"I also wanted to buy 1 KLIPSCH AW-800-SW to give me more bass"
You can't run one passive sub off both channels.
Seriously, I think this "2 stuff" stuff is waaaaaay overrated.
Look, you need another amplifier for the second zone. Then you need a pair of speakers, too. At this point you've pretty much got a complete system less a source component.
When all is said and done, all "zone 1" is is a line level source.
I'd just as soon use a receiver instead of the integrated amp, slap on a low/moderately priced CD/DVD and have what was "zone 2" morph a full blown standalone system.
Of course, one could still run a line level feed from the mother ship's "zone 2" output into one of the receiver's line level inputs if you want the same thing in both rooms at the same time. Nice for parties but, on the whole, not worth theeffort on a day to day basis.
...sorry... just my daily rant. ...I think I need another caipirinha. You anywhere near Fort Smith?
