Do you have an amplifier in the car? If you do, make sure the gains aren't maxed out. If you don't have an amp, and you're sure the radio is wired correctly, set your treb/bass to flat (0). If your speakers still distort, go to your local shop and have them listen to it. It's likely that they're blown (W/O amplifier) and need to be replaced. Good luck.
