The author discusses their experience with quieting road noise on their Subaru STI, which requires a combination of multiple sound deadening methods. They found that the Crosstrek, Forrester, and Outback are the quietest options, with the exhaust being the loudest. To make the car quieter, they recommend looking into Dynamat Extreme and welding in another silencer to the exhaust and high-temp sound.
The author is considering upgrading their 2016 Base MT with short throw, as it will be their second WRX. They have tried installing sound deadening material under carpet and door panels, but this would add weight to the car. They also plan to get rid of their aftermarket exhaust.
The author shares their experience with their Subaru WRX, which has an interior and infotainment system that can be quieted by applying Extreme Automotive Sound Deadener to the doors. They also mention using Coleman sleeping bags to line the trunk and using NOICO 80mil butyl for 25-50 coverage. They also recommend Mass Loaded Vinyl (MLV) for covering 90 of the panels.
To truly quiet down on a audible level, the author suggests laying down the entire floor, including front/rear seats and trunk, doors, and roof. They recommend using Dynamat Extreme and welding in another silencer to the exhaust and high-temp sound deadening to the hood, front fender wells, and firewall.
The author notes that tire and chassis stiffness can transfer a lot of noise, making it difficult to quiet down on rough roads. They suggest starting by adding something to the inner doors, deadening and sealing the holes in the door, and sticking it on the hatch/trunk area.
📹 The Secret to Turn a Normal Car into a Luxury Car – Sound Proofing
The secret to turn a normal car into a luxury car, sound proofing DIY with Scotty Kilmer. How to install sound proof insulation in car.
How do I reduce dashboard noise?
To fix a rattling dash noise, tighten the fasteners holding the plastic part in place, use tape to tighten the fasteners, remove the part if necessary, or install an All-Fit Gap Trim in all gaps in the dash. The rattling is caused by two adjacent dash parts vibrating against each other. To fix the issue, first identify the source of the rattle by examining the area where the rattle is occurring.
Why is my car so loud inside?
Interior rattles in cars can be caused by various factors, including broken knobs and switches, natural wear and tear, and issues with the car’s doors. These rattles can become louder over time, necessitating repairs. Additionally, the car may develop problems with its vital mechanical parts, such as the engine and transmission, which can make noise and seep into the cabin. Squeaking brakes or a loose serpentine belt can also make the ride unpleasant.
Diagnosing car trouble properly is crucial for maintaining quietness and longevity. If the car is too noisy, aftermarket solutions like sound-deadening material can be installed to absorb sound waves and make the ride quieter. It’s not necessary to trade in for a high-end luxury car if you simply want less road noise. Regardless of the cause, diagnosing car trouble properly is essential to ensure the car’s long-term performance and quietness.
Is Subaru a quiet car?

Is a WRX a good daily car?
The automobile is a versatile vehicle that strikes a balance between driving exhilaration and daily practicality. It features a turbocharged engine, standard all-wheel drive, and a spacious, well-equipped cabin, which collectively make it an ideal choice for use as a daily vehicle or as a weekend sports car.
How do I sound dampen my car?
Soundproof mats inside cars can be easily applied with adhesive laminated or adhesive tape. To ensure proper adhesion, clean the surface before securing the mat, as failure could cause it to shift during movement and increase vibration and noise. Once installed, the mat should remain in place and muffle road noise. Reinforcing car wheels, especially on potholes or back roads, can also help maintain passenger comfort.
Insulated tires can reduce vibrations and muffle sounds caused by road imperfections. Overall, ensuring proper car maintenance and utilizing soundproof mats can significantly reduce road noise and vibration.
What can beat a Subaru WRX?
The 2019 Subaru WRX, introduced in 2002, is a performance benchmark for the sport compact market. It features a 2. 5-liter turbocharged flat-opposed four-cylinder engine with 268 horsepower and 258 pound-feet of torque. All models feature Subaru’s symmetrical all-wheel drive system and can be paired with a six-speed manual transmission or Subaru’s Sport Lineartronic continuously variable transmission. The WRX accelerates from 0-60 mph in about 5.
5 seconds and has a base retail price of $28, 080, including destination fees. However, there are many competitors to the WRX, including luxury sedans with higher prices and some not offering AWD. Despite these competitors, none of them are exactly like the Subaru WRX.
How do I make my Subaru quieter?
Damplifier Pro is a product designed to silence structural noises in your Subaru Outback by dampening vibrational energy. It is applied to metal parts such as inner doors, under the carpet, or behind the firewall, providing a noticeable decrease in noise levels. The recommended coverage is 60 for a massive difference in noise levels.
Luxury Liner Pro is another layer of noise reduction, with 100 coverage on the cabin side firewall, floor, and trunk. This material acts as an extremely dense extra wall between the cabin and sources of airborne noise, such as engine, tire, and road noise. Achieving 100 coverage is crucial as airborne noise enters through the weakest point in any barrier.
To reduce tire noise, Spectrum Spray Liquid Sound Deadener is a cost-effective solution for road and tire noise. It is easy to install and does not require access to the interior of the Outback. To apply, 3mm of Spectrum is applied into each wheel well, applying 1mm layers directly to the metal for a total of three layers. This can be done by spraying the liquid deadener onto the wheel well or painting it on with a brush or roller.
With just 2 gallons of Spectrum Liquid Deadener, cabin noise in your Subaru Outback should be reduced by 3-5 dB on the highway.
How to reduce car interior noise?
To reduce cabin noise in your work vehicle, follow these five tips: 1) Check the exhaust system and tires, as most outside noise comes from the road, wind, or vehicle itself. 2) Add noise-blocking weather seals, 3) Install sound-deadening panels, 4) Secure your tools and equipment, and 5) Add a partition.
Vehicle noise can be irritating, stressful, distracting, and dangerous. It can cause drivers to take their eyes off the road, leading to accidents. Additionally, the noise from the cargo area or the music on the radio can make hearing sirens from emergency vehicles difficult and affect your hearing over time. To reduce cabin noise, consider these tips and consider incorporating noise-reducing measures into your daily commute.
Can I make the inside of my car quieter?
Soundproofing your car for road noise requires a multi-faceted approach. The most common solutions include sound deadening car doors and soundproofing the floor. Other options include treating car doors with sound deadening, adding quiet rattling plastic panels, adding sound deadening and blocking material to the floor, treating wheel wells with liquid sound deadener, replacing tires, and installing weatherstripping around windows and doors.
Improving sound quality of doors is also possible. This issue is common in newer cars, as structural issues often cause issues with the door. A checklist is available to help you address these issues.
Does soundproofing a car really work?
Car soundproofing is a crucial solution for reducing unwanted noise in cars, especially older ones. It involves not just blocking outside noise but also reducing the noise made by the car itself, such as vibrations, rattling, and loose parts. Sound deadening works by buying and applying the right materials to address the sound issues in your vehicle. Whether you’re an older car owner, a car audio enthusiast, or simply want to make your evening commute more peaceful, there are numerous reasons to make your car quieter. To help you get started, this quick guide provides a step-by-step guide on how to identify and find the right materials to tackle your car’s sound issues.

You have discovered GM’s secret anout how similar a Chevrolet is to a Cadillac. For years, GM made Chevrolet, Pontiac, Olds, Buick and Cadillac, and the prices increased as you went from Chev to Cadillac, (I may have the middle order off). GM claimed the cars were smoother riding, ie: more luxurious as you spent more money. About 5 years ago, I gutted the old, stinky cloth interior of my 1989 Olds 88, and replaced it with a full leather interior from a late ’90’s Buick from a wrecking yard. I don’t think anyone had ever sat in the back seat, ( car had about 50k on it). I got the entire Buick interior, from carpet pad to seat belts. I decided to insulate above the brand new headliner I was installing, and fill in body voids below the back seat windows, and some other areas. When I started putting the interior back in, I decided to first put down some carpet pad I got from an upholstery supplier made from recycled plastic milk jugs. It also had foil on one side. The formed carpet from the Buick didn’t quite lay right, so I ended up reusing the heavily rubberized carpet pad from the Buick and the more typical grey non-rubber coated carpet pad from the Olds. So, I ended up with a lot of pad. After I got the interior done, and took my wife some where for the first time with the new interior installed, she asked me, (with no prompting or questions from me), “Did you do anything to the suspension or tires, or anyhting else?” Now, my wife doesn’t know much about cars. I was really surprised by her question.
Liked your article on sound deadening. I have a 1994 F150 that I’ve had almost since new with nearly 400,000 miles. I think it would be a good candidate for sound deadening, at times it’s hard think inside old faithful. Have you tested the difference between putting a foiled sun shield outside under the wipers vs inside on the dash? It seems to keep my truck much cooler by preventing the sunshine from penatrating the glass and warming it. Try it, you may be surprised.
When I had the stereo put in my car I had them put this stuff all over. Did not realize how loud my car was before, crazy. I know some people say stereos are a poor investment, and they are, but I am in my car 20 hours a week and it was not a major expense for me. It has made my commute way more enjoyable. The music has greater clarity and the podcast I listen are easier to understand at a lower volume level.
This is one of the things that I learned from a long time ago when I was first working on cars, & then even more when I was later working as a project expediter on high in home remodeling. Most cars & homes do not have sound insulation between the enter walls of the compartments & the enter rooms & barely on the outside due to unrealistic codes builders once I got into the field. I realized that cars were just the same as homes & needed better sounddeading, so then have always been upgrading ever since then.. 💯
Did sound deadening to my 2005 TC and it made the car way quieter and felt more premium when closing the door and moving the seats back and forth. The car had NO insulation anyway for cost savings. Also if you spray rubberized under coating in your wheel wells it will help with road noise. Most new cheaper vehicles skimp on those coatings
I like what you are doing, In the past I did this to almost all my Toyotas, however at my old age I bought a Lexus so I do not have to do that, but in cars like the 1997 Toyota Previa, I worked for several days doing that. Very nice of You showing all the folks how to do it. I wonder if you have any time left for fixing clients cars to make some money ???
The foil backed rubber is not for sound insulation it’s for sound deadening, 2 entirely different problems. To deaden the floor pan properly you don’t need to blanket cover it with deadener like you see in every article like this, around 25-35% coverage is more than enough, anymore is a blatant waste of money. Next (and this is the most important part of it) you apply a layer of MLV (mass loaded vinyl), to work effectively this should be 100% coverage and any gaps filled because this is the layer that actually stops most of the sound. Next add a layer of closed cell foam over that and replace the carpets, seats etc and your done with the floor pan. You can then strip the doors down and deaden both the inner and outer door skin and if you’re into your music try putting some open cell or egg box foam behind where the speaker will sit to help calm any back waves. After that it’s similar to the floor, add MLV and cover that with a layer of foam to avoid any rattles between the card and the door and reassemble. I like to add a layer of deadener to the roof skin, around 75% for my roof then cover that with a layer of ccf and replace the liner. You can treat the boot area the same, 25% deadener coverage plus the wheel arches then a layer of MLV and CCF to cover it all. When it’s complete the difference is profound, to me my car sounds like my friends recording studio and was well worth the considerable effort it took to do it right.
I live in Florida, I drive over 100 miles a day for work, and I’ve really been wanting to drop 500 to 1000 on some sound deadening material for my car. I preemptively took a sound check with my phone which probably isn’t as accurate as the handheld meter here, but it was 76 decibels at 65mph! If I could get that down to 50 with sound deadening in the entire floor, all the doors, and the trunk… I think my car would be a much nicer daily driver.
Scotty, years ago someone told me to line the panels in the car with GAF StormGuard. It’s a rubber leak barrier about 1/4″ thick used in roofing with a peal and stick adhesive – readily available in Home Depot. When I re-roofed my work shed I covered the entire roof with it prior to shingling (pros only cover the first 3′ from gutter) can’t believe how quiet it is in there now and I live right next to a busy highway. Next it’s going in my Civic project.
We are all the same wether of race or color or economical background.. with that being said I would just encourage all those who read this to lend a hand to someone you usually would not help and watch it make a difference in not only their lives but yours as well. Being kind is infectious once people see less hate there WILL be less hate! Let’s band together and come to one accord! Stop the hate! Stop the violence! And Stop the racism! We love cars and let’s all just enjoy them while we can still afford them! LOL! I drive a 2008 Honda Accord coupe and yes I seriously could use some sound insulation!
The truth is: most of the noise come from stiff suspension and bad sealed doors and the engine. Putting sound deadner on my car didn’t improve the noise, it even shifted the noises to a lower more anoing frequency. Im tuning my car noise for 3 years now, I know what I’m talking about! I. e. knock on a empty can and a half filled one, you’ll understand what it imediatly, that the empty one is quieter. I would recommend alubutyl only on the hood for reducong the engine volume, changin enginemounts it they are old, and only a litte alubutyl on the doors. better fill the doors and holes with light acoustic materials. Change to a much softer suspension, remove one antirollbar connetion at the rear and the roadnoises are gone. Good luck!
I drive around in a Toyota Prius that is kind of noisy….so I wear a set of Bose Noise cancelling headphones…..the stereo never sounded better. The only problem is…..when my dog farts, I cannot hear it and so I cannot open the window before the smell hits me. I think my dog takes after me. He seems to really enjoy farting.
I don’t get it. When talking about quietness. A 1994 Sentra I once had was one of the most smooth and quiet riding small cars I ever drove. While most of all other small cars are just not like it. I was that particular generation of Sentras 1991-1994. Not even the 2006 Sentra. Although it was pretty decently quiet compared to like the 2008 Corolla. I tell ya.
I agree that putting in sound deadening is a good idea, and it won’t add that much weight. In fact, it’s probably negligible. Two things, though: I wouldn’t recommend removing the roof liner yourself; that could turn into a nightmare during reinstallation, as you’re fighting gravity while doing it. That, and it will probably never look right again; leave that part to a professional. The other aspect of this is that you didn’t address the amount of noise that comes in through the windows. Door glass is much thinner than windshield or rear window glass, and it’s right at head level (where your ears are). I suspect that will now sound even louder to you, as you’ve blocked out all the other noise sources. Luxury cars also have thicker glass for that reason.
When you do this, do you apply the sound proofing material to only the inside of the outer door panel (the one closest to the outside of the vehicle), to only the panel the door handle attaches to (the one closest to the inside of the vehicle), or both? If it is the inner panel, do you cover everything including all the openings (other than those for the clips and stuff)?
Funny article 👍 when i bought in 1994 my first brand new car a vw polo 1.3, this was actually the first thing i did to it, really a great idea for anyone and any car such a different! When i was selling the car after 5 years the person who bought it was like : i tried many cars but this one is so quiet i buy it, still i thought nowadays also cheaper models already have this done in fabrication i can’t be more wrong in that one,,, sometimes it’s really horrible!!
im still young but getting up there and i only just stopped destroying my hearing driving cars: -adjust the music to a good level when youre stopped with fan off, and dont adjust it when your moving or you will damage your ears likely i think automakers should be regulated into making cars with above average noise isolation.
Be wary of sound proofing with adhesive backing – I did a layer of butyl deadening on the metal, then closed cell foam with an adhesive back which attached to a layer of mass loaded vinyl for sound proofing. Come summer the adhesive on the foam melted down and came out in sappy like puddles at the bottom. Big mess, had to tear it all apart to clean it up. Instead of adhesive products now I just staple the decoupling layer to the vinyl in a few places, and when the door panel gets sandwiched back on it holds everything in place.
Not just sound insulation… what you REALLY need to turn your normal car into a luxury car: 1) bigger powerful engine 2) wider and longer body 3) smooth buttery suspension 4) high grade leather seats 5) luxury badging Better yet… sell your current “normal” car and get a “real” luxury car. Lol. 😉
Lexus-Toyota. Infinity-Nissan. Acura-Honda……If your going to spend money on a used car, go ahead and buy the luxury version. You’ll be much happier………..You’ll have all the options without spending extra money and time converting it to the car you wanted in the 1st place. Plus you’ll have a better resale value.
the sound deadener is essentially the same material as stick on SBS roll roofing material that comes in a 3×33 foot roll for about 100.00 or 150, except its about 10x the price. Its self adhesive rubber material with a foil surface. I’m sure the manufactures have some excuses as to why it’s better but I have felt both and appear to be exactly the same.
I knew the basics but did not want to mess up my new Highlander (dyi’er). This article was the encouragement booster I needed, so thank you Scotty Kilmer. On a side note to all the negative cloggers on this site, please go away, there are serious people who just need help and reassurance… (Now its daddy time) There is nothing more worthless than expressing your opinion in a negative fashion, it helps no one and others think your a fool.. Its not to late to change, you have to want it! Thanks again Scott!!
I can vouch for this. I test drove a 2006 mercedes and it was the quietest car ive ever been in, especially compared back to back same day to nissan 370 z and nissan altima the 370 z sounded like it has no sound deadening at all, the altima was in between and the nissan altima was hallf the km and priced right so i bought it
I put sound insulation in my 09 wrangler for road noise deadening, which was nothing but a god-sent blessing, but it also improved heat insulation dramatically making the summer days more bearable for short journeys. Without it, the cooling took almost half an hour to get the cabin cool in 45 degrees c heat, now we r in the 10min range!!! I love the stuff!!
This material is to stop vibration and rattling of the panels. It is not a sound insulation. But, you is the right thing to install it. You must install the insulationAFTER that. Its name is misunderstood. It is called sound deadening which acts as a hard panel. Same as if you push the panel with your hand and the sound stops. People misunderstand that it is a sound insulator. No it is not. It acts as a hard inner panel that is tied to the outer skin so that the wall cannot vibrate uncontrollably. You should include insulation material above this material. For example a 3M Automotive Thinsulate #710 gsm.
