    Depending on the model, the fuse should be right on the back of the sub on the amp plate. If there isn't one on the back of the amp, then it probably doesn't have one and that isn't the problem. If it is still under warranty, opening it up will void that for sure. If it isn't, there's a slight chance there may be a fuse inside on the amp board, but no guarantees on that. If you don't have the manual, check around the web to see if you can download it and see if it says anything about a fuse. More likely than not, a capacitor failed, especially if it is older, and this is something that can still occur regardless of the presence of a fuse.
