SOURCE: Loud humming noise from subwoofer

if it is a powered sub you should lift the ground. you can do this by adding a three prong to two prong adapter. you know, like when you go to plug something in and the cord your plugging in has three prongs and the outlet your plugging in to only has two. it doesn't have the hole for the ground so you go get a little grey adapter that has three holes on one side and two prongs or tabs on the other.if that doesn't take the hum out (actually, is keeping the hum from getting in) you have a problem with the amplifier.

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.

SOURCE: Subwoofer thumping when turn on

Your subwoofer is not getting enough power, or it is grounding out due to a bad connection. What is powering the subwoofer? You might want to consider buying an AC to DC power inverter and a car amplifier to power your subwoofer. You connect the AC/DC inverter to your amp the same way you would in your car (+) to (+) and (-) to (-). The only other thing you will have to do is run the remote wire to the (+) on the amp. You can buy the AC/DC inverter at radioshack for $49.99, and all you really would need is a 200watt max amplifier and that would cost you about $10-$20.00 for a cheap one.

SOURCE: subwoofer clicking noise

Hi I am afraid it sounds like exactly the same problem I had, Namely the PSU(power suplly unit) is failing, This is a common fault (by reading loads of forums) I contacted KEF today about mine and they say the probably wont be able to source any more spares(due to so many having thuis problem no doubt) So I would suggest contacting the people you bought it from,Under the consumer protection act you should expect an electrical item to "Last a reasonable amount of time" .Mine is 3 years old and I do not consider this to be a long period so kick up and you should be entitled to a repair or at worst a partial refund.Look here basically the same Sub.

I'm getting a loud "popping or clicking when i plug the sub in. also i noticed the green light comes on immediatly when the loud popping begins. the loud popping dosen't stop untill i unplug it


What's feeding it? The sub comes on automatically when it senses a signal, which seems to be what it's doing. Perhaps the loud clicking is originating at the other end of the cable.

Jbl 12 subwoofer loud noise


Hiya, could be the power supply or possibly the amp circuit that has gone. If there are electronic guys in your area, they should be able to sort it out relatively easily. Get a quote first, make sure it is in economical repair as well, but it can be repaired

My JBL PowerBass PB12 makes a continued loud sound when it is on


Have you tried turning the gain down before turning it on. If that works, it might be the internal amp picking up noise somewhere. Maybe even a bad ground. Either way there are only a few things you can try before complaining to the manufacturer or replacing it. Changing its location might help and if it does might indicate RF interference. You can also try running it through a power strip, one equipped with a filter (these are fairly common). Good luck

JBL PB10 subwoofer, it makes a loud burp noise when it comes on.


In the industry - It is called "Turn-On Thump".

There are some manufacturers that eliminate components like noise filters on enry level lines to save money.

There is no way to lessen this noise without ripping the amplifier apart and having a technical knowledge of the way amplifiers work. It would involve hard-wiring a slow charge capacitor in the turn on line so it gradually builds power instead of getting it all at once.

Thanks for using FixYa - a FixYa rating is appreciated!!

If your wire connections are normal then the problem is due your woofer speaker. Its your subwoofer circuit error and must be repair thru replacing the damaged Component in the circuit
