Hi,

Wasn't sure if i should put this under the PC speakers section cause maybe its a general problem with non-pc speakers aswell, but my problem is this.

No matter whether the volume is set to 0 or i unplug all the jacks from my pc...my sub/amp hums constantly...

Its a 5.1 system but not the most expensive...

The humming is actually the sub vibrating constantly.

Is this due to some crappy components in the amp? and is there anything i can do to fix it

Thanks
