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?
 
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.
