DS18 ZXI-354 with Speaker Installation Kit

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.

This product is very thick compared to cheap versions. Priced excellent. If you want to reduce any vibration or road sound, choose this!

Thick and heavy. I was suprised with the actual quality. For the price they’re great quality

Awesome roller!

I'm really happy that I bought this roller. I also have two other (smooth) rollers, but this one works much better. Its little "fingers" press the NVX sound mat really well and it allows it to be spread evenly over the entire surface including all these different curves and corners. The roller is very sturdy too. After 30 sq. ft. the roller started squeaking a little, but it still keeps working perfectly! I'm sure that the roller will help me to put all 60 sq ft of the sound mat and still will be fine. Great roller!! This item is highly recommended and even "a-tool-you-must-have!" for anyone who works with sound isolation of vehicles!

Way better than version 1.

I am an installer and could not disagree more with the other review. I actually had version 1 and got it the first time I ordered a bulk pack with Sonic years ago. This version is a big improvement due to the teeth and the handle. The teeth make it way easier to get a great stick to the vehicle body. The older one was wooden handle and this one is plastic, but the plastic is rugged and it is singular piece so it is really sturdy. The older one that connected the handle to the roller part broke at the joint and this one reminds me of a sturdy broom I have from Home Depot. Worth every penny paid or free!

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.
