Yes, it's an Infinity IL20a.
What may be an issue will be whether your kit all has
a common earth, and how well designed it is.
Which leads me to a follow-up question... If I'm powering this system
off of a non-grounded outlet, can I fashion an effective ground by
connecting the 3rd wire to a water pipe, or heating pipe? (if yes,
which would be better?).
Thanks again,

Adding an odd ground would really cause serious problems. Appliances
dumping current into the outlet ground could pump a few amps through
your equipment on its way to the water pipe.
If you do have a ground loop problem, run a separate wire between the
chassis of the sub and the stereo. That will take some of the current
off the audio coax. If it still hums, add an isolation transformer to
the audio line.

Yeah, all the components, including the sub, will be plugged into a 10
outlet Power Wedge. Based on what everyone's saying, I should be fine,
I guess.
Thanks,
