heck to see if a positive and negative speaker wire are touching anywhere in your car. If none are touching see it the pos and neg wires in your subs are set up right (pos on amp to pos on speaker neg on amp to neg on speaker) it they are conected right just flip them to see (sometimes we think they are correct but they are not) if that doesnt work go to your local sterieo shop they might be able to see the problem.
