yea, it's permanent. if you have these in your car and plan to sell the car, they're either staying in the car or you're replacing the entire factory door panel. for most people, they do it because they're keeping the car for a while. it's not for everyone. alternatively, you can have kick panels made for mid bass. before the door panels, i had 8" Dynaudio MW 172's in my kicks.
