First, remove the door panel. While the door panels vary from one vehicle to another, usually it is as simple as removing some screws and pulling the door panel outside the door. His door panel can also be considered by the clips. Gently pull the panel outside the door, so that the clips do not break. Hold onto the panel of the door and not let it fall; this could damage some of the wires inside the door.

Gently unhook the wiring of the components inside the door. There will be wiring connected to the power window mechanism, power lock controls, and stereo speaker, if your vehicle is equipped with these features. Place the door panel aside with screws or staples, so you can find it later.

Then remove your stereo speaker inside the door. As panels of car doors vary, so they do the stereo speakers. It’s very likely speaker held at the door by several screws; simply loosen and remove the speaker.
