So I came home to my sub making this humming noise. I unplugged everything and the sub continues to hum. It does get a little louder as I adjust the knob but only after a certain threshold.
Not entirely sure what's going on here, quite possibly there was a surge when I was at home (that's what I get for not plugging the sub into a surge protector).
My question is: can I fix this myself or will it cost an arm and leg for a shop to do it? Am I better off replacing the whole unit?
