If a great-sounding audio system is important to you, it’s likely that you won’t be satisfied with the factory speakers that came with your car. Upgrading the speakers can be a fairly easy task
Read the instructions that came with the speakers.Carefully use the door panel popper to remove the door panel.
Remove the old speaker from the door.Heat the Dynamat or Accumat with a heat gun or hair dryer, or leave it out in the sun to heat.
Spray glue on the metal surface of the door.Peel the back off of the Dynamat or Accumat, and using the heat gun or hair dryer, heat the material as you apply it to the metal surface.
Use a roller to press the material onto the metal so that it bonds with the surface.Drop the speaker into the speaker cavity and screw it securely through the Dynamat or Accumat to the metal of the door.
Plug the positive wire into the positive opening on the back of the speaker, and plug the negative wire into the negative opening on the back of the speaker.
Plug the other ends of the positive and negative wires into the corresponding inputs on the back of the radio.
Remove the factory grilles on the rear deck and take out the old speakers.
Drop the new speakers into the openings and wire as you did the door speakers.
Cover all exposed wires with black electrical tape.Replace the grilles over the speakers in the rear deck.
Replace the door panels on the doors.
