connect sub woofer from preamp out on integrated?

yes, I am running the Gallo speakers full range....plse explain what bass management means.....thx.....

Indeed, that is very helpful. My Epos sub has hi and low level inputs/outputs (with a variable frequency cut off filter) and I think I am starting to understand what needs to be done....unfortunately, the Classe CAP 101 has pre amp out, but no Amp IN jacks....could I use the Tape IN jack instead of an Amp IN? Thank you for your patient guidance.

Thx again for providing thid info. I probably need to re-think this system. Fortunately it is a second one.
