Start by removing the vent in the center, pull out the heater/airflow control, then unscrew and lift off the radio from its sides inside the dashboard. Connect the ones holding the antenna and power first, then set aside the radio. At the front door speakers, first take off the upper door trim, disconnect the electrical connection from the tweeter, carefully pull out the tweeter while spreading apart the locking devices. To take out the speaker from the front door panel (for low speakers), first remove the front door trim panel. After, unscrew the speaker mounting screws and disconnect the electrical plug when you pull out the speaker. To take off rear speakers, lift up the back seat and take out the trim panel at the left quarter of the car, unscrew the mounting nuts, and detach the wiring from the speakers. To access A-pillar speakers, first release the trim panel covering the A-pillars, disconnect the electrical connection at the tweeter, loosen the screws holding the speaker, and take out the speaker when both steps are complete. Reinstalling each part is the same as taking it apart.
