I have two completly different question.
First, does anyone use ustec structured wiring panels? And if you do can you tell me if you have a panel with 8 video outlets but you have 10 outlets in the house, can you make a jumper from one of the 8 to the back input of the sat side to feed the other 8 in the can?

Second, On a subwoofer there are a left and right audio input. what if any differance would it have if i put a female rca y to 2 male rca connector on it, connected to the LFE output of the receiver?
