I don't see it either anymore. The person who said you needed Y-adapters provided a link to a subwoofer manual showing how to connect subwoofers to a preamp with only one pair of outputs It used Y-adapters to send the signal simultaneously to the power amplifier for the main speakers and also to the subwoofers. I can't find it now. I think the guy erased his post.
However, it's really straight forward. The two inputs on the subwoofer are designed to blend two stereo channels into one mono signal for using a single subwoofer. If you have two subwoofers you only need to connect to one input on each subwoofer -- either the right or left -- it doesn't make any difference. The only possible reason I can see for using a Y-adapter would be if you couldn't get the sub to play loud enough when connecting to just one input. Therefore, connecting to both inputs using a Y-adapter should give you 6-db more gain.
Good luck,
