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.

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.

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!

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

Great product

I brought these for a 83 Chevy suburban to replace the factory dash speakers, I installed the speakers and they fit perfectly. I'm amazed at how they sound.10/10 would recommend.

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.

NVX SDBSK2 Premium Stealth Black

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

Great value

I installed these on each rear door of my 2005 Silverado. Could really hear a difference in sound quality.

Superb sound quality for such a good price!

I recommend purchasing these speakers, the construction of them is very quality. Not to mention how huge the magnets are for such a small speaker. I had them installed on my K5 Blazer and it was night and day difference from stock, I could actually hear bass and make out sounds in music I never heard with the stocks.

Perfect for 370z

These are a bit deeper than the stock 3.5s in the 370z. You have to trim about 1/4 inch off the mount and they are about perfect and sound 1000 times better than the stock speakers that are practically useless.

Great product

Great product, easy install, came with everything you need. In the process of getting an amp wired up for them.

Not bad at all

Wow, that's all I can say about these speakers. Got them hooked on a JVC head unit, these speakers sound great!!!

Cerwin Vega H735

Before installing these I didn't even realize I had dash speakers until i removed the bezel and looked. The magnet had me worried at first because of the size but had no issue installing them in my 2014 Ram 1500. Running off the factory system 8.4a uconnect radio with the standard 6 speaker system. These things sound really good. I am super pleased with my purchase and would def. recommend. These sound every bit as good as the kenwoods we put in my dads truck.

Decent

These are good speakers but are easy to blow if your driving them with any power

Excellent replacement speakers

These little things are crystal clear and loud! Tuned these in with a set of 2 way and 4 way 6x9s in my girlfriends ride and man the sound quality was amazing for just running them off the factory head unit! Affordable, well built and great sound!

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.

Sound deadening

Makes the speakers sound great and looks good to plus doesn’t blind you.

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.

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

GREAT SOUNDING SPEAKERS

WOW ! CANT BELIEVE HOW WELL THE SPEAKERS SOUND AT A VERY GOOD PRICE .

By Anonymous on March 25, 2019 Verified purchase

Amazing sound

So I blew my husbands JBL in dash speakers on his RAM and honestly I wasn’t gonna pay 180 to replace them. So I did a comparison and decided on these Cerwin Vega speakers. OMG let me tell you this speakers are loud and hit harder than his previous pair. I honestly recommend these speakers???? they are loud AF and super affordable. Also they are really heavy and great quality.

By Jenneffer on April 16, 2022 Verified purchase

Nice.

These sound great in the dash of my 1993 Dodge Daytona IROC R/T. The fact that they were inexpensive makes them even better.

By Ed on April 26, 2022 Verified purchase

Fantastic sound quality !

These sound great in my 21 Gladiator that came with the alpine 'Premo" sound system ! The factory ones are cheep speakers and you will find with the H735 the highs and Bass is sooo much better ! I installed these at the top of the dash and in the Overhead bar along with the 4" H740. One note is the factory wire connections they recommend DO NOT fit these, these tack a smaller hard shell connector and you can find them else where. Plus in the overhead bar you MUST shave down some of the rubber around the magnet to get them to fit , {about 2~3 mm } I used a dremel with the drum sanding attachment. Well worth the effort ! Along with the 4" H740's this system rocks ! Now also ordered the Metra box's with the Cerwin Vega 6.5" H7652 for the driver's knee panel to finnish out the system ! Highly Recommend !

hard to find size

Worked well for my car project! They sound good enough for me and are really good in my opinion for the price.

By Chase on November 12, 2022 Verified purchase

Great Speaker Replacement for Factory F150 Center Dash

I blew the factory center dash speaker, this CV speaker fits perfectly in the center dash for an 2016 F150. Now I have an extra one because they are sold in pairs. Sounds great and definitely an easy upgrade.

By Benjimen on May 7, 2024 Verified purchase

Factory Alpine replacement

These speakers fit perfectly in the Ram 2500 and sound so much better than the factory Alpine speakers. Running them on the factory amplifier and head unit. Worth the money. Installing the Cerwin Vega HED 4 way 6x9 speakers in the door next.

By Cedric on March 1, 2025 Verified purchase

Cerwin Vegas on point!!!

Sonic Electronix offered a great selection and their website product information was very accurate. The 3.5” speakers were a direct replacement and needed no kit or modifications. My order was processed and shipped and arrived all in less than a week!! You earned a loyal customer Sonic Electronix!!!
