Great improvement over stock
I replaced the factory speakers in the front of a Coachman motorhome with these speakers. They fit the old speaker location with no modifications and greatly improved the sound. I used the original grills that came with the motorhome so the instilation looks stock.

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.

Excellent Quality
I purchased these to replace the stock door speakers in my 2007 Honda Accord. They fit perfectly and sound very nice. They really need an amplifier if you want any sort of bass out of them, but for mids & highs they're fine on a factory deck. The best part about these is their construction; they are very solid and come with a rubber gasket already applied to the mounting surface. I just feel bad that they hide behind grilles because I love the way they look. I'm quickly becoming a fan of Rockford Fosgate.

Good speakers
They are great for the price. Crisp and have ok bass. My old car only has 2 speakers overall. So I know these will perform much better in greater numbers and with a better stereo.

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.

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.
