I have a Denon 1804 receiver with Definitive Tech Pro Cinema 60 set of speakers. The recommended setup is to hook up the front left and right surround speakers to the subwoofer then hook up the sub to the receiver. Now, the Denon 1804 has only one "jack" for the subwoofer (a LFE link I believe.) The subwoofer has 3 jacks, the LFE and the left and right inputs. Question is, how do I hookup the subwoofer/speaker combo to the receiver and have it recognize that I have a 5.1 system? Would I use a Y-RCA cable to go from the receiver's LFE out to the sub's left and right in? If that is indeed the solution, what do I do with the LFE in on the subwoofer? Is that necessary? Also, how would I get the receiver to recognize that it's 5.1 if the two front surround speakers are going through the subwoofer channel on the receiver? Thanks for your help, I'm quite new at this.
