Is the fuse you keep blowing the inline fuse near your battery, or the fuse(s) on your amp? If it's the fuse near your battery, you may have to install a bigger fuse. If your amp has any fuses, say 2 25 amp fuses or one 40 amp fuse, your inline fuse should be the same size as the total from your amp. In other words, if you have two 25 amp fuses in your amp, you should have a 50 amp inline fuse. If the problem is with the fuse(s) in your amp, you may want to recheck the way your subs are wired. You may be straining the amp based on the load you are trying to run. How are the subs hooked up?

The wofers are in a closure that was pre-built all I did was connect the wires, the fuse I am blowing is one on the back of the amp there are 2 fuses both 15a it is the top one and no matter what speaker I hook it to it blows. I have even tried to hook it to a regular speaker to see what happened.
