Customer Ratings & Reviews

Wife's Honda Crv

I ordered these speakers for her CRV was recommended by West the sales rep. Nvx NSP525 two sets they sound great. Ready to the order the 61/2 for my car. I recommended this product and the reps are nice and know.

Great product

These speakers look great and are very easy to install. Sound great too

Great Backfill

I purchased these to use as backfill in my NVX system and I am pleased to report that they have met my expectations to a T. They are plenty clear, and handle the power I am throwing at them very well. Like most speakers of this size and design they are limited by how much bass they can produce, but for rear fill in a system they are perfect. My kids say this is a huge improvement over the Bose speakers they replaced.

Nvx speakers

I recommend the nvx speakers worth every penny can't go wrong

perfect for Harley bagger upgrades

I have 4 of these running off my JVC head unit and they are plenty loud for the highway plus my loud exhaust on the bike overall love them and will be using them on all my bikes from now on

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!

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.

NVX NSP525

Low power handling but great clarity for a budget-friendly price.

By Casey on March 22, 2020 Verified purchase

Good speaker for the money.

Looks like a speaker costing a lot more . Sounds great, although not like a speaker costing a lot more.

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 deal

Originally bought these to put in my vehicle but ended up using them as my center channel in my surround sound system and I'm not disappointed they sound great

Review Speakers NVX=NSP525

A great speaker for the price. All around good, could make a little more base.

By Darrel on May 30, 2016 Verified purchase

Great bang for the buck

So far, NVX hasn't let me down with anything I've tried. While these speakers certainly aren't "audiophile" quality, they are without a doubt better than anything I've ever heard in the same price range. I have them running off of an average power H/U with no amp and they still supply plenty of clear volume.

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.

By Joseph on February 2, 2020 Verified purchase

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

Perfect fit and Great Sound

Bought a pair for a 2011 Ford transit, they fitted perfectly like they were OEM. The sound was great with the stock stereo. Doesn't come with extra wire to wire up , so I had to buy my own.

By Yiron on August 16, 2020 Verified purchase

Nice little speaker, good value

Seems to be well made, sounds decent. Highs are clear, but not overly bright or hissy. Bass is respectable for its size. I'm pleased. I'm rating it 5 stars for value.

Does the Job

By NICK on December 3, 2022 Verified purchase

easy fit

sound really good for the cost. very nice speakers. would expect them to cost more

Excellent bang for the buck!!

These speakers far exceeded my expectations based on the cost. They are very well made and sound great, probably as well or better than the much more expensive speakers I have in my other car.

Very surprising

I have been something of an audiophile most of my life, heard and built alot of really good systems. These speakers are a very good deal for the money. Sound as good as most speakers costing $100 plus a pair. I was totally surprised when I threw them in an old truck just for some sound. 5.25's in the doors, 5X7's in back. 17 watt RMS head unit power only, no amp. Not alot of bass, but they aren't meant for bass. Really nice clear mids and highs, with a bit of bass thrown in. I would HIGHLY recommend these speakers to anyone looking to upgrade a factory system, or even to use as fill ins on a higher powered system. Can't go wrong with these for the money.

Great Upgrade for my Dodge Caravan

I am so impressed with these 5.25 front speakers, especially for the price. I had to replace my front speakers and purchased a pair of NVX as replacements. They look and sound so much better than I expected! So good, in fact, Im going to purchase a pair of 6x9's for the rear. Highly recommend Sonic Electronix and these NVX speakers.

By Daniel on August 31, 2023 Verified purchase

so far so good

I have 2 sets of these in my 1991 Cherokee Laredo 4.0 2 door and they sound amazing, I'm glad I chose to go with NVX, in my next build I think I'm going with nothing but NVX products.

Great product

Ordered theses for my husband's truck to help make his radio sound better. They did the job beautifully, and they came in a about 3 days after ordering, I have parts from other places I'm still waiting over a week later they get a A+ for product and delivery.

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

Great speakers, but the 6x8 that should have gone in would have been better

I did purchase these on Amazon but Sonic was the vendor (Sonic showed out of stock but not on Amazon). I used the fit guide from Sonic, I should have went with the 6x8 that another competitors fit guide said was correct (2008 Grand Marquis.) but the fit guide at work said either could be correct.) So I used the adapter plates (insert pain in the backside) self taping screws and they are in solid and sound good, hopefully during my next days off I'll have a chance to swap out the head unit and add the 4 channel and mono block amps along with the sub woofer. looking forward to hearing them with other than a cheap ford head unit. BTW the head unit, 4 channel amp kit, 4 channel amp, RCAs along with the mono block amp, sub and box all came from Sonic, all NVX but the head unit and 4 channel (Cerwin Vega), great service guys and I'm certain once I get the rest in I'll be grinning ear to ear!

Thanks again Sonic, keep in mind I work for an electronics retailer that sells car audio, it was my function there for years, I sell different product for them now. I
