Subwoofer "thumping" w. no audio feed
You need to check your ground connection. If there is a bad ground there will be feedback to the amp and it will just sit there and loop back with the Thump, Thump, Thump sound. I had to wire my amp's ground all the way back to the negative battery terminal. It was a pain but I have never had a problem since :)

Before you blame the speaker one simple test needs to be made, if you have not done so already.
If one remaning speaker has full volume output, swap one of the 'defective" speakers to that same channel the "good" speaker was attached to, and see if the output drops.

Thumping when not hooked up
First thing to check are signal cables but broken fuse telling me that problem is 99% in sub power supply unit or the amp.If you have a voltmeter and if you KNOW how to do it dissasembly it and check DC voltage on a speaker conntacts.If there is any DC present your amp is worn out.But this can be VERY DANGER because 220/110V is there so if you are not 100%sure that you can do it DON'T!!!

How to factory reset a JBL onbeat awake
For the JBL Awake
I just had the same issue and i found a way to solve this :
1. Unplug the power supply
2. Plug it back while holding the [ON/OFF] button
3. The screen shows “UP9” again
4. Do the update with the JBL Music app (I did it with my old iPhone 4s plugged on the 30pin connector)
5. Finish the firmware update ... until the app tells you to unplug the power before restarting the device
(Sorry for my bad English, i’m French)
