Awesome set of tools

These trim tools came in handy and were a big help. Great value for these tools.

Very slick tools to efficiently slip wires/cables into car interiors

This kit was recommended by the Sonic Professional Installer staff to slip a wiring harness from the trunk beneath leather seat corner, beneath door entry panels into plastic wire channel, and on through the dash of a 96 Lincoln Town Car. I was dubious that it would be needed but found it protected the continuity of wire insulation, made the job easier, and was indispensable for removing the plastic fasteners holding the knee protection panels beneath the dash. Most home workshops do not have tools equal to the job that can prevent gouges and mars in these expensive interior panels. They are sturdy and well worth the price.

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!

Very pleased

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

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!

Nice product

Great price and it will replace my old ones that got broken somehow

Good product

Sticky and did hook well to the cars body . Got it for free with my speakers purchase. Sonic electronix for life

Sturdy tools

I used these very little yet but for what I have so far, they feel very durable and there is a tool for every need.

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.

Essential

Essential tools in one kit. Made my work a lot easier.

By csmt on December 19, 2020 Verified purchase

Great value

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

All plastic

This tool should be free with purchase. All plastic. It does feel strong and it does work but not worth the money.

By Donnie on June 8, 2021 Verified purchase

Good quality

I was actually impressed with the quality of the plastic not all too bendy and pretty diverse kit

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.

Perfect for tight spots

I used this to install true 50 mil sound deadening in the doors and along the floor of my f150. I installed it with this and the more traditional roller. This is perfect for inside the doors where bracing and cutouts don’t allow you to get great pressure on the material, the textured nubs give you much more focused pressure and allow you to get to stick and leave a small bit for air to escape when using a heat gun and following back up with the smooth rubber roller.

It also takes down kind of like a disposable razor giving you better access in some cases.

I used a cheap sound deadener from an online retailers house brand, the butyl rubber was not very tack and this got it to stay no problems I forgot to follow with the heat gun inside the door skins and this still kept everything secure.

Great handy product easy does it .

Great product , easy and handy to use , the roller is well crafted and helps out a lot . Well recommend happy with my purchase . The only concern I had was that I ordered it during the week before checkout it said I would be receiving my purchase on sat it took more than a week to receive it . Other than the shipping miscue I will purchase from sonic electronix .

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.

awesome product

product is a great deal I love it made installing the head unit a breeze

By Ian on December 25, 2017 Verified purchase

Insanely genius product

I've installed car audio for years and was always looking for the best way to improve the door panel and mounting locations. I've done everything from making wood brackets to sound deadening the whole door panel inside and out, even that doesn't compare to what these simple silicone baffles do. For a fraction of the price. I'm ordering more sizes now for the future.

Works great

When package arrived it was open inside the box, missing 2 of the 6 pieces. The tools I received worked, kit may have worked better had I had all tools.

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

Worth it

Definitely eliminates the headache of removing panels and clips. Recommend for and audio install

Works ok but handle is tiny must be made for tiny people. Plan on strapping on a bugger handle.

By steve on December 1, 2023 Verified purchase

Fair enough for what you pay, gets the job done.

These do exactly what you need them to do, although the pointed skinny one bends very easily. I would personally just recommend going with a screw if you are ONLY trying to get your stereo trim out, since that is what I did. Cannot speak for any other uses of this, but they do what you need.

By Garrett on August 22, 2022 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

By Big pat on June 13, 2021 Verified purchase

Easy Work

The plastic tools are easy to use even if a person has limited operation in use them before hand. The tools are very durable. Tools would be an added bonus to any self help repairs and improvements.

Getting To your Receiver

The tool kit(Belva BTK106) was good in keeping me from scratching and tearing my car's interior. I'm happy I decided to purchase it.

Restoring my van

Great product.big improvement on the sound of the speakers in my van

A must have for any audio/video installation. Weekend warrior or professional shop!!

These items are great for the removal of kick panels, door panels etc. I've gone through 5 different sets of these over the past 4 yrs and will continue to use the same brand. I would recommend not to leave them in direct sunlight or in 90° or greater heat prior to use. This might never come into play depending on where you live, but in Florida it's always an issue, even in our air-conditioned garage. The versatility of the different style tools makes for easier removal depending on where and what panel needs to be removed. I would recommend these tools for any installer, wether weekend warrior or professional shop.

By David on June 6, 2023 Verified purchase

who would have thought

I wasn't too sure about buying these but I am so glad I did. I want more but when I looked out of stock. I guess everyone wants them and should buy them.

Protecting them sonic gems

I'd venture to say if you have an older vehicle, especially an older pickup, we know all too well the havoc that moisture+time can wreak on all sorts of internal door components, despite good window seals. I just had a refresher course on that topic when replacing the side view mirror; decided since I had the panel off, why not do some cleaning and maintenance... pulled out some corroded butted MTX terminator 5.25, terminals, frame, all in sad sad shape. they were due for replacement, (passenger door driver suffered puncture wound beyond cosmetics)

To stay ahead of the elements and protect the fresh upgraded replacement speakers, I am using the 5.25 nix baffles in the doors of my '90 Jeep Comanche.

first impressions. the bolt pattern aligns great with stock speaker mounting, thumbs up.
the material feels like it will last many years. rubber baffle material also act like a gasket between the metal of the door and the driver. the back of the baffle leaves about an 1.5" gap between outer doorskin, where I placed the foam circle. it extends plenty far beyond the rear of a Kicker KSC5 driver, which is promising for protecting the rear assembly of the driver.
I treated the door with NVX 91mil thick damping material. one is treated, one is untreated. I will do a comparison of how the baffle performs in a damped door environment, Vs. undamped door environment. will report back soon

it should be noted that if the door panel doesn't allow for much space between driver mounting surface and inside of door panel, one may have to trim some of the material from the baffle mounting lip. test fit door panel before trimming the ring though!

if this^^ doesn't apply to your situation, the extra material acts to channel more sonic energy into the listening space, less lost to the voids of the back of your door panel.

By Dylan on September 16, 2025 Verified purchase

Impressive sound, especially for 5.25 inches!!!

Loud and clean vocals. Crisp clear highs. Enhanced the sound all the way around. Brings out sounds I never heard with the factory speakers. Powered by an Alpine F-300 and running off of a Pioneer head unit.

Had my factory speakers amplified by the Alpine F-300 already before installing the Infinity set. It was already loud and clear but now its on another level. Even louder and much more detailed. Night and day difference. Good sound for a good price!
