Room construction is a huge factor in wall reflectance in the subsonic range. I will guess you moved from stick-built walls, above grade to cinderblock walls below grade? The latter do not absorb or transmit sound, so it's nearly all reflected.
And that's a very bad thing... you now have huge room modes to deal with, either by using multiple subs at a range of locations (for uniformity; they won't increase sound levels) or adding low frequency absorbers to reduce the reflected energy. Or both.

Noob does not mean unreasonable, and you're not asking an unreasonable question. Here's a good link regarding subs:http://en.wikipedia.org/wiki/Subwoofer
Your issue is frequency range, section 2.2 of that page. Subs are designed to produce frequencies below ~100 Hz. Your amp will produce frequencies from 20-20KHz. You need a way to a) cross over to the sub so it only sees freq. below 100Hz or so, and b) cross your other speakers so they don't see frequencies below 100Hz or so.
Normally, that's handled by the AVR. Your Denon has a line level subwoofer out, I'm sure, so the crossover circuitry is there, but intended for use with a separate amp. It is theoretically possible to use the other two channels as you desire, but...
What's not so common is an external input to the zone 2/surround channels. If you can plug in an iPod, for example, and listen to it on the zone 2 speakers while using the other channels to watch a movie, you have the required connectivity for what you want to do.
If there are no separate inputs that can allow you to port LFE out to one of the zone 2 amps, the sub would need a speaker-level low-pass filter to cut the sub above 100Hz, and a pair of speaker level high-pass filters to cut the speakers below 100Hz. For the kind of money that requires (big coils are expensive), you could buy a plate amp and be done.
Especially since Parts Express' plate amps are on sale; $50 for 70W is a very good fit to an Anarchy TH. Plug 'n' play with your Denon's LFE output.http://www.parts-express.com/wizards...AT&srchCat=505
