Owners of other Subaru vehicles such as the Forester, Impreza, Legacy, XV Crosstrek, WRX, BRZ, SVX, Tribeca, Exiga, Trezia, Levorg and Baja may also find these DIY instructions to be helpful.

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

Removing the OEM door speaker requires a standard Phillips head screwdriver.

Then use a small flathead screwdriver to gently pry open the small rectangular shaped plastic screw cover located behind and above the chrome door opener handle.

There is a small notch on the rear edge of the screw cover.

Then move to the storage well in the armrest by the door pull handle.

Gently pry open the screw cover in the bottom of the well.

Set the screw aside in a safe place.

Then remove the Phillips screw at the bottom of the well in the armrest by turning it in the counterclockwise direction.

Move to the bottom edge of the door panel.

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

Firmly pull out the bottom edge of the door panel to release the plastic pop rivets.

Continue pulling out the pop rivet friction fasteners all along the bottom edge and both sides of the door panel.

Tilt the top edge of the door panel towards yourself while supporting the bottom with your legs.

The door opener handle cable has a black plastic collar and is located closer to the bottom of the door panel.

Pull the black plastic collar straight out of the bracket and then lift the metal ball at the end of the cable out of its socket.

Lift the blue plastic collar out of the bracket and lift the metal ball out of its socket.

Push in the release tab and slide out the electrical connector.

Then disconnect the power plug for the courtesy door step light bulb housing located at the bottom of the panel.

Disconnect the small power plug for the LED accent light located in the armrest well.

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

Push in the release tab before sliding the speaker's electrical connector straight out of its socket.

Remove the screws by turning them in the counterclockwise direction.

The OEM speaker can be replaced with aftermarket car speakers in the following sizes: 6 1/2" (6.5"), 6 3/4" (6.75") and 6"x9".

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

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

Push the small power plug for the courtesy step light bulb housing back into its socket at the bottom edge of the door panel.

Make sure you firmly push in the power plugs until you hear or feel them "click" securely into place.

Then push the black plastic collar into the lower part of the bracket.

Re-insert the metal ball at the end of the door lock rocker switch cable into the socket at the top of the bracket.

Lower the top edge of the plastic door panel down on to the lip at the top of the metal door frame.

Line up the white plastic pop rivets on the back side of the door panel with their corresponding holes in the metal door frame.

Replace the Phillips head screw into the well in the armrest by turning it in the clockwise direction.

Gently close the screw cover and pop it back into place.

Then gently swing closed the screw cover and snap it back into place.

Sit inside the SUV, close the door and verify that the door opener handle, door lock rocker switch, power window switch, LED armrest well light and the door speaker all are working properly.

Be sure to record the speaker upgrade, power window motor replacement or electrical switch change in your vehicle's service records.
