Customer Ratings & Reviews

Great deal

Got this product free with the purchase of a pair of speakers it helps out a lot looks more professional and sounds cleaner definitely give it a try for your next project.

Clean sound!

Just got a set of these and a set of infinity kappa speakers for my Scion tC, the sound is amazing! I have the powered by a hifonics 600.4 at 4 ohms, and the infinities on 2ohms. The get loud and sound good doing it!

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.

for the money

The Rockford Fosgate AR1525X2 are great. I have them in my 1989 Cherokee they are crisp loud and do very well. For their price point you can't really get a better speaker

Very Thick Dynamat

This product is very thick compared to cheap versions. Priced excellent. If you want to reduce any vibration or road sound, choose this!

Very pleased

I am glad I went with this brand. Easy application and works great in keeping my Corolla quiet and audio clean.

NVX SDBSK2 Premium Stealth Black

Thick and heavy. I was suprised with the actual quality. For the price they’re great quality

Good product

Sticky and did hook well to the cars body . Got it for free with my speakers purchase. Sonic electronix for life

Garbage

I bought these for my 96 Cherokee with low expectations to fill a void because it's a toy and they were worse than I expected. These are cheap speakers. They have mid range. Piercing, bad, highs. No lows. There is a tiny little 'bass blocker' for the tweeter.
Overall: sound quality is bad to poor
Value: Poor because I would rather buy 2 cases of Busch
Look/design: Look okay.
Durability: 3 stars because I haven't had them long. (Running on Alpine headunit at 50 watts rms max, 24 watts rms norm)
Features: Two way, full range
Ease of use: Easy. Plug them in. No crossovers to adjust

Solution: If your a RF junkie, spend the extra money on P3s or T1s. I have both in my JK and they are good for the money.

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.

Easy to use and reduced vibration, allowing clear sound coming from my door speakers.

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.

Great value!

Does a great job for the price! To replace blown out factory speakers

Great

Perfect speakers for a 1999 Pontiac Grand Prix! I bought them for my son for Christmas

NVX SDBSK2 Premium Stealth Black

Perfect fit an very fast shipping.Good list to choose from to fit my car.

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.

By Gerald on July 13, 2021 Verified purchase

Good quality sound deadener.

Not enough to cover an entire door but enough to add enough mass to make a difference. Peel and stick.

By Joseph on February 2, 2020 Verified purchase

Is what was stated

Good proformance tested well use Dally sounds great simple install

Nvx sound mat

Added 6.5 jbl gto coaxial to my front doors very easy to use clean surface and stick very easy to cut any time you door speakers add nvx mat you definitely notice the difference in the sound of your speakers it's a must best money I spent if your upgrading your speakers might as well do it right

By Big pat on June 13, 2021 Verified purchase

Bang for the buck

These speakers work great with my factory infinity sound system
Hear things you couldn't hear before
And they are right where they need to be if I decide to upgrade my stereo/amplifier

Does the Job

Good price, fast shipping, works good. Greatly improved bass while also making the vehicle quieter.

By NICK on December 3, 2022 Verified purchase

Great sound, clear highs.

Got these speakers as replacements for the pathetic 10 year old factory speakers in the front dash of my 2006 Grand Caravan and what a difference!! Very clear highs. I can’t comment on the bass since I use the high-pass filter to eliminate any bass but speakers like this aren’t meant for bass anyway. That’s what the subwoofer is for.
(Powered by the Sony MEX-XB100BT and paired with Infinity Reference X REF-5002ix in the doors and the Bazooka BT6014 subwoofer)

Good replacement speakers

Added these to a freightliner Columbia. Sounds great and the fitment allowed me to use the stock speaker covers

By Eric on February 22, 2018 Verified purchase
