This automotive "how-to" guide was specifically written to assist owners of the 2007 to 2012 Mazda CX-9 crossover SUV in removing the front interior door panel in order to add soundproofing, replace the front speaker, or replace the power window motor.

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 and a ratcheting wrench.

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

Pry Off Side View Mirror Panel
The first step is to use a small flathead screwdriver to remove the rectangular trim piece below the door handle that hides a Phillip head screw.

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

Pry Off Arm Rest Side Cover
Next gently pry off the triangular trim piece just above the front top part of the interior door panel that covers the side view mirror power connector and it's fastening bolt. In some vehicles, this plastic trim piece would house the tweeter speaker.

Use the small flathead screwdriver to pry off the long rectangular trim piece on the side of the armrest. 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.

Releasing Door Fasteners
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.

Window Motor Mounting Point
Try to avoid pushing on the round white plastic piece located behind the power window motor. 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.

Tighten the two 10mm screws into the side of the armrest. I found it easier to replace the 2nd 10mm screw in the deep well by using painter's tape to secure it to the socket on an extension bar.

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