1. Turn off the engine and disconnect the battery. This will prevent any electrical accidents from happening while you're working.
2. Remove the trim panel around the stereo. There are two screws on either side of the panel that you'll need to remove with a Phillips head screwdriver. Once the screws are removed, the trim panel can be pulled off gently.
3. Remove the four bolts that hold the stereo in place. There are two bolts on either side of the stereo. You can use a ratchet or a socket wrench to remove these bolts.
4. Disconnect the wiring harness from the stereo. There is a single wiring harness that connects the stereo to the car's electrical system. To disconnect the harness, press down on the small tab on the side of the connector and pull it out.
5. Remove the stereo. Once the wiring harness is disconnected, you can simply pull the stereo out of the dashboard.
Note: If your 2002 Honda Civic has a factory-installed security system, you may need to enter the security code in order to remove the stereo. The security code can be found in the owner's manual or on the vehicle's VIN sticker.
