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.

Excellent sound and build quality
Installed these to replace the factory speakers in the front of my Tacoma. Install was easy with the adaptors supplied by Sonic. The sounds quality is fantastic, much more clear mid bass than the factory equipment. I’m sure they will be even better once I get an amplifier in the truck.

prefect fitment
I have a 2023 Toyota Camry LE with a 7-inch screen, and it fits perfectly. This is the part you need for your Camry, for any year model that looks the same, and it sounds great. It's a must-buy.

Great deal with Sonic
I recently upgraded to the Hertz C 165 car speakers, and I couldn't be happier with the decision. The overall sound quality is excellent-balanced, powerful, and crystal clear across the highs, mids, and lows. Vocals come through sharp and detailed, while the bass delivers a solid punch without being overwhelming. What impressed me most is the clarity at higher volumes-no distortion, just clean performance that really elevates the driving experience. These speakers make every genre of music sound fuller and more immersive, and they're a huge step up from factory-installed options. If you're looking for speakers that combine quality craftsmanship with clear, reliable sound performance, the Hertz C 165s are a fantastic choice.
Pros: Excellent overall sound quality - well-balanced across highs, mids, and lows Crystal clear performance, even at higher volumes with no distortion Sharp, detailed vocals that stand out in any track. They fit perfect on my 19 vw jetta gli.
Cons: None
