Perform Do-It-Yourself auto maintenance at your own risk. You can kill or injure someone or damage the car. Work or raise an auto only on a level, concrete floor. Do not go under any auto unless you are completely certain that it is secure. You and only you, are responsible for your work and safety
Front and rear, left and right is ALWAYS related to the car itself, NOT how you are facing it:
LEFT is always the DRIVER side.
RIGHT is always the PASSENGER side.

The older mid-range door speakers in the RDX are known to fail. If your door speaker sounds tinny or fuzzy, it may need replaced. The old speaker was part number 39120-STK-A11. They have been replaced by a new part with a superceded part number. The new speaker is about $26.00 and the new part number is 39120-STK-A12.
Tools and parts needed:
1. Plastic auto body prying tools (a few bucks at Harbor Freight). Plastic is less likely to damage or scratch anything.
2. Cross-tip screwdriver.
3. Needle-nose pliers.
4. Mid-range door speaker 39120-STK-A12
5. Eye protection, face protection, gloves and protective clothes.
Plastic prying tools are about 15 cm long and look like this:
Begin removing the door panel by gently prying at the leading edge of the tweeter to pop it's nylon fastener out. It will remain attached by the wire plug:
Compress the spring tab on the wire plug, on the back of the tweeter. Gently pull it out of the tweeter and remove the tweeter and set it aside.
At the bottom of the interior door pull handle, pry down the hinged plastic cover and remove the lower door pull screw. Put it in a labeled baggie.
Behind the interior door release handle, pry at the bottom of the plastic cover to remove it.
Note the position of the 2 black and 1 silver upper door pull screws. Remove them and place in a labeled baggie.
Now the door panel is ready to be unsnapped. Locate the prying notch at the bottom of the door panel. Insert a plastic pry tool and pop the lower nylon fasteners loose. Using your gloved hands, work around the door panel pulling the fasteners free. Pull just far enough to free the fasteners -- do not stretch the cables and wiring behind the panel.
The top of the door panel rides in a slot in the top of the door frame. Pull and bump upwards on the rear of the panel to ease it out of the slot. Then work forwards pulling it up. Be mindful of the cables and wires that are still attached.
When the door panel is free, hold it a few inches away from the door and use needle-nose pliers to release the 4 spring clips holding the inner latch release to the panel. Gently let the latch and cables hang free.
Gently squeeze the tab on the window/lock power plug and disconnect it.
Now the trim panel will be free. Set it aside. Here is what the inside of the door with speaker looks like. It is a good idea to use some old house wire to support the loose latch/cable assembly.
