Owners of other Toyota, Lexus and Scion vehicles such as the 4Runner, Avalon, 86, C-HR, Camry, Corolla, iM, Land Cruiser, Mirai, Prius, RAV4, Sequoia, Sienna, Tacoma, Tundra, Yaris, FR-S, xB,  xD, tC, xA, CT 200h, ES 250, ES 300, ES 330, ES 350, IS 250, IS 350, RX 300, GS 250, NX 300 and RX 350.

The tools needed to remove the interior door panels include a plastic pry bar tool, a small flathead screwdriver and a standard Phillips head screwdriver.

The OEM door speakers can be removed with either a Phillips head screwdriver or a 10mm socket with a 1/4" drive ratchet.

Move to the top inner corner of the door panel.

Pry off the triangular shaped sail panel with the plastic pry bar tool.

Set the sail panel aside in a safe place.

Then move to the door opener handle and door lock rocker switch area.

Use a small flathead screwdriver to gently pry out the plastic trim piece located behind the door opener handle.

Set the plastic trim cover aside in a safe place.

Next, move to the door pull well in the center of the armrest.

There is a small notch at the rear edge of the screw cover. The screw cover is hinged with the hinge situated at the front of the cover.

Then use the plastic pry bar tool to carefully lift up the rear of the switch panel.

There is also a friction fastener at the front of the switch that will need to be loosened with the plastic pry bar tool.

Push in the release tabs on the electrical connectors before sliding them straight out of their sockets.

Move up to the door opener handle and door lock rocker switch area.

Remove the single screw located behind and above the door opener handle by turning it in the counterclockwise direction with a Phillips head screwdriver.

Set the screw aside next to or on top of its corresponding plastic trim cover.

Remove the two screws by turning them in the counterclockwise direction with the Phillips head screwdriver.

Set the two screws aside in a safe place.

Push in the release tab on the white plastic electrical connector before sliding it straight out of its socket.

Move to the bottom edge of the door panel and locate the notch near the front edge.

Insert the plastic pry bar tool or a large flathead screwdriver in between the plastic door panel and the metal door frame.

Firmly pull out the bottom edge of the door panel to release the pop rivet friction fasteners.

Continue pulling out the pop rivets at the bottom and both sides of the door panel.

Tilt the top edge of the door panel towards yourself and support the bottom with your legs.

Locate the two cables that operate the door opener handle and the door lock rocker switch.

The door opener handle has a green plastic collar near the end of the cable.

Pull the plastic collar out of the "C" shaped mounting bracket.

Then lift the metal ball at the end of the cable out of the socket.

The OEM door speaker is located at the bottom inner corner of the metal door frame.

I highly recommend applying some Dynamat sound deadener to the metal door frame and the back side of the plastic door panel to help stop vibrations and rattles when you crank up the volume. The sound deadener will allow your new speakers to sound their best.

To replace the plastic interior door panel, hold it near the frame and tilt away the top edge.

Lower the ball at the end of the door opener handle cable (green plastic collar) into its socket closer to the bottom of the assembly.

Insert the ball at the end of the door lock rocker switch cable (white plastic collar) into its socket closer to the top of the door panel.

Pop the white plastic collar into the bracket.

Pull the electrical connectors for the switch panel out of the opening in the armrest.

Line up the white plastic pop rivets with their corresponding holes in the metal door frame.

Push the power plug for the courtesy step light bulb housing back into its socket.

Re-insert the wires and front edge of the housing back into the opening at the bottom of the door panel.

Then gently pop in the retaining clip at the rear edge of the light housing back into place.

Replace the Phillips head screw behind the door opener handle by turning it in the clockwise direction.

Hold the switch panel near the opening in the armrest.

Push the two power plug back into their sockets until they click securely in place.

Push on the switch panel to secure the two friction fastener clips.

Close the screw cover in the bottom of the door pull well in the center of the armrest.

Sit inside the SUV, close the door and verify that the door opener handle, door lock rocker switch, power window switch, power door lock switch and door speaker all still work properly.

Be sure to record the speaker upgrade or other repair in your vehicle's service records.
