Then gently pry out the plastic trim piece located behind the chrome silver door opener handle with a small flathead screwdriver or a pry bar tool.

Set the plastic trim piece aside in a safe place.

Next, pry out the rubber cover at the bottom of the door pull well in the armrest.

Remove the screw behind the door opener handle by turning it counterclockwise with a 7mm socket and a 1/4" drive ratcheting wrench.

Move to the armrest and remove the single screw at the bottom of the door pull well by turning it counterclockwise with the Torx T20 star bit screwdriver.

Set the T20 screw aside with the rubber cover.

Insert a plastic automotive panel removal 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 disengage the plastic pop rivets.

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

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

Gently pull the orange plastic retaining clip for the door opener handle cable from the black plastic bracket.

Push in the tabs on the two black plastic electrical connectors for the switch panel before sliding the power plugs straight out of the sockets.

Push down the release tab before sliding the gray power plug straight out of its socket.

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

I recommend buying new speakers from Amazon since you can verify which speakers will fit your vehicle and also whether or not you will need an adapter mounting bracket.

To help reduce road noise and allow your new speakers to sound their best, apply some Dynamat Sound Deadener material to the metal door frame. It will stop vibrations and rattles when you crank up the volume.

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

Push in the grey plastic electrical connector straight in to its socket.

Push in the two black plastic power plugs for the switch panel straight in to their sockets until you feel or hear them "click" securely in to place.

Swing the cable towards the door panel and pop the orange clip on to the black plastic mounting bracket.

Double check that the door opener handle cable is securely attached and test its function by pulling the handle.

Re-insert the door lock stalk in to its hole at the top outer corner of the door panel.

Lower the door panel down in to place over the top edge of the metal door frame.

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

Re-insert the two 7mm screws in to the bottom edge of the door panel and tighten them in the clockwise direction.

Gently pop in the plastic trim cover behind the door opener handle.

Lower the rubber cover down in to the door pull well in the center of the armrest.

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