The light comes on as soon as the sub detects a signal, it also makes a loud pop when the amp is turned on or off, but there's no sound from the speaker (other than the pop). I took it out to my shop and used the RCA input from my shop stereo and it still didn't work. After playing around with it, it started working so I took it back in the house and put it back into the theater system (Synergy Quint). It worked! Then the next night when I turned on the system, I got the loud pop, the light came on with the first signal to the sub, but no sound. Adjusting the controls to max made no difference; it was, and still is, dead.
Any ideas? Is there some place where I can download a schematic for this thing? Can I disable the auto-start feature so I'll have to turn it on when I want it in service? I'm willing to do that . . .
HELP! And thanks for any assistance here!
