I've got my sub hooked up via a Y-cable as well.

Also, thanks for the second link. A link to a bunch of links about anything HT is always handy to have saved off. Heck, I clicked a random link, and it was THX 7.1 speaker placement. I only have space in my HT for 5.1, but I was surpised that they put the "6th and 7th" speakers side by side in the rear. I've seen most people put them in rear separated from each other.... Interesting...
