Mine has a tiny bit of hum. However, once there is a signal into it, the hum disappears. Check your cabling to the sub. It is picky about interconnects and speaker wire.
The amp may be causing the hum if too close to the sub? Isolate the amp from the sub.
Final note: Play with the volume control.
Once you lessen the hum, never mess with it again and you'll have a killer sub. I never even turn mine off.
