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.

Nice coax
I'm very pleased with these 6.5 coaxes. They are paired with the 6.5 components of the same series. Have them running off a Kenwood x700.5 and they sound great!!! I decided to use the flush mounting brackets(included in the box) and all 4 6.5s all are snuggly nested in the NVX Baffles I bought right here at sonic.

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.

I've bought Hifonics speakers before so I know their sound quality is great for such a low price. Another great set of speakers. Very clear.

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.

will not fit a 97civic
This is a good-sounding low-cost speaker, but be careful they have a large mounting ring that will not fit in the door of a honda civic without being trimmed.

I installed these in my 2004 Jeep Grand Cherokee, they needed to have holes in order to fit my application. That being said, they sound great and are an extreme value.
