Don't go without it

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

NVX SDBSK2 Premium Stealth Black

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.

Good deal

Bought a pair of kickers and they came for free, doubted them at first but it really does help in muffling the rattles from the speakers.

GOOD QUALITY AND EASIER ON THE HANDS!!!!

I got this small pack to finish my daughter's 2020 Camry after I had already used the foil-backed version. It went on just as easily and stopped the license plate and gas gap door rattle. A big plus for me was it didn't cut my hands shreds as the foil did.

Good quality sound deadener.

Not enough to cover an entire door but enough to add enough mass to make a difference. Peel and stick.
