Let's hear'em...just got asked the other night to take 160 hz out completely.

That must be one helluva bump at 160! JOOC, what was the rationale behind that?

It also would make sense to know the actual balance between backline rig level and bass in FOH level, and the distance from bass cab to subwoofer cluster[s]. Otherwise it doesn't mean beans.

Tell us a little more about how that plays into the scheme of things. We had a really weird set-up last evening where all 3 amps (including the bass amp) sat 3-4' behind us and we had the subs clustered stage right next to the main (on tripod).

All room modes aside (dimensions of room and how they affect specific low frequencies), when you have the same low frequency-oriented signal being reproduced by several sources (enclosures), they can work complimentarily (coupling) or destructively (cancellations). This is dependent on being either closer than 1/4 wavelength or not (or at least 2 wavelengths apart).
This is one reason that in venues not especially large the subwoofers should be in one tight cluster rather than separated, and why a bass rig on stage will often interact with the subs to make some frequencies louder and others almost non-existant. It's why I tend to either let the bass rig carry the room if that is more practical, or roll off its low end considerably so that it is not fighting with the subwoofers.
