Why did my sub stop working?

[Kasey11]

I have a rockford fosgate P300-12 powered sub. I drove over a set of railroad tracks going about 25 mph and i heard a weird crackle noise come from my sub and it wont turn on now. I checked all the wiring and it is all connected but the sub itself wont turn on. What might be the Problem?
