'97 Nissa Altima - how do I change the front speakers myself?

Need more info on the problem. I have seen fuel filters plug and after running for a short period the engine dies or really lacks the power to do anything. I have also seen smashed fuel lines do the same thing. Are you getting any codes? If so take care of them first. If you do not have a scanner to retrieve the codes on a gm you can jump your ALDL connector under the dash on the right of drivers seat with a paper clip. Look a the service manual and it will help you.
