Good chance it's the power supply; a capacitor there, the large one, may have gone. These things age and when they go, there's noisy power to the amp circuit and ... well, that may be what you're hearing. You should check your audio wiring, too. That woofer could be picking up a 60Hz hum from the AC mains and amplifying it. Maybe you can try another spkr on same cables and see if hum is in your woofer or elsewhere. Good luck.

If you have checked the fuses which it sounds like you have, your amp may be out. Take that RCA and plug it into the other speaker. If thar she blows, treat as warranty and call the factory. If this is helpful, please post as such.

More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.
