Question, every car I've owned also have the foam on the inside of the doors as well. I've always bought after market speakers in my cars an noticed it. All of the highest end home entertainment systems have this foam all around the inside of the box , why not inside a car door panel. Respectively they obviously understand the dynamics of such enclosures and they don't have sound skins inside them , why ?

Thanks! The Adapters are made from ABS plastic so they are good to last. The rings from a closed sell foam that is made from a rubber butyl base so this will last just as long as plastic's like ABS also :D
