No "Y" needed unless you are running duals as stated before. (1) rca to either left or right input on the sub. Makes no difference in sound, That is expalined in the SVS manual. I'll send you a high quaility pic od the SVS 39 PC+ panel off mine if you want? And next to M-60s (sorry no 80s but - what 2") PM me with an email if you want it. BTW my new Sunfire Grand Thheater III has 4 sub outputs, are they telling me 2 is not enough?? Tempting, my neighbors already hate me!!
