The Hidden Difference

If you want to make sure the difference in your sound is heard, not seen, then you've found the right stuff. The new NVX SDB line of sound deadening makes it easier to get that stealth look, instead of having silver backing peeking through your grilles. You get the same quality, sound-improving dampening NVX has always offered, but now you've got something that seamlessly blends into the rest of your install.

Benefits of Sound Damping

Sound dampening material is key to reducing the rattles and shakes in your car. It reduces the amount of road noise coming through the thin panels of your vehicle, and does so effectively. It also lessens vibrations created by playing music through your speakers. By adding weight to the panel where it's installed, it lowers the resonating frequency. By adding this material to your car, your sound system will likely get noticeably louder. If you have subwoofers, this is the perfect kit for your vehicle.

Thicker Than the Competition

NVX is one of the world's leading manufacturers of sound dampening material, and is up to 30% thicker than the other brands. Don't pay ridiculous amounts of money to kill those rattles when you can get everything you need from NVX for a fraction of the price. With the SDBVK4 dampening material, you'll get even higher quality sound from your system and a drastic reduction of road noise. With 4 square feet of material, you'll have enough to cover all of those problem areas that have bothered you for so long!

How to Install Sound Damping Properly

Sound damping can be a very beneficial accessory to reduce noise and vibration. To take full advantage of this soundproofing, read these instructions carefully and follow them till the end. It’s important to familiarize yourself with all the details to install the sound damping correctly. Incorrect installation will result in less than desirable results.

Step #1

The first step is to decide which location in your car you want to insulate. These locations include the floorboards, roof, door panels, trunk or firewall. We recommend soundproofing all metal surfaces for maximum sound deadening performance. Next, refer to your vehicle’s service manual for information on how to dismantle the trimming panels. Be careful when removing the panels to avoid breaking the fixing clips.

Step #2

Once the trimming is dismantled, remove the remainder of the factory insulation if it is damaged. If it is still intact, there is no need to permanently remove it. Next, you need to properly clean, dry and degrease the prospective surface. Sound deadening won't adhere properly if applied to a wet or dirty surface. Use a metal surface cleaner or degreaser along with a dry, clean rag. Make sure to use gloves and apply the degreaser in a well-ventilated space.

Step #3

For this step, measure the prospective surface you are going to treat. To make things easier, make a template of the appropriate size on a large sheet of paper and then transfer it to the damping material. That will make it easier to install it more accurately and avoid wasting material. Use a utility knife to cut the desired shape and size. Be careful and use gloves to protect your hands.

Step #4

Place a sheet of sound damping to the surface without removing the protective film. If it covers the surface properly, you are ready to install it. Gradually remove the protective paper film as you apply it to the surface for better adhesion. Once on the surface, press it down firmly until it is set in place. Flatten it with your hands to avoid unnecessary air bubbles. Use a rolling tool like the NVX SDRLR1 to press the mat down to the metal surface. Go across the entire surface with the roller to ensure that the sheet is installed properly.

Step #5

Once all sound deadening is in place, simply reinstall all trim pieces and carpet back to its original placement. Now you are ready to enjoy higher sound quality with fewer vibrations.

NVX did it again!

Got my 1st NVX Sound Deadening in 2012. Loved it! In 2018 I am just as pleased! Another easy to use, durable and quality product from NVX!! NVX has not disappointed me yet! Thanks Sonic!

Just what I needed

The nvm sound dampener impressed me, it makes a world of difference. The rear deck in Honda's pretty lightweight and the trunk latch isn't exactly secured tightly. There was a mess of rattling in the back and I slapped some NVX dampener on and it cleared most of it (if I went all out it would've been tits) I'd be beatin up the block and not looking like a fool sounding like the rear of my car was falling apart. Only thing in the trunk it did lose output outside the car. Not really a con unless you focus on how load it is outside, not where its supposed to be

NVX SDBVK4 Premium Stealth Black

So far so good, works wells, less rattling in my trunk and easy to cut and apply, I recommend using the roller.

Great Quality and Good Value!

This kit was of great quality and did a great job of dampening the miscellaneous problem areas in my car that had rattle from my car system. I love that the color is black so it is not as obvious to the eye like other brands with glaring foile material on the non-stick side. I definitely recommend this kit to people who want good quality sound dampening on a budget.
