I am using the small infinity satellite speakers. The instructions say for these speakers to be set to small on my receiver and the crossover to bet set at 100Hz. I have that set and I am using the y adaptor out of sub out on the back of my receiver. Both subs are located now on the left and right side in the front of the room next to my entertainment system. On the back of my subs they have an LFE or L/R input. The L/R inputs are not low frequency inputs. Since the receiver is doing all the work should the cable be going into the marked LFE inputs on both subs?
