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.

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.

Purchased on sale
Used these on the outside of my travel trailer. They sound amazing! I gave 4 stars on ( Look ) only because I don't really care for the grills, which is personal preference.

Great speakers!
My dad loves these! They produce a great sound and are quite loud. A really good bargain.
Too small for Volvo v-70 rear door without adjusting.

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.

Polk Audio DB522 DB+ 5.25-inch (DB 522)
Replaced the old speakers in a 2008 boat. These have good highs and put out a tight bass. You can definitely tell a difference. They do not distort when you crank it. Happy customer

AWESOME SPEAKERS HIGHLY RECOMMENDED
I bought them for my 2008 HD electra glide ultra classic to replace the factory ones
Superior sound now without running an amp which people think I have one but I don't
I'm using the factory HD head unit and they sound loud and crisp no distortion at all even at full blast ????????????.
Best of all they are water resistant.

Great RV outside speaker upgrade
Very pleased with the sound quality of these..... excellent value overall. They will fit in a shallow depth setting. So glad I trashed my factory RV speakers (1/3 the weight...speaks volumes). The audio quality is very good..... nice clear midrange and highs. Bass is a bit weak but to be expected from a 5.25" speaker! I am picky about my sound and have been pleased with this option. Build quality seems good (nice sized capacitors and good sized magnet for the speaker size).

Polk Audio DB522 DB+ 5.25-inch (DB 522) FREE Sound Dampening Kit
My cruises faring only has room for the 5 1/4” speakers and tried Kickers, and Kenwoods but at 60 plus mph the music sounds are not good. These new Polk speakers are working much better so far. I say yes give them a try and the price isn’t too bad.

Makes sense Works perfect
I put a square behind ea. door speaker and a square on the inside of each pod and it made a solid difference, especially for the pods. The music sounds better, no hint of an echo or slight vibration that I'd get before insulating with NVX SD. Pods/speaker boxes should really come insulated from the factory. Install some squares behind your speakers and you'll hear the difference.
