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!

Great sound and great price.

good value

Good sound for the money.

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.

Disappointed in Rockford Fosgate Primes

I am sorry that I bought these speakers for my car. I bought them because of the size - fit was important. But I should have been more careful.
These speakers have no middle or base tones. It is all shrill highs, to the point where they actually hurt me when I listen at times. Ouch!
Maybe its the materials (Mylar cones?), or maybe the size (too small), or maybe I'm asking too much for the money (less than $100.00/pair)? But the OEM are almost better. And that is not saying very much.

Great value

I installed these on each rear door of my 2005 Silverado. Could really hear a difference in sound quality.

Best bang for your buck!

I have 4 sets of these in my Subaru STI, one in every door. All 4 are powered by a Rockford Fosgate Prime R300-4. I am beyond happy with the clarity of the speakers. The highs are incredible. It sounds like the hi-hats are in the back seat. The mids are smooth and not distorted in the slightest. The lows leave something to be desired tho. Lows tend to distort at higher volume. I set my system up so that these components do not need to handle the lows, my sub does that.

All in all, I would recommend these to the person who's looking for clarity in their system. If your a huge hip-hop fan, these probably aren't the best option for you.

Great sound great price

I installed a JVC receiver, the components front and rear, and a 10" Fosgate sub with amp and cap...the highs, mids, and lows are incredible. You don't realize the acoustics you're missing until you do something such as this (chimes in background, etc).

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.

GREAT SPEAKERS FOR YOUR MONEY

love these speakers, they sound very clear. I'm running a pair in rear doors and got the r1652s in front with JVC kw-avx730 head unit no separate amp

Love them...but

I love the sound and quality of these speakers but when it came to installing them, the mounting bracket and holes are too small for the opening in the door, so I had to make modifications using the old speakers, just made things seem mickey mouse but wouldn't have worked without it...but still love the sound!

Great speakers at exceptional price

These speakers are crystal clear and provide enough sound to over come the sound from my loud exhaust. Def recommended to all.

small speakers big sound

Very happy with these, I thought these little speakers would be weak. well i was wrong they are loud and clear.

Great value

For the money you cannot beat this. I have these in my truck and they're loud.

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!!!

This speakers sound good for the price, i would recommend them to anybody looking for some cheap good speakers.

RF PRIME

Do yourself a favor and get these speakers. You can't beat the sound for the price. If i had more space in my car i would get another pair.

Does the job

Ordered this to install in a friend's car. Still sounds great after all this time.

R.F. Speakers

NVX SDBSK2 Premium Stealth Black

Perfect fit an very fast shipping.Good list to choose from to fit my car.

Fosgate Prime is better than you'd expect for the money

I'd highly recommend these for anyone running straight off an aftermarket head unit or as factory replacements on a stock unit. I have an OLD Alpine head unit that's 60x4 and it pushes these just fine. Very crisp, clean tweeters that are natural sounding and not too "tinny". The midbass and vocals are good...not spectacular, but good. That may be because I don't have the adjustments on my head unit for midrange though...only bass and treble. About the only drawback that I can see is that the tweeter mounting is somewhat bulky and really shows if you use surface mounting. In a flush mount situation they would look really good. I have an FI BTL 18 in a 5.5 cubic foot box tuned to 36 Hz on 1800 watts rms and they keep up just fine using just the head unit to push them. Great value for the cash.

Nissan Titan

The speakers are great. The ones I ordered were too small, but I got them to fit and they sound fantastic.

Nice!

Nice speakers all the way round. Just got em hooked up 2days ago to the head unite (no amp on them). I have a Jensen VM9214 7" touch that I also got from sonic electronics. Lil distortion when speakers are up real loud but nothing serious. Highly recomend these speakers.

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

Awesome Spekars

These Speakers are LOUD, CLEAN and CLEAR! That's all I have to say! I totally recommend!

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

Great replacement front speaker

I got these as a replacement for the front speakers on my 2002 Pontiac Grand prix, Non-Bose. I used the adapter wire set so it was a plug and play affair. I used the factory tweeter wiring harness and cut a hole in the factory speaker grille to mount the tweeters. Now the front staging is brilliant. Much better than the factory location. Total install time was around 3 hours. Buy a bunch of door panel clips because now is a great time to change them, Ask me how I found out. Now it is time to add an amp and sub. Rock On!!

very nice!

these things get the job done. they are greatly balanced, and they also get loud without any distortion. not much bass but that's because its a 5 inch sub. but overall great speakers. the built in crossover is amazing. helps to make the car look stock. i will purchase rockford next time :)

Good speaker

Good replacement speaker.

Not the greatest

Well i bought these speakers. They were not my happiest purchase. In general I just found them to sound like garbage and they are not very loud. But I will say this I ran them at about 3 times their rated power, and they lasted for a good three months. And they actually sounded pretty good. So pretty much I feel you can get better with the money.

Does the Job

Good price, fast shipping, works good. Greatly improved bass while also making the vehicle quieter.
