Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

KLH subwoofer Model BASSBite V. Has a bad 60Hz buzz


Before you go throwing money at this problem, try to eliminate any external influences like track lighting. I myself am trying to figure out why mine makes a buzz throughout my system when the lights are on. I already replaced the variable light control with no improvement.

Bad cable ground can let airborne electronic noise into the Sub's amp.

Hi there, is there a way to get my goodmans ghc58 surround sound system to play through my virgin + box? I cant seem to find an optical input/output from the surround sound but i do have a goodmans dvd...


There is an optical output from your Virgin + box but there is no optical input in the Goomans, there is only 5.1 input. The only way to do it is to connect the re and white phono audio output from you virgin box to the red and white tv inputs on the goodmans, this will sound good but it will not give you dolby digital sound.

Crysler lhs, static buzzing noise in speakers when accellarating?


This is usually indicative of a ground loop causing noise from the vehicle electrical system. Long story short your stereo isn't grounded well enough.

There are two possible solutions:

1. Ground all components to the same point. This will reduce the potential and should greatly reduce any noise.

2. If number 1 is not possible (and it often is not), use a "ground loop isolator", available at nearly all electronics stores, or car audio suppliers. This device prevents a direct electrical connection between the two sources and will usually fix the ground loop.

make sure your dvd player is connected to the subwoofer input on the back of the unit, and make sure 5.1 channel is selected on the receiver. Also, try turning up your subwoofer with the controller
