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!

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

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.

NVX SDBSK2 Premium Stealth Black

Great product, Sonic Electronix is great. I've ordered a few things from time to time and have had no problems. I get the item quickly. I ordered this and was so pleased. I ordered another set. Works great.

crunch speakers

Install was very easy.Quality was very nice for the money.

Really good for the money

If you want to add a little thump to you car with out hurting the bank these are great. Easy to install

Not a great option if your going to throw real power at them.

Hooked a set of these up to my Rockville RXD-F30 micro amp, which is dyno tested @ 100 watts RMS x4 @ 4 ohms, so according to their specs, these should have handled it. NOPE. Installed per instructions, Tuned my gain on the amp with a multimeter as the sonic electronix youtube video shows, so it was tuned properly. Ran all new 100% pure copper 16 gauge speaker wire throughout the entire system, so it is a solid setup. Speakers lasted about 15 minutes at 3/4 volume, never turned my head unit up all the way, though I should have been able too, as no distortion via the multimeter was noted when testing prior to hooking up the speakers. I should have figured this would be the outcome from such a budget set of speakers, but what can I say, I was trying to be optimistic. Now I need to order another component set that can actually handle the power. Kinda sad, the rear speakers were a 10 year old set of Alpine 5.25's rated at like 55 watts RMS or something like that. I expected to blow them and replace them, but was curious how long they would last. They are both still working, a few months later, though one is slightly distorted. Just sayin crunch.....maybe put a realistic RMS rating......like 30-40 or something lol.

I will say, these probably work fantastic powered by a head unit, at 15-20 watts RMS. Or by a crunch amp, (over)rated at 150 watts RMSx4 (will likely be pushing 50 if they rate the same way...)

Anyway, the take away from this, is don't be cheap if your going to push real power. Should be obvious, but I fell for it. Shame on me.....

Running off a head unit, these are probably great. I will say they sounded alright for the few minutes they lasted.

GOOD STUFF

Good. Thanks. They fit great and sound wonderful. I like them a lot.

Great value. Not sure about durability.

Price was right. Great sound overall. One tweeter in first use already blown.

crunch speakers

price cant be beat. of course theyre not alpine or reference speakers but any aftermarket speakers are 100% improvement

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 for the money

Not bad at all. Better then I expected.... !!!
Good for the money and nice clean sound on my kicker 250.4 amp ...

Value is key

I replaced my wifes factory component system in her tahoe with this crunch component system. The Bass is decent for the price but the mid bass production its what would make me buy again and again.

Best sound for the price

If you are on a budget this is the way to go. Great sound and very durable material. This is the best bang for the buck

Great speakers for the price. Would make a great replacement speaker for stock. I have them in the rear of my 2012 civic. Highs are great, as far as bass im uncertain as my stock deck doesnt run a full signal to them. The speaker wire is extremely thin, but works. And as i remember there is like a 1.5 ft of speaker wire between the tweeter and mid.

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

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

Cheap for a reason

Cheap way to get some new speakers in your ride but don't sound much better than stock. Just dont think you can toss these in an have an amazing sound. Entry-level stuff right here.

crunch 2 way

Best value in a 6.5 component,great for rear door use. Sensitive and high quality over stock.

Great sounding components

I’ve used other brands before and this is the first set of crunch speakers I’ve owned and so far they are holding up to the abuse (loud music) I’ve already ordered another set for my other vehicle.

Crunch CS65C

I would highly recommend this product to everyone . Best sound I have had in 30 years.

Crunch cs65c

This is a good speakers set and for the money it's really good. I use them in a portable box and they sound really good and loud. I will say 5stars I'll buy more from "sonic electronic".

Awesome Sound and Value!

I'm totally blown away by the clear beautiful sounds from these inexpensive speakers, would recommend to everyone. Love my car radio Again! Thanks

Good value

Installed in 03' Mitsubishi lancer

Tweeter is larger, did not fit in a-piller pod. Required modification to the door panel. The hole in the door panel must be a good tight fit, or the tweeter will fall out. Tweeter mounting kit is non existing. In testing fitment the tweeter popped out of its trim and is now loose fitting and will not tighten.

Mid/woofer mounting required a custom plate to fit the Lancer door panel. Once all wired , sound is great and no complaints what soever. Cross over is nice and small. Tweeter and woofer wire from crossover is rather short though.

Best Punch for your Buck!!

This amp works wonders for the price!! I put it in my wife's trunk with a Kicker 12"from Wal-Mart and she loves it super cheap super easy super loud thx guys

By Nathan on November 24, 2016 Verified purchase

Great Item

I would recommend this item for anyone that is just wanting a little boost in their system, priced right with quick delivery.

good value

Good products I'm really happy with those speakers.I will buy them again.thanks you

great value

I purchased the speakers to replace existing speakers in a 95 Miata and they work great .

Very awesome

For the price, I was very skeptical, you always get what you pay for, right? Wrong, Young Padawan! These things surprised the hell out of me. Running them off my stock radio until my aftermarket one arrives, and these little suckers still rock. Great bang for the buck and even with stock radio crapola power, they will screech your ears with highs. Now, don’t expect them to keep up with some 600 dollar, break-banking, super magnet door weight, but for that price tag, I’m considering buying two more sets and working on a headliner fabrication for them. Seriously worth it.

Crunch CS65C

This is a great product, has awesome sound quality and very reasonable in price. We liked them so well that my husband had me order another pair for his truck. And the shipping was really fast. Definitely recommend these if you want good sounding speakers.

Great sound without breaking the bank

I wanted to upgrade my factory speakers since they were old and rattling. These crunch mids worked very well and the tweeters look great. Could not be happier. Would buy again.

Nice product

Love that I got it for discount with speaker purchase. Works like a champ!

By Craig on October 18, 2025 Verified purchase

Makes sense Works perfect

I put a square behind ea. door speaker and a square on the inside of each pod and it made a solid difference, especially for the pods. The music sounds better, no hint of an echo or slight vibration that I'd get before insulating with NVX SD. Pods/speaker boxes should really come insulated from the factory. Install some squares behind your speakers and you'll hear the difference.
