Hey guys,

 Just bought a used RW-10D - looks like its in great condition but for some reason it just doesn't produce any bass.  The subwoofer does turn on when I plug it in, but none of the inputs seem to work - I've tried both the Sub line, the line outs, and the speaker wire methods to my receiver but to no avail. I even tried the line outs into my ipod via coaxial to 3.5mm adapter, but I could not get any bass out of the subwoofer.

 Just wondering if the subwoofer is shot - weird considering it does power on and the light stays green.

 Appreciate any inputs -thanks!

 Was it shipped via courier? If rough handled, the wires that go from the amp to the subwoofer driver may have come off in transit. You could carefully remove the driver and check to make sure they are connected.
