1. Using a flat screwdriver carefully remove the door-pull handle cover
2. There will be 2 screws you will need to remove. Take them off
3. Now you have to pop the door card from the door. You can use a flat screwdriver again to help you pull the door card out, but be careful not to scratch the door too much. Start from the bottom, and work your way up
4. Once done, unplug the speaker, and you can put the door card way.
5. Remove the sound-deading foam
That's it.
