I'm new around here and I was brought here in search of a problem with my Quest 10" QS10II. One night while I was sleeping, it started making a really loud humming noise. I disconnected the input but it was no good. I had to disconnect power.
Anybody know what might be the problem? I would bring it in to fix but it seems hardly worth the 70 dollars to fix a sub I got for 150 bucks 3 years ago.
