So I have two of these subwoofers. One works perfectly fine. The other one still works but at a low volume. Soon as you bring the input trim to 12 o’clock it’s starts clipping red. I have attached some pictures to see if anybody could help me. I really like these subs. They do what they have to do for my dj setup in the basement. Nobody in the New York area wants to touch a behringer. They say it’s trash and disposable. I know it’s cheap but it works for me. Hope someone can steer in the right direction.
