, too.
