I just purchased two 5.25 Memphis car speakers. I have a factory stereo still in the car. It sounds like one of the speakers is torn. It cracks like it is. I have checked a number of times, but can not find a tear in it. I also checked to see if it was the door panel rattling, it wasn't. If I find a tear how can I fix it and get the original quality sound back, without the stinking cracking noise. thanks Det79
