Yes, stinger ultimate sound dampening, it's also in areas inside of the door too. You have to be very careful when applying it on the inside, and be mindful of the window track/pattern. It will make the doors heavier, denser, and less road noise too. Stinger ultimate ftw!!!

The ac spike subs sound great 👍🏼👍🏼
My A4 B9 2018 has rattles in every door from cables ig, does this helps with that?
