    Benefits of Sound Damping

    Sound damping material is key to reducing the rattles and shakes in your car. It effectively reduces the amount of road noise that is let in through the thin panels of your vehicle. It also lessens vibrations that are created by playing music through your speakers. It works by adding weight to the desired panel, which lowers the resonating frequency. You will notice 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.With the SDBP40, rattles and vibrations will be a thing of the past.

    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.

    1. Fantastic Product  star rating

      This is a fantastic product and the price is unbeatable! It is very dense for the thickness, conforms very easily (I recommend using a heat gun as you roll it for ease of install), very sticky and most of all it works! Installed in my 92 K1500 which was a complete rattle trap to say the least... The stereo would have everything in the truck flexing and rattling so bad I didnt even want to listen to it anymore... I applied to main problem areas (roof, inner door skins, rear wall of cab) and wow what a difference! Sounds so solid and very little exterior/road noise (and I have 3" exhaust and super 10 mufflers)... Will soon be re-installing the stereo equipment so I will update my review to let it be known the improvement there

    2. this product is better than any sound deading material out there  star rating

      Way more bang for the buck. You get way more than your money's worth. I can say I got more than I paid for. I used dynamat before and only did half of my trunk. I used NVX and did my whole trunk and had a lot left over.

      Just finished the trunk in my 07 police interceptor and the difference is unreal. Easy to use and much nicer than competitors. Will definitely buy more to finish all doors.

      Best bang for the buck just as good if not better than other more expensive brands and the price can't be beat.
