I plan on using the ICBM with stereo subs and am curious as to how it works.

Here is what I want to do:
On the preamp, turn off the sub (.1) channel and set the 5 channels to large.
Send the 5channel to the ICBM and XO at 100hx. Use the L/R sub out for the stereo subs.

Does this sound ok?

How does the ICBM matrix the 5 channel full range signals to form stereo subs.

the L/Rsub outs ...they are they stereo and not mono ...right?
Thanks.
