Hi all, I'm new to the forum so here goes. How should I connect my equipment? I don't know which is the most optimal way to connect the powered fronts and my powered sub. This is what I have: Klipsch RP3 (fronts) - Line Level In/Out, LFE In/Out - Speaker level inputs (2 sets/biwire) Klipsch KSC-C1 (center) Klipsch KSB1.1 (rear) Powered Sub - Line Level In w/ LFE on/off switch - Speaker level inputs/outputs Harman Kardon AVR320 - preamp outs for all channels When I just had a standard front speaker I would use a speaker level connection from my receiver to my sub then more speaker wire from the sub to my fronts. Now I have these line level in and outs, preamp outs, LFE in and outs and it's confusing me. I'll need all the advice I can get. I'm obviously not in the know how. Thanks in advance!
