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.

By Dustin on March 22, 2018 Verified purchase

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.

By Andrew on September 15, 2020 Verified purchase

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 .

By Chris on June 26, 2017 Verified purchase

Great deadner

This NBC deadner is awesome!! Works great and added better sound quaility to my new speakers stopped all the little rattles in my doors and covered all four of my doors!! Great product!!!

Big bang for your duck !!

This stuff is heavy looks like what we use to hold in the little kick window on doors of the big trucks.

Trunk silence

This is good quality material. Does the job. Great value for the price I have more left over than expected

By Andrew on May 5, 2022 Verified purchase

Good stuff.

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

By Roger on March 12, 2022 Verified purchase

Love them

They are a lot better than I thought it would be putting massive amounts of wattage and they are keeping up so far and they sound great! I might buy another set of them

Kappa 693.9I 6X9 speakers

After reading the reviews, I decided to buy two 6 X 9s for my buick lesabre. I hooked them up to a 450-W amp and was blown away by their power and sustained clearity even at high volume. I do not use them as Boom-Boom. I actually listen to clasical music. These speaker are great. A little pricy, but well worth the investment. As soon as Sonic puts the 6.25 Kappas on sale I will be getting those from the front door panel and power them with a 200-W amp.
Very clear and clean sound from a stock head unit.

Best seaker

These speakers sounds amazing! Friend of mine never like stereo now he going to buy for his car!

Surprised

Purchased these for my wife as I rarely listen to music. I was amazed at the sound quality, I could hear parts on the music I didn't know existed. Am thinking about getting some for my truck now.

They sound great

I have them running off a 800.4 power series amp. Amazing sound. They are really loud and clear. Great mid bass. I would recommend to anyone looking for a great sounding 6x9 that can handle some power. And at the sale price, you can't beat em.

Nice 6x9s

I was looking to upgrade my 94 Camry from factory rear speakers to something nice without breaking the bank. The speakers sound great and have worked well for the past 6 months. They are a bit of a challenge to fit in the 94 Camry rear deck but with some cutting and modifications they now fit.

Infinity sound reproduction Kappable !

If you are looking for an incredible sound from your car speakers, don't look no further and go for these incredible quality engineered speakers !
Once again Infinity is on top!

Great Sound

I replaced the all the speakers in my 84 Camaro and they rock with the Sony CDX-GT700HD head unit I also purchased from Sonic Electonix. Great value and sound!

I can't go back

Single cab dodge with a Hifonics Zeus amp. I'm not even done dampening the doors and the sound is way better than i expected. So clean, crisp, and loud. At first I felt bad about spending so much on speakers until i spent a few hours enjoying them. Now i cannot go back to cheaper speakers. I wish they were cheaper but they are worth the bucks. Install has been challenging due to the huge magnet these have and the low mounting depth in my application. These pretty much require a quality amplifier to get the full experience. If you can afford these speakers and a good amplifier you will be pleased. I would run 4 pair of these for my home theater with some JBL GTI subs if my wife would let me spend the cash.

Great speakers.

These speakers sound great. I would recommend Infinity to anyone.

Excellent speakers

These kappa's are ridiculous. Super clear highs ,fantastic lows ,and believe me they are extraordinarily durable. I've installed a lot of different speakers for people ,and sure I've heard SLIGHTLY better sound quality but it wasn't worth two or three hundred dollars more that people payed for it. THIS truly is the best BANG for your buck!

LOUD and CLEAR!!!

I have always been a component set guy until I decided I need more mid bass....well I got both with these speakers clear and loud on all frequencies. I now have two sets of these and my focals...I plan on getting on more set of these...Only thing I wish it had is a swivel mounted tweeter.

For Brasilians!

Great addition, the sound is perfect and clean, and give up the bass with a button-3db. Same technology as the JBL GTO. Quality! A +

Great speakers, Great price

These speakers rock. I installed them on my boat and they light up the whole beach. I'm using a rockford amp with 50 watts per channel and they sound great. I cant wait to hook them to my kicker and hit em with more power. I would also like to mention that Sonic Electronix is the most amazing place to buy these as they were less than half the price others were asking. The best sound, The best price, and the best costumer service.

Great,great sound

I have installed these speakers in a 1992 Formula Firebird and they sound great! Although the factory specs initially indicated that the speakers would be too deep for the space behind the sails they fit fine. I received them in record time from Sonic Electronix and overall I am thrilled. Great speakers!

awesome

Clearest crystal sound, loud as hell, no distortion, plenty of bass, I swear by infinity car speakers.

EXCELLENT

WORKS GREAT, EASY INSTALL, SOUNDS AWESOME, DEFINETLY RECOMMEND THIS PRODUCT

Respect Infinity kappa! They are some serious speakers!

I have a set of the model before this Infinity Kappa 693.9I in 99 camry hooked to a two channel RMS 300w alpine amp....it sounded like I a sub in my trunk! So for my brother's birthday I decided to get this set of speakers (Infinity Kappa 693.9I) for him and he loved it! Great highs, mid, and low.

I hooked an sub for a few month and my car was shaking bass but decided I need my trunk space so I went back to cranking the decent bass I need from my two kappa. =D

Best 6x9's around!!!!

i would highly recommend these speakers for crisp clean loud speakers.. these 6x9 speakers are great for competition cars and non competition cars

good

they perform as expected, low lows and high highs with everything in between in my half-cubic foot custom ported boxes, covers are a disappointment being made of thin fabric

Great Bass and Overall Clarity From Factory Deck

These speakers provide much more than I expected from my 07 Accord factory head unit. Every aspect of the sound is infinitely better!!! I adamantly recommend these. Note that some trimming of the underside of the read deck speaker covers is desired, but not required. The -3db tweeter switch helps the purchaser dial in the desired sound - I have chosen to leave it off (normal volume). Also, the crossover \'dongle\' significantly simplifies connections to each speaker. No doubt about it I will be following up this purchase with the 6.5\" components for the front.

You cannot beat these !!!

Have them powered with just a Boss dbl din radio and these pump good!

Superb value

Bar none I would recommend these speakers to anyone. The best sounding pair of speakers I have owned and I've owned a lot of speakers. 2ohm gives it a great sound and keeps ur amp a lot cooler. Hands down would recommend these to anyone looking for superb sound at a decent price...

Great service

Bought a pair of Infinity speakers for my car, delivered before expected.

Great Speakers

Love the speakers, i did run into a small problem, the original Toyota factory speakers I replaced had much smaller magnets. The new Infinity Kappa's had a larger magnet and resulted in a tighter fit in my trunk. Other than that the speakers sound great!!

Great value

I highly recommend this product. The sound quality from them makes them well worth the money. I would buy the exact same ones again if I ever needed to. Just make sure you have the space for them. They are pretty wide on the sides.

he best one in the market

I only deal with Infinity

Greatness that comes in a box

These things are amazing. I have four of these in front and back of a 2007 Camry. Highs, mids, and lows are crisp as it gets and I'm only pushing 75 watts to each. Most people can't even handle them when I turn it up half way. I cant imagine how they sound with 110 watts. Cant wait to get the amp to push that.

A+

GREAT! Powerful, loud and clean sound!

(+1) Took Pioneers to to put these in and WOW what a difference.

Infinity 693.9i

Use an amp with at least 110 wpc rms to get the absolute most perfect performance out of these speakers. Very nice. For jazz, great.

Excellent but.....

Just installed a pair in my 07 Corolla S, and they sound excellent. Install was fast and easy, but the cool looking external crossover dongle looking thing will cause a rattle if you dont tie it down some kind of way.

Awesome 6X9!

Installed 4 of these in my 2012 Ram single cab truck with a kicker amp. These rock at every level. They are paired with a sub so im just using for mids and highs which they do an awesome job. Music is clear and crisp. I tried them without the sub in full range and they have nice bass too. I found that the button set at 0db sounds a lot better than the -3db setting. The -3db setting made my 4channel amp run hotter and they sound better at 0db.
Only one problem i had was that i had to use the spacer included in order to make them clear the window and that pushed them out to where the door panel was pushing up against the tweeter setting button on the speaker. The door panel pushed the tweeter button in the -3db position so i had to cut a very small hole on the door panel to clear the button out to the 0db setting. This 0db setting made a huge difference in sound and performance on my amp. Sonicelectronix had the best price and very fast shipping without having to pay shipping upgrades! Thanks for an awesome product!

Great product and price

These speakers sound great and have a great bass sound and in particular great high range. I don't need a sub woofer as these have plenty of thump for all music types.

AWESOME set of speakers

Great sound and looks awesome too. A little bit on the pricey side but it worth the money because you'll love it.

buy them cant go wrong

Great 6x9 loud I have to a 1200 watt soundstorm amp gain all the wat up if u want loud 6x9 get the infinity kappa 3way u wont need grill speakers u can hear me with my windows up clear!

Kappas

These 6x9's have great sound quality. I have capacitors in them, so not sure how they are on lows. They sound great w/ 2 -12's and the rest of my mid ranges and tweeters.

good product

Good all around speakers for the money. Took pioneers to to put these in and WOW what a difference. Use a good powerful amp with them though,they are power hungry

Best price on the web! Great product!

I was looking for a speakers to balance the MB Quarts that I have which are more "precise"... so I need something more with more bass. The Kappa's are perfect! Sounds great and for the price, can't beat it!

Infinity Kappa 693.9I

SOUND CLEAN AND CRISP SOUND BEST WHEN USED WITH SOME GOOD POWER BEHIND THEM AT LEAST 75 WATT RMS

They're Great!

Love these speakers. They sound great. Glad I purchased them.

great value

i bought these speakers 6 months ago and they are absolutely perfect! i would recommend them to anyone!

Crisp, Clean, Pure

The closest you can get to a concert hall sound. I do recommend these. I do suggest an amp for them. They sound great with a stock deck. But Amazing on an amp.

Great speakers

Definitely an improvement over stock and @ 2 ohms can be driven hard with little power so low noise.

Love these speakers

Purchased these for my 2011 dodge avenger front and rear (had to modify fitment for the front) and wow do these sound awesome, what an improvement and loud too. Powered with a hifonics glx60.4. Very happy with the speakers, don't cheap out, pay the little extra and get these and give them some power!

Excellent Speakers

The more I use them the better they sound. They can handle more power than I dare use.

Kappa

I have these running off a Fosgate Punch 400.1, being fed about a 100 watts a piece and these things sound AMAZING in a sedan. The tweeters and midrange are clear and bright (I like bright). The bass on these is good, however, don't expect it to replace a subwoofer by any means. The woofer will distort loudly if you try to push them too hard or on some of the bass heavy songs. Overall, the entire speaker and set up is GREAT!!

Great set of speaker

Highly recommend. I am pumping 175 watts throught them and they sound great. I would recommend them to anyone.

best value for the money especially on sale!

Great big speakers, I mean big in size barely fit my door panel, this is the only small complaint, other than that a great buy, speakers sounds amazing compare to the stock infinity sound system in my car, clear sound, definitely a stock amplifier does not push these beasts close to their potential. got them so cheap I could not ask for more, thanks Sonic Electronix your clearance sales rocks!!

Tom

These speakers sound great. They have held up well and I have had them cranked up quit often.

ok product

did't meet expectations but not a bad product had them hooked up to 4 ch amp

kappa 6x9s (693.9l)

These have got to be some of the best 6x9s on the market! They get very loud, the clarity is excellent. They put out good bass but i would definitely recommend subs for hitting the lows so your speakers last longer. No distortion even when I cut the volume up to 55! Had a pair running on a Rockford 300.4 prime and now have them on a rockford T600.4. Had them about 9 months and still no problems.

Just Do It!

Please if you are even questioning getting these speakers, JUST DO IT NOW!!!! With the prices you get from Sonic and the free shipping you have no excuse not to. They are crystal clear and hit any note from a screaming pitch to a mid-high bass note. I've been in the car audio gig for a little while now and let me tell you, as car speakers go the Kappa series is hands down the way to go. Plus the price is right. Only recommendation is you pick up a power amp to feed these bad boys. Do your Homework, find and amp, and crank your head unit till your ears bleed.

Gift for boyfriend

I bought the Infinity Kappa's for my boyfriend for his birthday. We finally installed them a couple weeks ago and they sound amazing. The speakers that were in his car before were pathetic and cut out all the time. With the Kappa's, we can hear every note and word so crisply. I am completely satisfied with my purchase and I know he loves them!

GREAT PRODUCT

I have these, with a set of 6.5 kappa perfect components on a kappa 4 amp. These speaker are clear, loud, and durable. I would highly recommend these to anyone. Note that these speakers are going to give you quality from all ranges. If you are looking for speakers that just scream go with the references.

KappA

The speakers sound awesome, it has some incredible bass response also the tweeter make crisp clear highs, but the thing that i love the most is the mid-bass and mid-range. definitely recommended, you'll be amazed.

one of the best speakers

Thank you again Infinity. I had a reference type home speaker from Infinity before and like it too much. The Infinity does not disappoint me again, really great bass and high level frequency it has. The 46 reviews from this product shows everything.

Love my Infinity Kappa 693.9I

I have these in my Chevy Trailblazer customize on the back panel. They sound really good. Also have the matching 6 1/2 63.9I. These speakers are WOW, they sound clear and can handle everything you throw at them. Definitely worth the money.

Amazing speakers!

These speakers are amazingly clear and can handle almost anything you throw at them. I've used them while being powered from the radio and from an external amp, either way they sound great. Definitely worth the money.

great price

They are by far the best speakers I have ever heard but I also bought the Infinity Kappa amp as well

Kappa

Great Speaker for your dollar.

Amazing Product

I would definitely recommend this product to anyone who likes crisp sound. I have these speakers in my back deck of my 2004 honda accord coupe, and it has some of the best high sound clarity out of the many speakers i have heard. I have heard some people complain that the Kappa's have too high a pitch and hurt their ears, but in the last 6 months with these speakers I have gotten nothing but compliments on this system. They were very easy to install and when coupled with the right amp, the sound is awesome. This product is worth every penny paid, and I would definitely buy these speakers again!

Major improvement

after upgrading to an aftermarket head-unit, my speakers couldn't keep up with the power being dished out by the HU. Upgraded to the Kappas, and now the HU doesn't give enough clean power to the speakers. They are so clean, have such a wide frequency, and such a high power handling level, that they beg to be played louder than possible right now... Just what I was looking for!

Perfect seller!

Great sounding product, perfect seller, I've done biz 3 times, I'll be back! 100% recommended.

Infinity Kappa 693.9I

I just got them from sonic and installed them. I knew infinity was known for good car speakers, but these and the Infinity Kappa 60.9cs together make my music sound 100 times better than any speakers i have ever owned!!!!! just buy them and the Infinity Kappa 60.9cs and you will be happy!!!! just buy them!!! and buy a really good amp (kappa 4 channel) they need power!!!!

No complaints at all.

These are fairly cheap and capable of some pretty fair sound when coupled to an appropriate amp. Install was simple enough as they bolted right into the factory position. I would recommend these to anyone wanting decent sound on a budget.

Impressive

I'm powering these from a Pioneer DEH P3001B head unit, and they sound great, but you can tell at moderate to high volume that the head unit is struggling to power them. Can't wait to hear what they sound like with an amp. They can really pump the bass, and highs and mids are stunning for a 6x9. Not to mention that the design is gorgeous. These are definitely the best speakers I've sampled (and perhaps the best speakers money can buy) for under $150. Highly recommended, though, as another reviewer mentioned, you'd best have the funds to purchase an amp along with them.

Awesome speaker

Awesome speaker sounds great a little pricy but if you can afford it this is the way to go

infinity speakers

These were in my sons car and now they r in my truck and love them. very good sound!!!!

kappa 6.9

Good speakers for the price. Crisp and durable and loud.

Great Seller

Speakers work awesome and really fast shipping and great product!

Great sound

I bought 2 pairs of 6x9 kappa (on sale) in my 2011 Caravan hook up with pioneer GM-9500F 4 ch amp. Sound quality is great and loud. Now I add a JL Audio 10w3v3-2 with JL Audio 500/1 amp, my ears can't handle the volume. This is a great sound system and I'll tell my friends to buy this.

Kappas sound great!

These 6 x 9s have crisp highs and great mid-bass thump. They should last for many years with responsible use. The midrange really brings out the vocals... I'm glad I got these instead of the 2- ways. Click "add to cart", you'll enjoy these for sure.

Great speakers for the money

I have had these speakers for about 4 months and they have never let me down. They sound best powered by an amp but just a head unit makes them pound real hard. For the price these are the best speakers.

Absolutely Beautiful !

I have these top mounted on my rear deck and to say they look elegant is an understatement. The build Quality is top shelf. With 110 watts steady power handling, 95 db with 1 watt of power, 30 to 30,000 hz frequency response, and the mid/tweeter aimed at you, these speakers dont miss much. They sound like a small sub is in the car, and the sound stage is very spacious and crystal clear. I have 180 watts per channel of clean power, and my ears run out way before these speakers do. I am simply impressed everytime I listen to my stereo. If you demand crystal clear and precise music, these are a real bargain.

Speakers blew within 6 months

Initially, great sound. Installed them on my motorcycle. Both speakers blew after 6 months, didn't overdrive speakers.

They Slam!

I love these speakers i have them hooked up to my JVC headunit and they slam. Best 6x9's I have ever had in my car.

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.

By Martin on May 17, 2024 Verified purchase

awesome 6x9s

i ran these on 100w 150w and then 200w rms on various amps. they always kept on going. i pulled after 2 years and sold them. not sure how the new model is but this model kicked butt

By casey on February 28, 2016 Verified purchase

Thick and shiny

This stuff is heavy duty. I have no doubt this stuff is going to help on my doors. I love the shiny top, even though you can't see it once installed it looks good coming outta the box. Would def recommend this product along with any other NVX product. Have been using NVX for over 5 years and their products have never let me down

By Johnny on June 3, 2026 Verified purchase

Like concrete

Nvx continues to deliver. This stuff worked great. The price is phenomenal and my doors turned out great and way better sound quality with this sound deadening added
