Don't go without it

The following review is for SDBSK2, which is a part of the bundle you are viewing.

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

The following review is for SDBSK2, which is a part of the bundle you are viewing.

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.
