Owners of other Mazda vehicles such as the Mazda2, Mazda3, Mazda5, CX-3, CX-5, CX-7, CX-9, and the MX-5 Miata may also find these DIY instructions to be helpful.

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

To remove the OEM door speaker, you'll need a 10mm socket with a 1/4" drive ratchet.

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

Set the trim cover aside in a safe place.

Then use a flathead screwdriver or a plastic pry bar tool to remove the rubber cover at the bottom of the door pull well in the center of the armrest.

Set the rubber cover aside in a safe place.

Move to the top inner corner of the door panel.

Use the plastic pry bar tool or the flathead screwdriver to gently pry off the sail panel.

The sail panel is held in place by two plastic pop rivets. It resembles two triangles attached by a small plastic strip.

Remove the screw located behind the door opener handle by turning it counterclockwise with a Phillips head screwdriver.

Set the screw aside with its corresponding plastic trim piece.

Set the screw aside with the rubber cover.

At this point, you should have removed two plastic pieces, one rubber cover and two Phillips head screws.

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.

Gently lift the top of the plastic door panel off the upper lip of the metal door frame.

Locate the grey plastic and white plastic electrical connectors on the underside of the switch panel.

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

(If any of the white plastic fasteners remained attached to the metal door frame, use a pop rivet removal tool or a flathead screwdriver to pry them out. Then re-attach them to the back side of the plastic door panel.)

The OEM speaker is held in place by four 10mm bolts. Remove the bolts by turning them counterclockwise.

You can replace the OEM speaker with aftermarket speakers in the following sizes: 5 1/4" (5.25") and 6 1/2" (6.5").

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

To re-install the plastic door panel, hold it near the door frame and support the bottom edge with your legs.

Push the plastic assembly for the door opener handle, door lock switch and the two cables back in to the bracket on the back side of the door panel.

Push the two power plugs back in to their sockets on the underside of the switch panel.

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 screw at the bottom of the door pull well in the center of the armrest by turning it clockwise with the Phillips head screwdriver.

Re-insert the rubber cover back in to the door pull well.

Gently snap in the plastic trim piece behind the door opener handle.

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