Owners of other Mazda vehicles such as the MAZDA2, MAZDA3, MAZDA6, MX-5 Miata, RX-8, MAZDASPEED3, MAZDA5, Tribute SUV, and CX-7 crossover may also find this guide to be helpful.

The tools needed to remove the interior door panels of a Mazda CX-9 include a small flathead screwdriver, a standard Phillips head screwdriver, a 10mm socket with an extension bar, a ratcheting wrench and either an automotive panel pry bar tool or a large flathead screwdriver.

The OEM front door and rear door speakers are 6" x 8" but 5 1/4" speakers will also fit with an adapter bracket.

Remove the screw with a standard Phillip head screwdriver and set it aside in a safe place.

In some vehicles, this plastic trim piece would house the tweeter speaker.

Behind the trim piece on the side of the armrest, you'll see two 10mm screws.

Remove them with a 10mm socket and extension piece on a ratcheting wrench.

Then gently pull the lower part of the door panel away from the door frame to release the plastic friction or "Christmas Tree" fasteners.

Don't pull too hard since there are several power connectors that need to be released along with the door handle and lock switch cables.

Remove the courtesy light bulb cover, remove the bulb, and push the bulb socket back through the rear of the door panel.

I recommend buying new aftermarket speakers from Amazon since you can verify that the speakers will fit your car and whether or not you will need a mounting bracket.

Push the release tab on the light grey speaker power connector and pull it off the rear of the speaker.

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

Remove the old power window motor by loosening the three 10mm screws with the socket and ratcheting wrench.

It might move out of place and the new window motor will be harder to install.

If necessary, remove a few of the 10mm screws on the black inner door panel and hold the round white plastic power window cable reel in place from the other side while you push on the new power window motor.

Move to the bottom of the door panel and line up the white plastic friction or "Xmas Tree" fasteners with the holes on the door frame before pushing them together.

Snap the trim piece on the side of the armrest back into place.
