Begin by unplugging and separating the negative
Battery Cable to remove the rear shelf speaker. After that, pull out the rear
Seat Cushion, take out the rear seat back and remove the rear shelf panel. With that done, remove the four screws holding the speaker, take out the wire harness and remove the speaker from your car. Put the wire connector into place, set the speaker in the vehicle and tighten it with the screws around the speaker frame. Then, add the rear seat panel, the seat back and the rear seat cushion and finally attach the battery negative cable.
