I just got this receiver as a gift and need some help on hooking up to my Klipsch powered sub. The receiver has a separate sub out using speaker wires but I want to connect it to the sub's line in RCA jacks. I have seen other posts saying to connect the L and R front speakers from the receiver to the sub and then from the sub to the L and R speakers, but I also heard that you don't get the separate .1 channel response intended by doing that. Any help is appreciated.
