Solved! Definitive Super cube III subwoofer doesn't seem to play anymore

[beason13]

My Super cube III doesn't output any sound anymore. The red light is on, I checked the fuse and it looks ok, but I just don't get any bass sounds anymore.
In the past ,during a movie or football game, I would get startled by a loud bass sound...not anymore. Any ideas?

What all is connected and how the the connections being made?

If ur unlucky, it burned out, needs fixing$$.

If ur lucky, something changed, something moved.

First thing I would do is, go through receiver initial setup where it sends signal to each speaker for verification.

After you check the receiver set up to make sure that the sub out is turned on then you can try a different cable from the sub to the receiver.
The most common problem is a bad power amp. Call Def Tech customer service. They may sell replacement amps at a reasonable price.
