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.

SOURCE: Headphone jack works, sub fuse good, no sound to speakers

i gave a very long and detailed response to this but i didnt submit it correctly so its gone now !
sorry about that,
bottom line was......, it is probably your audio source.
please try a different speaker or audio source .
watch out for air leaks and rattles putting the bassbox back togther. or it will sound rubbish .

Hum is tough. It is often caused by quite a variety of things. First, address the basics:
1. Make sure that none of your signal cables run near to power cabels.
2. If possible, feed all power from the same receptacle.
3. If your plugs are not polarized, try reversing one at a time.

If none of those basic checks uncovers your demon, verify the path of the noise by disconnecting the signal from the preamp at the input to the sub. If is still hums, then look closely at the power feed to the sub, More likely, the hum will stop (along with the music.) In this case, try breaking the shield ground at the sub input (e.g. with a ground isolation adapter.)

You should also confirm that the hum is limited to the sub. Subs tend to exaggerate hum because playing signals in the 60Hz is their forte. So with the sub turned off and bypassed, listen for the hum in your main speakers. If it is there, too, then start checking your sources. Remember, even a source device other than the one selected for play could be the source ... completely disconnect each source at the preamp to track it down.

The subwoofer output on my Kenwood VR-606 has suddenly stopped working. I have tried the "setup" several times, turning the subwoofer off and back on. Also, when I first power up the system, it emits a low...


It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps.
Cheers, Don.

Major hummimng noise when sub is connected to receiver.


Is the hum in the receiver-attached speakers or the sub?


Self-powered sub?


How is the sub attached - RCA or speaker-level?


Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.


If it hums with the sub attached, unplug the sub's power cord. Differences in AC ground potentials will generate hum across linked devices.

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

This is a common problem.  The potentiometer is damaged and needs to be replaced.  Potentiometer is a fancy name for volume knob.  It's a $5.00 fix if you know what you're doing.
