Very good stuff. Does its job. I got cut a couple of times though lol.
Installing iis pretty easy.....just peel and stick.
I only used 4 sheets for both doors but I am planning to use more. Midbass sounds great and there are no rattles. I did notice some rattles prior to installing the sound deadening.
Like I said before, I will be installing more sheets soon. Even though it sounds good the way it is
