This automotive maintenance tutorial was specifically written to assist owners of the first generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Terrain in taking off the plastic interior door panels in order to upgrade the OEM speakers.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Acadia, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

The tools needed to take off the door panel include a small flathead screwdriver, a 7mm socket, an 8mm socket and a large flathead screwdriver or an automotive panel pry bar tool.

The OEM door speaker is held in place by three 7mm screws.

The first two steps are to lower the power window all the way down and open the door.

Then gently pry out the plastic trim piece behind the chrome silver door opener handle with the small flathead screwdriver.

Set the plastic trim panel aside in a safe place.

Move to the opening below the arm rest and pry out the plastic screw cover with the small flathead screwdriver.

Hold Panel Near Frame
The OEM door speaker is held in place by three 7mm screws.

If any of the grey plastic pop rivets are still attached to the metal door frame, pry them out with a pop rivet removal tool.

I recommend buying new speakers from Amazon since you can verify that they fit your SUV.

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

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