Check the fuse which tends to blow frequently.

The power supply is working but it is possible that there is no supply to the SUB WOOFER amplifier. It is important to remove and open the unit to probe and confirm.
It can be failure of the inline fusible due to a faulty output driver.
Finally check the subwoofer using a AA cell.

If there is power to the woofer then a signal input must power the woofer to work. So feed a test signal or a audio siignal from a DVD and if there is no output then the AMPLIFIER section had faults.
Unless the sealed unit is opened it cannot be tested to confirm if the output , the input to the AMP or the power supply has failed.
Check if there is power to the output section to confirm.

with nothing connected and the sub turned on....Most subs buzz when the circuitry starts to fatigue. The last time I heard this ..the repair ended up being one of the two fat capacitors inside the sub. I have a means of testing this,,you may not. I am a repair shop with a bit of experience in component level board repair.

I too am looking for the solution, I'm hoping I have the wrong power cord which is sending too much power to the sub, my next attempt will be to just up the AMP on the fuse b.c hey it's broken anyway

This happens to amps/speakers in general. It's not specific to your system. It's caused by momentary changes in power. Please read the following for more detail: Amp causes speaker pop

They could be defective but also the charger could be falsely indicating the batteries are charged when they aren't.

This sounds more like a low power situation. The voltage to the unit might be low, and should be measured.
As far as I know, there's no reset for the unit. Disconnecting the power should reset it, if there is one.
