Soundproof car mats often go by the name “deadening mats,” and their aim is to reduce the amount of noise you hear in your car. Installing a deadening mat will stop you from feeling like an ant stuck in a hair dryer as the wind filters under your doors; it will also prevent the rattling vibrations inside the car itself. 

Background noise can be super distracting. Soundproofing your vehicle will turn your aggravating journey into a smooth ride. It works by creating a sound-canceling barrier through a layer of breathable material. Most materials also act as insulators to keep the equipment cool in the summer and warm in the winter.

If you want to find the best deadening mat for your vehicle, then look no further! We have found the 5 best soundproofing mats so you can buy them with confidence. Not only that, but we have laid out all the information we used to find the right mats, so you can take that knowledge and search independently if you’d rather.

5 Best Soundproof Car Mats

Each of these mats would be an excellent choice for your vehicle, but depending on your specific needs, you may be more swayed by one or the other. Our reviews will look at how easy the mat is to install, the quality of the product, how versatile it is, and how protective it is.


KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Kilmat is a super popular brand, and it is easy to see why! The materials used are both thick and lightweight, creating a chameleon-like deadening mat, and each packet comes with an easy to follow guide to install their product. Kilmat’s goal is to be affordable and easy, and we can confirm that they are both!


Kilmat’s soundproofing material weighs 0.5 pounds per square foot. This means it can be used by any vehicle without slowing down your car’s speed. 

The lightweight material also means it can go anywhere in your car, and you don’t have to worry about certain aspects being too weak to hold the additional weight.

The list of where the mat can go is extensive:

  • Hood
  • Roof
  • Rear Deck
  • Rear Door
  • License Plate
  • Trunk
  • Rear Wheel Wells
  • Rear Floor Panel
  • Front Floor Panel
  • Doors
  • Fire wall
  • Front Wheel Wells

Most soundproofing mats cannot be placed in the walls or along the license plate, as their weight will ruin the aerodynamic positioning. Kilmat, however, is one of few which can be placed here and will still act effectively.

Easy To Install

The mat has an adhesive back which makes installation super easy. The material is thick, but as we said before, it is still super light, so the overall pliability of the mat is high and simple to work with.

Before you install the mat, you will need to use a rubber roller to smooth out the bubbles. You then need to cut the material into the appropriate sizing.

Once you have installed the material, you should notice the built-in indicators that show you if the mat has been settled correctly. Press down the raised dimples; if they open back up, then you haven’t rolled out the material enough.

  • No Bad Odors
  • 50% soundproofing


  • Needs To Be Rolled Out
  • Safety Gloves Need To Be Worn Due To Adhesive 


Noico 80 mil 10 sqft car Sound deadening mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Noico is another fantastic brand that will give you superior sound dampening and heat protection. They use a mixture of butyl and other lesser materials to make a more pliable material, although the combination means it weighs 0.7 pounds per square inch.

Easy To Install

As with the Kilmat, Noico requires you to roll out the material before you can peel off the protective layer and reveal the adhesive back.

Unlike Kilmat, the additional 0.2 pounds means that it isn’t appropriate for the tire wells or license plates; however, it is still light enough for doors, hoods, and panels. In reality, those three locations are the most important to soundproof as they cause the most rattling.

The materials are super easy to cut, so you only need a small precision cutter to make the incision. You can start cutting once the material has been rolled out, and then you can remove the film and press the mat onto the location you desire.

Using the roller again, remove any air bubbles that might have formed. When there are no bubbles left, you know you have successfully installed the matt.


We did notice that Noico had a strange odor to the material. Nothing terrible, but it was an asphalt-like smell that burst forth once we pulled back the protective layer covering the adhesive.

If you are sensitive to smells, we recommend using a face mask to dampen the effect.

When installing the mat, you should always be wearing durable work gloves so that your fingers do not stick to the mat.

FatMat Self-Adhesive Rattletrap Sound Deadener Bulk Pack with Install Kit - 50 Sq Ft x 80 mil Thick

If you want to deaden a van or large vehicle, then you’ll need a material you can buy without breaking your wallet. Their kit contains 50 square feet of 80 mil thick soundproofing material, but they do offer up to 200 square feet for big jobs. 

For comparison, the other kits we are looking at are around 30ft per purchase, so you may have to buy multiple to fully deck your car.

Superb Soundproofing

FatMat has incomparable control over the outside sound of your car. It reduces vibrations and distortions even if you choose to cover just the main areas of your vehicles, like the doors, panels, and hood. 

If you want to make sure that your music is clear, you will hear every boom in the bass and every twinkling high note once this mat has been installed.

Best Working Conditions

We suggest you install the mat in a warm area before starting your DIY project. This is to help the pliability of the materials and to activate the adhesion. We also recommended creating two layers of FatMat if you have a sleeper vehicle with an extra rattle.

Not Heat Resistant

Despite the heat resistant aluminum coating along the deadening material, the mats are not great in hot locations. 

If you live in a hot state like Florida or Hawaii, you may find that the adhesive back starts to melt in the summer.

  • Butyl & Aluminum Material
  • Easy To Install
  • 70% soundproofing

Dynamat 10455 18' x 32' x 0.067' Thick Self-Adhesive Sound Deadener with Xtreme Bulk Pack, (9 Sheets) , Black

If you are looking for the best heat resistant sound deadening mat, then look no further than Dynamat! It is perfect for hot state locations who want to have a quiet ride. Unlike the other mats on our list, the Dynamat is designed for your hood and engine. You can use it inside your car too, and it will do a grand job, but it’s focused on keeping your engine quiet and cool.

Heat Protection

Dynamat has the most aluminum coating in their mat, which means they are ideal for firewalls and floors. The material is easy to cut, so you can easily fit them onto your car roof, wheel wells, and hood lids, too; however, you may need two or three boxes to cover the interior of a standard sedan. This is because Dynamat is designed for just the hood.

This is why Dynamat would be an expensive choice for full coverage in comparison to FatMat.

Heavy Material

The additional aluminum does mean that Dynamat is super heavy. This means that they are great at reducing sounds and don’t have any foul smelling asphalt scents lingering around. If you have an older car, Dynamat would be able to quieten your vehicle without adding too much overall weight; however, new cars (which are more lightweight) may notice a massive change in speed.

The Matt 66 is our best overall soundproofing mat for vehicles because it is amazingly easy to install, has a fantastic heat resistance quality, is lightweight, and is super pliable. Although you can only buy it in 36ft packs, the price is a lot cheaper than the others on our list so that you can buy in bulk just like FatMat.


The Matt 66 is made out of butyl and weighs just 0.5 pounds per square foot which means it is amazingly lightweight while still creating a strong deadening barrier.

Because the material is so lightweight, you can use it in these areas:

  • Roof
  • License Plate
  • Trunk Lid
  • Trunk
  • Rear Deck
  • Rear Wheel Wells
  • Doors
  • Front Panels
  • Rear Panels

Best Soundproof Car (Vehicle) Mats

There are 3 main factors to consider when buying a soundproofing mat. They are the materials used, the characteristics created, and the installation process. Understanding these three points will help you buy the best soundproofing mat.


Sound deadeners tend to come in 3 materials, butyl, spray, and foam. Each are used for different areas in your vehicle.

Butyl is the most common material. Also known as butyl rubber, it is a synthetic polymer created in 1937. The best butyl mats have a thin layer of aluminum for sturdiness. This material is used to cover the key elements of your vehicle, like the hood and the floors, due to its insulation qualities and thin size.

Sprays are used to fill in the small and tight spaces that mats can’t fit into. They are not as good as they cannot produce a thick substance; however, they can be a great help alongside the mats themselves. If you are tempted to use the sprays alone, you will not receive a good result.

Foam insulation is lighter than Butyl and super easy to install. This makes it the preferred material for soundproofing doors. However, foam isn’t an excellent insulator in comparison to butyl.


There are 6 main characteristics in soundproofing mats, and they are the aesthetics, adhesiveness, coatings, thickness, pliability, and weight. Each characteristic will affect your mat and, therefore, the sound quality when deadened.


The aesthetics are the least impactful characteristics, however, you don’t want to buy helpful equipment which ruins your car’s look. That being said, they will be placed underneath your car door, roof or panels, so they shouldn’t be noticeable.

Most mats are black or silver, and they will likely have the maker's logo stamped on them. 


The easiest mats to install have a self-adhesive quality which allows you to peel back the protective covering and then simply stick the mat to the desired location. 

If you are hoping for an easy process, look for materials with this quality.


The best deadeners have an aluminum coating for sturdiness. Aluminum is also resistant to heat, which means that it can protect your car from the hot summer's day, which could cause the engine from overheating.

Because of this quality, you should look for aluminum coated soundproofing mats to place on the hood of your vehicle, to keep them cool.


As a rule of thumb, the thicker the deadener is, the better it will be at soundproofing. The typical thickness of a soundproofing mat is 80 mil (0.08 inches), but you can get mats as large as 200 mil. 

If you prioritized sound over the weight and, therefore the speed of your car, then you can use these thicker deadeners; however, you should be aware of how much space you have available before paying for the thickest mats you can find.

Another problem with super thick deadeners is their pliability.


If a soundproofing mat is too thick, it will be hard to bend and move with the car’s shape. 

Unfortunately, most manufacturers don’t reveal how pliable their materials are, so instead, you need to move them around yourself.

If you like to buy online, this can be a little tricky but don’t worry, our 5 best choices have already been tested for pliability so that you can be prepared for the DIY job ahead.


The heavier the mat, the more it will affect your car’s suspension and speed. If your vehicle’s suspension is being tested, you may receive more noise for the deadeners to combat. This is a great reason to aim for a lighter material.

Ideally, the soundproofing mat should not weigh more than a pound per square foot.


Before you start your installation process, you need to know what areas of the vehicle you plan on deadening. Most areas should be covered in sound deadening mats, but the tricky and small locations should use sprays

The most likely area you will want to deaden are the doors, the floors, the trunk, and the roof. These areas experience the most wind interaction and mechanical interruptions. These areas also experience the most heat, so you should use heat resistant materials like aluminum on these parts.

Most mats come with pre-cut sections; however, they will be unlikely to fit your vehicle exactly. Instead, you should use a small utility knife to trim the material into a precise fit. 

If you are using an adhesive mat, then you will need a rubber rolling tool to smoothen out any bubbles. If you are using non-adhesive mats, then you will need a glue gun to force the material to stick. 

Most manufacturers will give you the equipment you need to complete the installation; however, some will require you to buy the parts separately.

Tips For Installing Soundproof Vehicle Mats

Installing your mat isn’t difficult once you know what you’re doing. Our little tips can help you avoid any silly mistakes or aggravating errors.

Tip 1 - Wear Gloves

If you’re not wearing gloves, you’re going to stick to the adhesive layer, so you should invest in work gloves that can take the brunt for you. When you cut through a mat, you will need these gloves to hold the adhesive layer still while you use your sharp razors to slice them into shape.

Tips 2 - Read The Instruction Manual

Because the process is easy, you might be tempted to get ahead and do the job, but you need to read the instructions.

Some deadening mats have extra steps which, if not completed, will ruin your layering and make you start all over again. To avoid re-starting your day, get your head around the manual the first time around.

Tip 3 - Use Degreaser

Your car’s frame will likely be super greasy or grimy, which can be a big problem when sticking your adhesive mat on.

To prevent the mat from sticking to the grease instead of your car, you should degrease the area first, prepping it for the installation. Once the area is clean, you can begin your DIYing.

Tip 4 - Applying Pressure

Our top 5 picks for deadening mats include a rolling technique, but not all do. When you are rolling, it’s important to apply pressure to the area so that the sticky adhesive back can make a true connection.

You want to hold the pressure for 10 seconds with each roll; this is so that the adhesive has time to bond to the car’s surface. If you go too quickly or without enough pressure, the mat may not stick.

Do Rubber Mats Reduce Noise?

Rubber flooring is the best type of flooring to absorb sound. This is what makes rubber a great soundproofing material. Rubber is the best choice for reducing noise.

Is Thicker Sound Deadening Materials Better?

Thicker materials are better at soundproofing because the soundwaves have to travel through a larger and denser space to reach your ears. However, denser materials can be better than thicker materials if they create a bigger barrier between you and the sound.
