Double checked..
Speaker A and CD selected, volume up []
Subwoofer cable from "subwoofer out" on receiver to "left line in" on sub.
Phase @ 90, lowpass @ 80, power on, side volume control in the middle.
Green light, power set on auto.
Music starts > power light is green, no music for ~ 5 minutes > power light is red.
Gently touching the cone I can feel there is absolutely no movement and no sound.
One troubleshooting guide I found suggested if you have power on and remove the subwoofer cable from the back of the receiver (subwoofer out) and tap on the end of the connector on the cable you should hear something coming from the sub. Not..
