I have a Denon 3808ci with 2 Source Technologies (I don't know if they are still in business) subwoofers (model KG-5150 2x). I did not install this system. The installer connected the subs to the Denon SW out port with one black and one red wire that seem to be connected TOGETHER to the male RCA jack (the receiver has only one Out) and another pair of red and back wires (twisted together) connected to the Denon Singal Ground screw. Seems odd to me. Is this correct? The sub has a green and red light. The green light is on but no sound is coming out from the sound level tests.

Any advice would be GREATLY appreciated.

Kind regards,
John Gormally, Springfield, Mass.

AVR's with one Subwoofer output (Black Jack) can utilize a single RCA Cable to the Sub-woofer. However, most active subs have both Left & Right Channel audio Inputs so a Y-Female In to Twin Male RCA Out adapter cable is required. Alternately, you can utilize a Male Y cable, at the Denon AVR, and then a stereo RCA from there to your Subs stereo inputs.

The Denon AVR Bass should be configured as "LFE + Main" in the speaker setup section and most system the crossover should be set to 80Hz
