Was not certain where to post this and this seems to be the most popular Amp forum.

In my post Katrina set up I do not currently have a dedicated subwoofer. Just a 5.none system. My uni room apt is about 8-9000 cubic feet (much bigger than most dens). Rather than buying a sub or subs and spending lots of money, could I use or modify existing equipment with good results?

I have an unused pair of Klipsch LaScala speakers and I can have 2 - 4 available (unused) channels from my Outlaw 750 Amp (165W/ch, X 5 channels).

Qs:
1. I think 165 W is not powerful enough to run any of the new commercially available subs on the market. LaScala's are very efficient speakers though, but is 165 W enough to run it as a sub? New subs are powered by 350-500-1000 W amps. Can I safely bridge or combine 2 channels off the 750 Amp to create a 330W Amp? If it is safe to do this exactly how do I connect the channels and output to the LaScala sub?

2. Can a Klipsch LaScala be used as a sub if I directly wire into the woofer and bypass the crossover network? Would the old Klipsch 12" driver be ok, or would I need to replace it with a "modern" dedicated 12-15 or 18" subwoofer driver? Would such new drivers require at least 330 W? Mind you, opening up a LaScala might require major surgery. But to save megabucks, I would do it.

Any and all thoughts appreciated.

My rig:
26" 20 yr old Sony TV - even Katrina couldn't kill it!
Outlaw 990 pre/pro
Amps:
a. Outlaw 750 (165 W/ch x 5 channels) - but only 3 channels currently used, powers Klipsch Academy center channel speaker (c. 1992) and Klipsch Heresy's - surrounds c. 1980,
b. McIntosh MC-240, powers my Klipschorns c. 1980,
c. and an old stereo amp (2 channels work most days), which could be used for the Heresy's. (Thus I have 4 potential unused channels off the 750).
Klipsch LaScala speakers, currently not used, c. 1980.
