You could still use the splitter though and just run the 1 cable from the 1050 to the splitter and then plug the 2 ends of the splitter into the 2 inputs on your sub. Thats what I used to do a very long time ago with my old Polk sub.
I have read in other places of a "gain" by using a splitter but I'm not sure if they mean using one when you have 2 pre-outputs on your receiver or the 2 inputs on the sub, but it couldn't hurt. I think my REL said something like that?
