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 :)

4 out of my 5

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!!!

Problem with your JBL BoomBox2 speaker (or similiar) ?

Just found this out, after crazy searching & brainstorming. So if your speaker suddenly goes silent or sound comes and goes, you can check this out: At least the JBL BoomBox seems to have this integrated in its architecture so there's nothing we can do about it, complain to JBL : ) But to the problem: if the SOURCE of music/sound is too low, then the speaker may go into a "sleep mode" - silent. So ensure always your SOURCE of sound, connected to the speaker, has volume at least 80% to avoid this problem. Hope this helps & no one needs to ditch and buy a new one ! : )

JBL PRX 625 Speaker. How can we fix the overheating in the speaker please?

Question edited for clarity. Undo the screws at the back and look for a cooling fan. There is something in the centre that looks like one. Or contact JBL direct and put in a warranty claim. The overheating issue seems well documented. Although you shouldn't have to, you could easily cut a vent hole with filter at the base and a 4" case fan above the amplifier to pull out the hot air. 3 x 500 watt inside is bound to create heat. https://www.google.com/search?q=jbl+prx+625+overheating+problem ..

My JBL e45bt wireless headphones won't turn on. I've tried charging them overnight, but i doesn't help at all. How do I get this fixed?

If your JBL E45BT wireless headphones will not turn on, there could be a problem with the battery or the charging system. Here are a few things you can try to fix the problem:
  1. Make sure that the headphones are charged. If the battery is completely drained, the headphones will not turn on. Try charging the headphones for at least 2 hours to see if this resolves the issue.
  2. Check the charging cable and port to make sure they are working properly. Make sure the cable is securely plugged into the headphones and the power source, and that the port is free of debris.
  3. Try a different charging cable or power source to see if the problem is with the cable or the power source.
  4. If the problem persists after trying these steps, it is possible that there is a problem with the battery or the charging system. In this case, you may need to have the headphones inspected by a technician to determine the cause of the issue.
If you are not comfortable troubleshooting the problem yourself, it is recommended that you contact JBL customer service for assistance. They may be able to provide further guidance or offer repair options.

I have a JBL SUBWOOFER MODELPSW-1200 that hums as soon as it is plugged into the wall plug, there are no speaker wires connected to the subwoofer!

The hum might be caused by the main semi-conductor device that produces the sound. Of course a capacitor might look normal and still cause the problem. The only way is to replace the big ones in the unit.
