Owners of other Mitsubishi vehicles such as the Mirage, Lancer Evolution ("Evo"), Outlander, 3000GT, Diamante, Eclipse, Endeavor, Galant, Montero, ASX, Triton L200 and Raider may also find these DIY instructions to be helpful.

The tools needed to remove the door panel include a small flathead screwdriver, a Phillips head screwdriver and a large flathead screwdriver or an automotive panel removal tool.

No tools are needed to detach the OEM speakers from the door frames.

Gently pry out the square screw cover located behind the door opener handle and next to the door lock switch.

Set the screw cover aside in a safe place.

Then move to the door pull handle in the center of the armrest.

Gently pry open the hinged screw cover at the rear edge with the small flathead screwdriver.

Then remove the screw below the door pull handle in the center of the armrest by turning it counterclockwise with the Phillips head screwdriver.

Set the two screws aside in a safe place.

Set that screw aside with the other two screws.

On some Lancer trim levels, the sail panel may contain a tweeter speaker that needs to be disconnected.

You might need to press a release tab before pulling the plug out of the socket.

Insert a large flathead screwdriver or an automotive panel removal tool in between the bottom edge of the door panel and the metal door frame.

Firmly pull out the pop rivets on the bottom edge of the door panel.

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

Tilt the top edge of the door panel towards yourself while supporting the bottom edge with your legs.

The door lock and door opener handle cables can be detached from the door panel in two ways.

One way is to remove the two Phillips head screws by turning them in the counterclockwise direction and then pull off the entire assembly.

First pull the black plastic collar near the end of the cable out of the bracket.

Then swing the cable away from the door panel.

Pop the green plastic "C" shaped collar off the metal bar at the end of the cable.

To disconnect the two electrical connectors, press in the release tabs before sliding the plugs straight out of their sockets.

Then pull the speaker straight out of the door frame.

Press in the release tab on the speaker's white plastic power connector before sliding the plug straight out of the socket.

I'd recommend purchasing new speakers from Amazon since you can verify that they will fit your vehicle and whether or not you'll need a mounting adapter bracket or not.

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

Push the small white plastic power plug for the door lock switch straight in to its socket.

Re-insert the metal bar at the end of the door lock cable in to the top green plastic socket.

Pop the green plastic "C" socket over the metal bar.

Repeat the process for re-installing the door opener handle cable in to the bottom part of the bracket.

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

Firmly tap in the pop rivet fasteners all along the bottom edge and both sides of the door panel.

Line up the friction fasteners on the back of the sail panel and firmly push it back in to place.

Re-insert the Phillips head screw below the door pull handle at the center of the armrest and tighten it in the clockwise direction.

Re-insert the Phillips head screw behind the door opener handle and tighten it in the clockwise direction.

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