Are you sure that the switch is on Auto and ON? Also make sure that the volume is not more that 1/2, if is more then your low pass is too low; so you sould check your audio gear for increasing the output. Good Luck By the way you sould let the sub burn-in in low volume for a couple of weeks fefore puting it to the limit
Velodyne Subwoofer Problem?
Has anyone else had trouble with Velodynes new subwoofers? I just bought one, HGS-18. It worked the first night, but after being left on all night (it was supposed to automatically shut off), the green light is blinking (which indicates thermal overload). I turned it off and then back on, but it keeps blinking. I think I can smell some toasted electronics. I'd guess something burned up inside.
