I just got an SVS last week and absolutely love it. I have it set to auto like my previous sub. For some reason, the sub doesn't kick on unless there is a huge amount of bass like from a dvd. If I'm watching television or playing a video game it will shut off even if I'm watching a music channel which should be enough bass for it to kick on. My previous sub would kick on without a hitch so I don't know why the SVS wouldn't. The gain knob is set to 3/4 and my receiver is at -10.
