I spent $300 on Amazon SOUND DEADENING for a Toyota Tacoma!... did it work?

[@robertrobbins1367]

Did this on my 2019 ... I give the firmest hand shakes now.

[@markdubose9676]

Having done this, the doors make the most difference (with as complete coverage as you can manage on every surface without obstructing reassembly). After the doors, the back wall not neglecting to baffle the cab vents, then the roof then the floor. Make sure you get the rear corners in any accessible cavities. As always… I enjoy your videos!! Thank you for the hard work and for being an advocate for the Tacoma World!

[@Ishiisan]

When I talked to the audio engineer who works on a luxury car, she told me use more foam mats than the sound deadening mat. Tap on the metal panel, add sound deadening mats until the vibration from the panel is reduced. Then use the foam lined mats to create air pockets to capture sound. I tried this method and it worked well.

[@wilmafingerdoo2690]

I would NEVER take this project on, but i watched it anyway because watching Chloe do things like this really intrigues me! Love helping her channel!!

[@ChloeKuo]

Well thanks 😊

[@JoeSlaughterJr]

I did this on my 2023 Tacoma. I think the majority of the sound comes through the back wall. I noticed a huge difference after sound deadening. People that ride in the truck say it’s like riding in a luxury vehicle.

[@indman101]

Back Wall? behind the back seats or fire wall?

[@BrianWaller-qe7gr]

As someone in the car audio diy sound deadener is a must. Sound skins, and killmat is probably the best. It does help

After watching a TON of these videos on sound deadening I’d say you did a GREAT job and should be proud. Thanks for sharing.

[@emiliosrucaj]

Listen I'm doing my own truck f-150 nearly a 25 days now and I'm on the 3rd door, it is not an easy job at all, you did a good job no matter what! It takes me about 6 days to complete one door. I mean I'm doing mine to the max possible. 110% coverage all panels inside out 2 layers tar mat with aluminum + 1/2 dense foam with aluminum layer, for superior enclosure! It's worth your time especially if you are doing for your self! 👍

[@KyoCujo]

I genuinely salute your DIY spirit, this seems like so much effort. Fun vid to watch though !

[@Par_x3D]

I did this in my 06 Odyssey after lots of research and spent about $350 not counting tires. The biggest reductions in NVH intrusion came from new tires (bridgestone weatherpeaks), followed by carpeting my front wheel liners. The rest only lowered the noise floor modestly but significantly shifted the road noise pitch to the deeper frequencies, making them less noticeable and intrusive. I went with silless butyl dampening mat, self adhesive closed cell foam and frost king cotton/denim insulation (similar to what the Tacoma had on the floor). Many people overspend/overapply butyl sound dampening mat, 100% or majority coverage is not required. I only did 1/3 of my roof with the butyl and it made a huge difference to quieting and deepening rainfall, road noise impact was negligible for me. I used all 3 products on the floor primarily towards the front, on the doors and a little butyl on the rear hatch and roof. I wanted to see if the modern industry practice of carpeting wheel liners was doable at home for cheap, so I thoroughly cleaned my liners and epoxied 2 layers of thicker moisture/mildew resistant carpet/fabric to the tire facing side of the wheel liners. This ate up the most noise of any product application. I didn't carpet the rear liners but I double layered the cotton insulation over the inside wheel wells over a layer of butyl and foam. Compared to when I first got this thing with the older dry tires it's like driving a 2 generation newer vehicle in terms of NVH. Of course, the time investment of stripping your interior and headliner for marginal benefits are pretty involved and annoying. I'd only really recommend it on something you absolutely love or know you're keeping long term as a daily. If I did it again I'd just go with nice tires and carpeting the wheel liners. I had the interior and headliner out for wiring my back up camera and electrical system for my camper mods so it was a 2 birds situation.

[@timstanton2241]

I added the sound deadening materials in my gen 3 a few years ago. I included the back wall. There was nothing behind the plastic of the rear wall. I didn’t do the ceiling. What I found was that at 45-50 mph, there was significant improvement in the quietness. However, at highway speeds there was very little improvement. The wind noise could not be overcome. I would still do this again. Thanks for another great video. Best!

[@sdboy1978]

When I added the dynamat in a different vehicle, it took away the rattles when mounted at the speaker locations and behind them. It helps when added where subs are located but I didn’t notice any reduction in road noise. It just helped the audio system

[@jamram9924]

I’ve installed upgraded sound systems in all of my cars. One of my favorites was Dynamat in the doors and around the new speakers. It increased the bass response/sound with deeper bass sounds. It helped quiet down the road noise a little but mostly used for that improved sound coming from the door speakers.

[@knives01ng]

I did this to my Mitsubishi EVO X (used the same material as you did) - LOVE doing this mod and cannot wait to do it again to my taco and miata! One thing I do differently is I use a heat gun for adhering the material to the chassis and also wiped down surfaces with isopropyl alcohol with a microfiber prior. This is such a great mod though it takes a Corolla to a BMW. Would love to see you do the back and the headliner (roof) - it makes a good difference.

[@808_TexN]

A couple years ago I did only the doors, panels, and hatch on my 4Runner and it made a big difference with the audio. Not sure about road noise since it’s still fairly loud but stereo sounded more solid. Also makes the doors feel solid when you open/shut them.

[@Antiyoutubeyoutubeaccount]

Did this a year or so ago on my tundra and was pretty impressed with the difference. I initially did this on my Jeep’s roof a few years back and that was 10x more effective than the tundra was and 1/10 the work lol Still worth it for the DIY’er that isnt afraid to take things apart

[@honeybadgerwrx]

The back wall will help for sure, and the roof is SUPER worth it. When you're done, you can barely even hear rain when it's raining outside!

[@ianabelein2821]

I did this to my Tacoma as well. I went the extra mile and added 2 layers on every surface I could. I also added some high density foam to the vents behind the rear seats. Definitely noticed a huge difference in the way the doors close and overall how the truck feels while I drive. I also noticed a significant reduction in road noise and wind buffeting.

[@rodkubo5679]

I applaud your patience and working on your tried and true platform even though you like the upgrades to the new gen.

[@danek893]

i did that to all 4 doors and result is really good, less sound leak to outside and music is much better and you fell it every time you closeing the door, althought i like NOICO more then KILMART a bit more expensive but products is much better quality, i have them on over 5 years now and it holding really well.

[@jogulaps5448]

I planned to upgrade my speakers, so I went ahead and purchased the killmat. I just did the doors, and what a difference. Besides tapping on the door to hear the sound difference, closing the door feels solid. I'm very happy with this upgrade. Oh, and i didn't flatten the tiny square pattern . That killmat is sticky but manageable to apply.

[@edwardfitzpatrick9363]

I added sound deadener around 4 interior speakers. I also added some foam in front doors to cancel out negative sound waves. I have a sub in trunk and added sound deadener to trunk lid and it made it sound way better. Great work on your install. 👍

[@dtcolipapaify]

I just had my sound system installed…I went will higher end stuff…so sound deadening the doors and rear cab wall is the norm of the build…side benefits was a quieter interior…a lot less road noise…anyone going aftermarket with speakers and amps…this is a must…I went with Focal…Arc Audio and Digital Design…no use to spend all that money and have a noisy interior…

[@kc2743]

I did this on my '24 GMC Canyon AT4X....went above and beyond on the doors because of the annoying bass rattle on the driver's door (gone now). I used the extra box that I bought years ago when I did the same to my '19 Ram 1500...totally worth the time and money:)

[@nelsyoung833]

Well done. Consider deadening the ceiling and the hood as well to make it complete

[@honeybadgerwrx]

You put in some top shelf work! If you really want your current work to shine brightly, you should consider putting some Mass loaded vinyl

[@davidschwartz3427]

It may not have made a difference in overall volume from road noise, but you can clearly hear a difference in higher frequencies. I bet that makes a huge difference particularly on long drives.

[@rickyALH]

Don’t have a taco, but I did this on my 18’ forester. Took a couple days to do but entirely covered from ceiling to floor, and front to back (including weird places like the spare wheel compartment and all the way down all pillars) It definitely made a contrast difference for me in terms of road noise (I run wildpeak ATs) and completely killed the minor wind noise I would have at highway speeds. May have been overkill and not worth it for most, but considering I spend about 50,000 miles a year in it, was a no brainer to me.

[@jose12onlinetm52]

Love the video! So in depth I’ve done the same to my taco just I have also done the engine hood, wheel wells, roof, back panels, and it does for sure make it quite nice to drive. Ultimately you stop noise from one area and notice noice from another. That’s why teslas have the double pane windows since wind noise is noticed more when there isn’t other noises to distract you from it.

[@johnl9135]

I think you've done a great job with the sound deadener. If you're into car sound system, sound deadener is a must. I used to into this kind of stuff when I was in high school back in the days. My friends and I always DIY our sound system in our vehicles with new amps and car radio? Back then Alpine car stereo, Rockford Fosgate amps, kicker and Rockford Fosgate speakers was our go to system. 😂

[@hongmlamg]

I did a similar process but I added mass load vinyl. It helps with the noise. it changes the noise from high wind noise to a lower frequency.

[@teddyg210]

I put sound deadening on my 2018 Subaru WRX that has many of the same issues with noise as the Taco. I placed it on the doors, under the rear seat and in the trunk area. I also sprayed boom mat over the adhesive mats I placed on the metal to fill in the gaps. This made a big difference but it is not a luxury car experience to be sure. Still a lot of road noise and wind noise but much better than factory. The radio sounds better as well. For me I will just use the spray boom mat on the floor and roof if the noise becomes too much in the future.

[@timsiemssen1148]

So true! As i drive mine home from the dealer, i couldn't stand the road noise. Thank you so much for this tip! ❤🎉😊

[@RealLifeLarp]

This is awesome, I did it to my Chevy S-10. It really made a difference, I did do the roof and back too.

[@kels884]

[@timfrancis6774]

this is project number 3 on my list, then putting in new speakers in rear access doors. thank you for this, i appreciate you.

[@user-ej1bq4bq2w]

Keep in mind, the rear speakers in the 3g tacoma is severely under powered form the factory head unit. Go into balance setting and fade it all the way to the rear to highlight what I'm describing. New speakers alone are going to make no difference at all. You will need to run power from an aux amplifier to get any real sound out of the rear doors, factory speakers or aftermarket.

[@barbecuetechtips6024]

Cld aluminum tiles with butyl backing are to prevent vibration and panel resonance. Not really designed for sound blockage with that thin aluminum sheet. Closed cell foam as a whole isn't effective due to the thickness needed and coverage needed to have an improvement. Mass loaded vinyl is what stops the sound waves from entering, cld tiles for resonance, and 3m thinsulate fiber mat for air space sound wave absorbtion. A professional measuring microphone is needed for accuracy. Ipad and phone mics are terrible for this job. Doors are the biggest difference overall. These knock off companies on Amazon and online use toxic chemicals and materials for sound deadening FYI. Second skin is the brand I go to honestly. They have a memorial day special. Basically materials block sound waves or absorb them.

[@reyflores4606]

The stereo will sound better without that annoying door resonace.

[@Mosrmosr993]

This. Thinsulate

[@hillrunner2]

Wow! That’s impressive and informative solution to a noise complaint for trucks. Enjoy your content 👍👍👍ℹ️

[@TheCrusher2112]

I highly recommend deadening the roof before everything else, especially if you have a roof rack installed on your Tacoma. The roof makes a huge difference for wind noise. I also did the doors and floor, but those were not nearly as much improvement. Doing the doors also improved the audio quality inside the truck tho

[@voicesinkennyshead3691]

Holy Smokes, props to you Chloe 👍, I would have lost half of the bolts and broke several clips

[@gio.rodriguez]

[@NoxiousWZRD]

great video, gave me confidence to do this to my 10th gen suburban 2500. one safety suggestion. anytime you are connecting or disconnecting airbags you should disconnect your battery first.

[@tuffytoys9707]

! I've Seen enough videos on sound deadening a Van to Know that you would not get much Benefit from doing the Floors. The Material would have made a Bigger Difference with the Back and the roof as you Stated. Also the adhesive Vinyl, if placed on the door skin in applicable areas and the Killmat on exposed metal on the speaker side would reduce the Sound "Leakage" to the outside. Also on that same point some better speaker Rings that "Push" the Sound Through the doorskin into cabin also do Great. The only Real benefit of doing the Floors is Better Temperature control for the hot or Cold Weather!

[@bakan117]

One thing I didn't see/hear mentioned was disconnecting the battery for safety if your seats have airbags as they can deploy when connecting/disconnecting the plugs. Otherwise you did a great job!

[@scottibass]

most dampening mats don't block sound, they prevent resonance from large sheet metal. The biggest bang for the buck are the doors exterior skin panels and ceiling. The floor is already loaded with sound deadening and carpet.

[@IamLaR1]

Since you have extra material, I would def recommend doing the back wall. From all accounts it make a big difference. Well done though ma'am.

[@MrYour1Fan]

I was thinking of going same thing to improve the sound inside my truck. Good job 👍🏼

[@k.skyl1n3zz]

You may probably want to add closed cell PE foam from Siless to layer on top of the Kilmat/butyl rubber so it decouples actual sound and it also does reduce sound waves a lot more up to 2-3 db more on video tests, then another one is MLV on floor only but its a lot of weight and costs a lot. Another spot you may want to look at is the wheel wells from the front as they also are the main cause for road noise too and same goes for the hood/bonnet. This should reduce another 3-5 db if all the things here listed are done (excludes MLV)

[@DonaldChapman]

Finally, The first comment! Love your videos! Keep up the great work!

[@slyslug88]

Awesome video - been wanting to do this for a while

[@fhuugndsrzxpieobd]

Another point of view I know is that sound dampening with double glass. But it's difficult to find, usually people get double glass from another country market version or something like that.

[@timmyireland1]

For the sake of time saving I would do the doors first, and possibly the roof, and then hear the result BEFORE doing the floor.

[@emperor91108]

I could see how only doing doors would be best bang for your buck

Not surprised the decibel meter didn't show much difference. You would have to upgrade the windows(if the make them for taco).

[@ImOnlyaMAN88]

For the doors, if you get a dent, the PDR guy would be pissed.

[@Al-id9nw]

In my Tacoma the rear panel was actually the biggest difference for me. While you are in there ensure you "vents" are seated nicely and seal them up as well or you can get water ingress through there. The rear is a large piece of metal that resonates especially if you have a custom exhaust like I did. Nice work though. Only thing I used that you didn't was a heat gun so ensure adherence to the metal.

[@N6EAJ]

Agree. In my 1st gen Tacoma, the back wall rang like a bell with a modest 10" sub. There were ribs in the back wall to stiffen it, but it still vibrated with the sub.

[@JasonExplainsThings]

Awesome Chloe! I may do this and upgrade my speakers at the same time. How long did it take you to do this project?! I’d imagine a good 8 hours of work?

also remember to wipe clean the inside of your door before the panels because they can be very dirty if your truck is a little older.

[@andru12qw]

Do you know the name of the song that starts at 1:32? Great video! Btw. I did this to my car and only did the doors. Helped a lot with the sound system and some road noise. If I ever do it again I would do my roof next as that has the least amount of sound dampening I feel.

[@LerrySanders]

Its funny people complain about how loud the truck is, have never really been in a car that doesnt seal up well. Im looking at you Subaru, or been in a soft top wrangler at highway speeds. The Tacoma is fine. I mean it could be quieter, but its fine.

good job. You only really need to cover about 20% of a surface to get the deadening effect.

I hate rolling the kill mat! I’ve tried knock offs that are way easier to roll but the kill mat is the only one I’ve found that is non toxic. In my experience, rolling it completely flat makes no difference to the end result of the sound, and with this stuff being extremely sticky, just do your best and it’ll be good.

[@ChloeKuo]

Reading this made me feel better about myself 😅 I was struggling!!

​​@@ChloeKuo if you do this again in a different vehicle, instead of a roller, use the back of a screwdriver handle. Rub the killmat with it. Much more effective and quicker. You'll want a screwdriver handle with a nice rounded smooth end.
