I really hope this topic hasn't been beaten to death here. Anyways, I am wondering if my sub is hooked up for optimum performance. My receiver is a 6-7 year old Technics Dolby Pro-Logic. These are the specs: Amplifier Output Details100 Watt - 6 Ohm - 20 - 20000 Hz - THD 0.09% - 5 channel(s) ( surround ), 100 Watt - 6 Ohm - 20 - 200 Hz - THD 0.09% - 1 channel(s) ( subwoofer ), 100 Watt - 6 Ohm - 20 - 20000 Hz - THD 0.05% - 2 channel(s) ( front ) I just bought an Infinity PS-8 subwoofer and it is connected with a regular sub cable: rca type ends. Anyways, the receiver only contains a sub-out on the back. The back of the sub contains a LFE, and left-right (red-white) inputs. I currently have the cable from the sub-out plugged in the LFE input and it seems to be working properly even though the receiver does not have a LFE out. Should I be using a y-connector or whatever it is called to connect to the subs left-right inputs?? (in other words: a 1 to 2 type cable) I hope my explanation makes sense.
