SoundSkins Rings v3

The way SoundSkins sees it, your car speakers are wasting a lot of energy. They project sound waves into the passenger compartment, but also back into the door. Their solution? The SoundSkins Rings v3 kit supplies six self-sticking butyl rubber foam strips that you cut to size and apply to the front of the speaker ring. That creates an acoustic seal with the door panel, ensuring your sound goes into the car without wasted energy. Four slim acoustic deadening panels are also included. Stick them to the door behind the speaker to reduce standing waves that can create distortion.
