Customer Ratings & Reviews

A lot of materual

Ordered this for my F Super Cab. I just wanted some material to apply to the inside of the door skins. It is a lot more material than I needed. Ford already has a small amount of sound dampening material. It did quiet the interior as expected. Great product. Came with no instructions. I just used some alcohol to clean the surface first.

love it!!!

Love this product. Great price and easy to work with.

Great!

put on my trunk to stop rattles. worked great, doesnt sound like a tin can from outside. thick stuff definitely a good deal. as good, if not better, as the bigger sound deadener brands but at a lower price. i highly recomend

Impressive product

This is a very stout, impressive product. It feels thicker than the famous competition and there is no smell to it. The sheets you get are sort of a long/narrow size, so they are great for running vertically up the doors and on the outer door skin. You'll definitely want a source of heat when working with these and really, there isn't a better value for the kind of product you are getting here.

NVX 12ft.

This is great material for a great price. Ive bought multiple nvx dampening products and have been pleased with everyone. This this easily applied with a nix roller and contains the perfect amount plus some to use on your doors.

Seems fine

Used on rear door skins. No smell, easy to manipulate.

Great for Rattles

Installed this stuff in my front doors and enough for the speaker area in the rear doors. It only slightly reduced the road noise in my car, but tightened up the bass and reduce rattles by a huge degree. This stuff is easy to install and can often be bought on sale.

Good product

Easy to work with and in my opinion it performs better than dynamat!

Decent Dampening

I have had this for almost three months on my trunk lid and it has made a big difference. The rattling is not as bad as it used to be and it made a difference inside the car.

DON'T buy this if you live in arizona because the heat is too much for it.

NVX SDDK12

Excellent sound deadener for the money, very thick, no smell once applied, super tacky and sticks even to dirty surfaces. Applied in my doors it made a big difference inside the car, applied in the trunk the bass sounds much better inside but it didn't stop my trunk from flexing and sounding like it's about to explode. All in all excellent product and would definitely recommend!

Fantastic kit

This kit is almost half the cost of competitors and works just as good or better.

easy

As good if not better than others, and I saved $$$. Easy to use. Easier to press to surfaces than the stinger.

Hands Down

Hands down!!! this is good stuff for anyone, who would like to enjoy maximum output and clarity. NVX greatly enhances the timbre and the acoustic of your audio speakers,you cannot wrong with this

NVX Sound Dampening Material

This was very easy to work with. It seems to be as good as any of the more well know and more expensive brands. Sound dampening at least the doors is necessary to seriously improve the quality of sound in your vehicle.

Best way to improve your system's sound

I was desperate to obtain a warmer, natural sound in the Rav4 I had just bought and did not want to lose any storage room. I had better speakers and small woofers installed in the rear speaker compartments but was still left with a tinny sound. Advised by the installers of the improvement benefits of this sound dampener, I had it installed and then came back for more installation in the rear doors and rear floor (I had the front doors and front floor fitted initially). I am very pleased with the improvement and it is definitely worth the investment.

Awesome Stuff

I installed four 6x9 speakers in my car recently and noticed that the doors and trunk were rattling. I was recommended this sound damping for my car. I found it very easy to install and it made a huge difference. I noticed a huge change from not only on the inside but on the outside of my car. I would recommend using this stuff if you have aftermarket speakers in your car. GREAT BUY!

Best Sound Deadener on Market!!

I had bought the NVX 12 sq. ft. sound deadener and WOW!!! this stuff works better than dynamat, fat mat, second skin, you name it, it is the best on the market, with the best price on Sonic electronix!!!! It is way thicker than its competition and simple to install. It completely deadens the sound in my doors! I hope to purchase more for the cab of my truck soon because it makes my speakers sound phenomenal!!!
I recommend this to all my friends!!
Thank you Sonic!!

Major Improvement

I ordered the pack so I could take care of a few flex and crackle issues I had on my roof, I applied the material in about 100 degree heat and it stuck and stayed easily. I used the nvx roller to adhere it and it worked nicely. The difference was night and day, it's tighter, cleaner and harder hitting. I did 2 layers above the subs and 2 layers above front seats in my ext cab pickup. Im running 2 15s on 3000rms so you know if it worked for me, it will work for you

great value

It's great for sound damping i recommend this product for sound deading in any application

Good

This sound dampening is great. thick and does the job. Has been on less than a year so the long run I dont know yet but so far great product.

Great product

Very easy to work with and gets the job done. My rear deck and trunk lid stopped rattling and now my headliner started. Highly rcommended best bang for the buck

Good stuff easy to apply does the job

After an accident i decided to treat 2 doors with this product. The other 2 doors use the Raamatt product which is more expensive. Application and overall sound damping is very very close. Next vehicle I will likely do the entire job with NVX. It is amazing how far this stuff has come since the original tar no stick heat gun application stinky dynamat product back in the 1990's.

Very Thick

This kit wont take your stock stereo and turn it in to a pavement shaker but it will help kill rattles and really helps clean up the sound. Its thick and very sticky so installation could be done by hand (I just used fist pressure) to work it on to the panels and make sure they are clean! Its somewhat easy to contour to corners and edges once cut in to smaller pieces and best of all, no smell!

Overall, my road noise was still there (pretty sure you need to deaden your entire car for that be noticeable) but I did find my music with a lot of mid, such as metal, sounded MUCH better in my standard coax alpines.

Awesome! Better than Dynamat!

For one this stuff is thicker. And half the price of Dynamat. I used the bulk kit in my car and loved it. Made a huge difference with road noise and unwanted rattles. I would highly recommend this to anyone!

NVX SDDK12

First sound deadener I've ever bought, worked great, easy to work with, helped with road noise and really brought the bass out in the front door speakers of my Cavalier!

Magnificent!

Don't waste your money on daynamat you can get the same quality at half the price with nvx. Definitely recommend this.

great value.

I like this sound deadner, before I would use peel and seal in my doors but got fed up with the thiner material so I bought this. I have used it in different cars, family and friends and my own and I like how easy it is too cut, and apply. Its tacky but not tacky enough that if you accidently stick it in the wrong spot you cant remove it. I also use the nvx roller which makes it allot easier to apply then just by hand. Iv had mine installed in my doors and trunk for over two years in the northern cali weather and still running strong without that nasty odor people think deadner has. Over all i would reccomend it to anyone looking to improve their midbass and stop those trunk rattle vibrations at a good cost.

Well Made & Good Value for the Price!

There's several manufacturers to choose from when it comes to dampening material these days. I have a hard time believing any specific brand is better than another, outside of knowing I want something that is on the thicker end AND with aluminum siding. I found there with NVX's product and it seems to offer more material for the price. I installed on the rear quarter panel of an SUV and it does work well! Thanks!

By Anonymous on June 27, 2019 Verified purchase

Perfect!

Easy to cut and install! Sticks and molds well everywhere I have used it! It really works!! Thanks!!

Thick! Great product

I installed first on my rear wall, in my truck. INSTANTLY noticed a sound difference after installed. Truck sound was tighter and road noise was cut down too. Very impressed.

Correct install kills the rattles

Enough product to do my whole car. Rattle problem solved.

The only choice

I've been using this stuff for years. Extremely good adhesive and thicker than competitors. I won't even consider another brand.

Best Price at 90Mil Thickness

I shopped all over for good prices on decently thick, quality deadener, and found this to fit the bill. I was not disappointed by the quality of the product, and the results were as expected. Just make sure the material is warm before applied, or it doesn't form as nicely.

Amazing!

These are excellent quality sound damping panels. Easy to cut and apply. I did not use much on my door panels. Only where cables could possibly rattle against the frame and applied some on the frame behind the speaker. What a difference It made with sound level and bass. My speakers sound loud and clear.

By Marco on June 5, 2022 Verified purchase

great

Like the other NVX products its a great value and works well. Sticks great and doesn't smell like some other products I have used in the past.

By James on March 7, 2018 Verified purchase

Excellent

If you're on the fence about this stuff vs dynamat look no further , do yourself a favor and get NVX , every bit as good as the other with a better price point .

Good stuff.

Easy to install. Not thin like some of the other products I have used. Very good price for the product.

The brightest highs you've heard

These are monsters. The midbass/bass from them when driven with the proper power is phenominal, very deep and clear. Don't even think of getting this set unless you plan to feed it 100wrms or more to take full advantage of it's capabilities. The build quality is great, and the spring loaded terminals on the midbass drivers are handy.
The crossovers, like everyone said, are gorgeous as well. They have dual inputs for tweeter and mids, so that means you can bi-amp them!! (and I recommend it!) That gives you separate controls of your highs and lows while tuning, and you'll need it because..
Let's talk about these tweeters. They are going to be love it or hate it for most. If you want the highest and brightest highs you've heard, these are the speakers for you. The tweeters are harsh to a fault, and without a way to calm them down (even with the 0dB bar in the crossover) they hurt. That being said, they're also extremely accurate and through the full spectrum of 50hz on up you won't miss a note. You'll want a source unit and music recordings of the highest quality to really enjoy the full package.
Take some measurements and be ready for just how deep the mids are on these, and the tweeter size isn't tiny either. They're going to need a bit of room to fit properly.
The only, only thing I would fault them for is that without the proper measures to tame the tweeters they may be overwhelming to some. A -3dB bar in the crossover design might've helped if they had built them that way, but that's neither here nor there.

great value

sound rich and clear ,nice mid bass. handle the power as shoud be! large crossovers to install ! :)

Great Component Set

I have purchased a few different component sets on recommendations from others and was never truly satisfied. I have tried Infinity Kappa, Kappa Perfect, Image Dynamics CTX-6.5, and an entry level Kenwood set. They were all good in their own ways but I knew I wanted something more. When I looked around for reviews on these, the users always seemed impressed but others gave Kicker no credit.

After finally getting these in (yes, my door holes needed to be widened and custom spacers were built at a local shop) they are my favorite set and I don't feel like I can ask for any more. For once, I have some tight bass in the front doors and the tweeters are clear without any harshness. I am running them off the front channels of an older fosgate 4 channel with about 90w rms and they will get plenty loud for me with no distortion. I have the tweeters set on 0 db and the front crossed at 40hz.

With rumors that Kicker was not so great anymore and that they wouldn't have great Sound Quality I was worried about the lack of clarity from the mids and a possibly harshness from the non-silk tweeter. After using these speakers for about 6 months those doubts have been put to rest and I would recommend Kicker and this set to anyone!

Beautiful

My background: Rouge Car Audio Installer, I've installed 5 complete systems as well as many other headunits and speakers. Always for friends and I always get to play with their systems. I love my Kicker sub and ZX amp. Whether good practice or not, I specifically purchased the Kicker ZX650.4 amp because it matched visually with my ZX750.1 sub amp. But I had no reservations about going to another brand for my component sets, I want the best sound. I've been shopping and researching for about 6 months. I didn't really consider the Kicker speakers at their typical $550 asking price even online, but one day SonicElectronix had these on sale. I then used the "Make An Offer" button to get em for a good price per pair. I bought 2 pairs.

My Set-Up:
Headunit: Pioneer DEH-5100
Sub: Kicker 12" L7 DVC wired to 2 ohm
Amp (Sub): Kicker 10ZX750.1 - 750W @ 2 ohm
Amp (Speakers): Kicker 11ZX650.4 - 120W @ 4 ohm (160W @ 2 ohm)
Speakers: THESE!
All Kicker power wires, speaker wires, RCAs. (They make some of the best cables)

Specifics:
Tweeter: At slightly less than 2 in, mounting can take a little thinking, but it's worth it! These Teteron dome tweeters are by far the best I've ever heard. Teteron - A synthetic material that is specifically designed to be lightweight and extreamley stiff. This allows the tweeters to sound precise at every volume level with no distortion or "ringing". A metal dome tweeter inherently wants to resonate similar to a bell, causing an inaccurate reproduction of sound. Compared to the silk dome tweeters I've heard, the Kicker tweets are much more pronounced. The tweeters are passivley crossed over at 2.8kHz which is lower than most systems I've looked at, but allows the larger tweeter to play lower frequencies. I've noticed that this lower cross point helps with vocals the most. Most speaker crossovers are crossed about 4kHz, which forces vocals through both the tweeter and the woofer. Lyrics come out so clear that everyone I show off to instantly comments on how easily they can hear the singer. THE TWEETER IS WHAT SEPARATES THESE SPEKAERS FROM THE OTHER SETS.
Tweeter performance: 5/5

Crossovers: One word, HUGE! They are not going to install in a car door and under the dash may wasn't posssible for me. The crossovers look outstanding and I decided to mount on my back seat to show off when I open my trunk. No reason to hide these. They have nice options of tweeter levels but I found the lowest, +0, to be plenty. I am going to bi-amp these speakers very soon. Passive crossovers are the worst option for good sound, you can find a ton of reading about it online.

Woofers: They can take tons of power, I have the high passed at 50Hz and they can take a beating. From the gnarley bass kicks of electronic music, to a Sublime bassline, these can handle it all without any distortion. But that isn't to say these woofers are any better than a similarly priced/ power rated set. From all the speakers I've heard, these fall right into their price bracket, nothing mind blowing, but well worth it. DO NOT buy this set for the woofers, although great, the tweeters are the star of the show.

Overall: Great buy, no regrets and happy as can be! PLEASE BUY THESE SPEAKERS! Size of woofer and tweeter make install tricky for sure.

nice sounding

Very nice sounding speaker, but also very quite speakers,
I'm running 75Wrms in each and they are far to quite for my liking, In my opinion they need 100-125wrms ea to make them come even close to keeping with the Kicker sub's in volume
Over all they are a very clean and nice sounding speaker

KICKER QS65.2

Great pair of speakers!! Just looking at the magnet alone n the woofer cone you can tell they are quality speakers. The sound is crisp. All highs and mids are sweet to the ear. To really appreciate them you must have a quality amp so please if you spend money on a pair of these do it some justice and purchase a quality amp if not then you are wasting your time. The only issue is that they are not made to fit every vehicle. I have an 03 Tacoma and had to do some alterations to make them fit both on the tweeter and woofer but it was well worth it. If you want quality sound then please purchase these speakers as you will not be dissapointed! THEY ROCK !!!

Simply Beautiful

well, before i even put these into my car I was stunned by how well built these are. The mid bass drivers are heavy and sturdy, the cross overs are gorgeous. I changed my install idea when I saw them so that they would be exposed and shown off! ;) but it was when I got everything hooked up running off my new Vibe Litebox4 amp that I was really blown away. loud, clear, detailed... the soundstage is near perfection and you can hear every little tiny bit of detail in the song. simply an amazing pair of speakers. A MUST buy.

Crisp sound quality

These speakers sound amazing! (Iv got them running of a vibe litebox 4) When I put the top down they still are able to completely surround you with every note in the song. They have good lows but a sub is needed if you like true bass. My only drawback with them is they are alittle quiet but it's a small set back for their peerless quality.

Excellent products at the best prices.

Better and thicker than Dynamat

It’s a no-brainer; this brand of sound deadening is the best for what you pay for. There are no drawbacks for this cheaper option.
