Many good suggestions here! I'm also surprised at the L/R front level difference (It's a HUGE difference). Check to make sure the connections are secure.

As far as the sub goes, according to Audyssey your sub is working because it is trying to attenuate the signal by 12db. I would try to fix the L/R channel problem first then re-run Audyssey again.

Also, keep in mind that you sub will be drawing about 15% more current because of running it at 100V versus 120V. Keep an eye on the power light ever now and then because you stand a better chance of blowing the sub fuse at higher listening levels.

Good Luck!
