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

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.

The rookie diy’ers answer to wanting quality sound without breaking the bank

I’m just getting back into building my own car audio system and knew I wanted Cerwin Vega speakers but like many folks , my wants exceed my budget so I decided to try out the xed 6x9 coaxial 3 ways instead of some of their higher end products to replace my stock system and I am kicking myself for not making this decision sooner cause WOW!! Like night and day! And this is without them being connected to an external amp, just the head unit 80x4 preamp which is probably 20x4 rms but the sound quality of the xed 6x9’s is perfect for the diy’er that wants to upgrade from stock themselves ,cause they are basically plug and play, and still have gas money to go enjoy a cruise with the windows down to show off that quality Cerwin Vega Sound that you eaened

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.

Cerwin-Vega XED693

Awesome speakers sound great didn't need to run external amp used amp on Kenwood stereo and the sound quality is awesome went to 6 and 1/2 to 6 by 9s and two more six and a half and to two and a half all the same exact Cerwin Vega line all the budget-friendly Cerwin Vegas I got one app pushing 1 -8-inch sub also by Cerwin Vega the amp is a stealth 1 channel amp and the sound quality for the whole setup is awesome can't get any better

good quality

I replaced my MB Quartz 6x9 with these and I'm sold. Vega has always been a quality speaker even for the base model like these.

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.

Nice

Look great, sound great, I actually installed in my boat and they have held up as well or better than some of the junk marine speakers I have used.

By james on April 8, 2020 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

El sonido es claro quedan perfecto en un honda accord 07 sin adaptadores

does not fit dodge magnum rear deck speaker without modification

tried to install these today in my dodge magnum rear deck. they will not fit without modifying the stock opening. a 1/4 inch spacer may work but height may be an issue. i had some 1/2 inch spacers , but there is not enough room, height wise. nice speakers though, great price. definite upgade from my stock boston accoustics speakers that are buzzing a bit.

By joe on December 2, 2021 Verified purchase

good buy

Good price and sound great, would probably sound even better if I had them on an amp

2022 Ram replacement speakers

XED693 speakers fit perfectly in the stock location. I reused the original speaker screws with no issues.
The sound is a huge improvement over the original speakers. I gave 4 stars because the bass response isn’t as improved as I had hoped. Highs and mids are a great improvement.

By Saul on February 22, 2025 Verified purchase

Good Quality

Sounded good for factory replacements. kept the factory radio and upgraded speakers. I went with kckrs first and was disappointed. When I installed these I could actually hear the bass and the treble is super crispy.

By Daniel on September 29, 2025 Verified purchase

Very Happy

Running these directly off a head unit. They don't need a ton of power and they sound great. surprised by the lows and happy with the highs. Overall impressed with the sound at the price point.

By Travis on June 9, 2025 Verified purchase

Great price to performance!

I find these 6x9s to be just about perfect if your looking for a price to performance ratio. My bass was drowning out my subwoofer even with a alpine booster on my stock speakers. Great packaging from cerwin. I would buy again

By Logan on April 7, 2026 Verified purchase

Awesome speakers for an awesome price

I'm a big Cerwin Vega fan. When I was a teen I had a pair of stroker 15's that was awesome. I can't wait to get the XED963s installed in my 2020 Charger.
