I'm currently using an old Klipsch KM-RSW powered sub in my small office system. It sounds ok, but occasionally just cuts out for a while, then back in again. What are the main things I should check to fix that?
I heard those cause that kind of an issue. My main amp seems to have one that cuts each channel in and out independently, but it happens quite rarely, and the thing's such a PITA to dismantle that I haven't bothered fixing it yet.
