The Cheapest and Best Sound Deadening Mat for My Land Cruiser! 

When I did the same with my ‘06 Tundra, I pulled the carpet out and called a local carpet cleaning company and signed up for their “3 rooms for $99 special”. When the tech showed up I told him 2 rooms were in the house and the third was in the driveway. He did a great job and the carpet looked pretty darn good!

Dude, the first minute of what you said is literally me rn. Feels good to be able to have money for my projects but different priorities now. 😅 wish I had a chance to meet you when we were still a local to the 559.

I put the same amazon brand deadner on the ceiling of my Honda while I had the headliner out. It made a HUGE improvement in getting rid of the tin can sound, ESPECIALLY when it’s raining: the sound of the rain drops hitting the windshield and backlite glass is louder than the ones hitting the roof.

Replacement carpet is also available with something called "mass backing" which reduces sound transfer. Its a big investment on an SUV at around 700 bucks for ultra plush carpet with mass backing, but it is great at making the interior look, feel, and smell new, especially on older vehicles with damaged carpet (stains, cigarette burns, tears, or wear through). Ive used stockinteriors for carpet on several projects, and their molded carpets have always been top quality, IMO

It's amazing how much effort you have to put into a Toyota to make it more pleasant for actual driving.

A trick I've always done is just remove the weather barrier all together and put a second layer of sound deadener in place of it. The layer on the outer skin deadens the sound of the metal itself and the inner layer helps deaden the sound of the hollow of the door, plus it better isolates the rear wave of speakers from the cabin area.

Some advice, start with fixing all the window and door seals. The wind noise is going to be most noticeable. Then listen for the actual sources of vibration based noise and treat those areas. When the first source of noise is reduced, you'll then get a new noticeable source of noise. Keep going. Do the tap test to find resonances.

Doing the fender wells definitely helps especially if you go to a more aggressive tire

Like you were sayin it’s very difficult to show the difference that is made for far too many reasons to list but I think the most important one is noise reduction that isn’t truly shown on a decibel meter. The meter just reads the loudest frequency registered, it doesn’t show which frequencies were reduced and by how much. For example, we tend to be very sensitive to the 1k-4k hz and sound deadening/absorption mainly reduces that range. So you could actually have a 20 db swing that would go unnoticed due to its limitations. Second, the lower frequencies are very difficult to absorb due to the wave lengths being so long, it would require several inches of padding up to several feet depending on which frequency you are trying to limit. Luckily, the lower the frequency, the more pleasant it’s generally perceived.

I put sound deadening materials to my E28 floor, roof, doors, pillars and wheel well. It made a significant difference in reducing vibrations and rattles. But the biggest difference in my case was when I put those soft sound deadening foam and carpet bits of a BMW 7 series, glued thin carpets on the inner fenders like what some new cars have and replacing every rubber seals on the doors and windows, it greatly reduced the road, tire and wind noise, the lot.

I put some under my headliner .. helped with heat transfer in the summer too

Time is the issue for most of us and/or a place to work on our vehicles. Nice video.

The opening lines here really, really resonate. I've had build sheets, lists, and bookmark folders for years now of all of the cars I've ever owned, currently own, or aspire to own. Gotta love it!

almost ALL resonate noise in a vehicle that large comes from, firewall, doors, rear gate... and believe it or not the roof of the vehicle acts like the skin on a drumhead. All road vibration while driving resonates UP, with all the effort you put into that you should do the ceiling & I would bet you would notice an Audible difference W/O the Db meter. I know I did, and I ONLY did the side panels doors and roof. LOL now mind you having crappy worn or chopped, or semi knobby tires doesn't help either(a good touring tire will kill a ton of road noise) Good Video!!

Thanks for the heads up about the sound deadener. It's on my project list.Before I've removed carpet I took it to the car wash in the back of the truck and power washed it. Works like a champ.

I have the same leaking rear window...looking forward to seeing the fix for it! Great idea on the sound deadening too...more projects!

I used it in my old Altima and I was extremely impressed.

Having and using a better roller than the one you use also helps tremendously

I bought the Amazon basics stuff off return pallet warehouse for $1.50 a box. 10"x16", normally $40 a box. I managed to get 10 boxes for $15. Love the stuff

That is a HUGE difference! Nice vid.

I remember adding sound deadening mats in my friend's Toyota Corolla as a teen. He could only afford to enough to install them in his doors first. It made a big difference. Then we installed some on his roof and that made a huge difference. I have a 2015 Toyota RAV4 that I've been tinkering with and this might be my next addition lol

Those carpet cleaners/ pet vacs are great for lazy detailers who just wanna get the top of carpets clean and make "lines". If your gonna put in the effort and remove the carpet, lay it out flat, use a pressure washer and some APC. Best thing you could ever do.

6 to 7 is HUGE. Remember it's not a linear scale! ❤

It's so much nicer driving a car that has been sound deadend correctly. Even without having a big aftermarket stereo, it makes it so much quieter while driving. 👍

I bought a cheap metal IKEA cabinet - threw a pack of those same sound deadening pads it it, and now it's just a dead thud on every panel 😄

BTW, every three decibels is a difference of two times the previous value.

Great video! Yes db scale is logarithmic, 3db is a double or halving depending on direction. 3db is usually what it takes for the human ear to notice although come can notice 2db. 6 db reduction is excellent!

Love your videos man. I got me an 40th anniversary 80 this year and I love it. Your videos give me a lot of knowledge on how I’m gonna tackle my projects on it once I can afford it.

I did it on my 2015 kia rio! I did not do the floor but the hatch and backseat are covered, plus doors and rear quarter...huge improvement !about 100$ and an afternoon work time. i used amazon basic too, great product...my next car will get the same treatment!

To anyone wondering if it's worth it YES it is. I have a 95 suburban and i used lizard skin which uses a special spray gun on the under side or the cab and a generic something like what is in this video on the inside and it blocks out most of the noise from my nobby 35'' tires. It was one of the best upgrades i've ever done

I so get the opening. I had a badass 65’ Mustang my Dad and I built, but I couldn’t afford to what I really wanted. Later I had an 85’ GT, couldn’t afford to modify it. Now I’m about to retire for the second time. I just naught a $1,700 tool for my workshop and I’m shopping for a 66-67 Shelby, or a 66’ convertible to build up. I got the money, and about to have the time. Oh, on the sound deadening I used expanding foam in the body parts I couldn’t get to. I used neoprene matting between the skin and interior panels. I used some heavy duty sound matting for the flooring and doors and hatch. I have an 85’ Cherokee I take hunting. It’s rigged to camp in and secure my weapons. I have a great sound system in it. Now I can blow money on my cars and hardly think about it. Keep it up!

Great video! I'm a total newbie at this stuff and found this really helpful. Gonna try using the Amazon stuff on my Highlander. Also, in terms of noise reduction, I have noticed that sound deadening makes a HUGE difference at reducing the droning noise of A/T tires on pavement. My best friend did some sound deadening in their Jeep, and while the road noise only got a little quieter, it got WAY less annoying. Very important when you have to drive 2 hours to get to the trailhead!

You can cut up and use a clear shower curtain as the door barrier. They sell them for $1 at the dollar tree 😊. One should be enough

Bro throwing away rare earth magnets from rock quality we can’t even mine anymore 😢🎉 great video on sound deadening! Good work!

Nice job. I did the exact same procedure with the same product on my 97 LX450. It’s also a great time to change out the fuel sock if you haven’t yet. Great build and hope to see ya on the trail someday.

I’m definitely going to put some of that sound deadener in my doors and quarter panels. And that tip about how to fix the door panels with the superglue Is a game changer!

Don't forget the headliner for cutting the wind noise. awesome job.

Closed cell insulating camping pads work well for insulation.. 1/2" thick so you must consider that. I put it over the butyl deadener.

I used this stuff in my doors of my crv and it works great and cheap

I've used B-quiet products in the past with excellent results. I run mostly minivans which have a LOT of relatively flat steel to resonate. Adding carpet to hard plastic interior panels both reduces noise and much improves the feel when touching those panels. A dash carpet reduces sound reflections as well as light reflections from the windshield. Spray foam (Great Stuff or equivalent) in hollow panel areas absolutely kills resonance. If any of your doors have only a single seal adding a double or even triple seal can really help. Higher trim levels of some vehicles or different "brands" of the same vehicle often have better door seals which you can add. Different brands of tire can make a significant difference.

Feel you on the money for projects. Bought a 2001 Camry, 16 years ago, and only just started. I blame 4 kids haha. But what i wanted back then has changed today. Interesting that the amazon basics did so well. I plan to use an Australian made product for obvious reasons. But it did really well. Should be noted, due to the way the decibel scale is, the quieter you make it, the more the measurement will jump around. But 60s is really good.

Great job. Huge difference.

I've done the same on a 99 Tacoma and 89 4runner. Makes a huge difference on these old trucks. My next tackles on the 80 are both rear door lock actuators don't work and my windows are so slow. I think I already purchased the runs, but a bottle of silicone spray actually did wonders a couple years ago. I figure, doors off, replace speakers, locks, refresh window grease and sound deadening will be a good 3 for 1 winter project .

Did my 97 80 last summer with Amazon brand as the mat. Worked great. Thunk test is real!

Love your videos man.

Might as well install some level IIIA soft armor in the doors and quarter panels while your at it

Great video bro

Being a former car audio installer, one of the biggest culprits for road noise is the roof and doors. When I would get sound deadening projects, I would do both.

For the sound coming through the firewall, whenever you have a dash panel off cover it in the foam or sound deadener. Stops vibration and reduces the noise. You can also put some sound deadening on the engine bay side if you really wanted too

I just use Lowe's roof flashing. Has the tar and the foil. Works great and cheap as heck.

Great video. I just wanted to add my 2 cents. The decibel reading is a combination of sounds, not just road noise. You also have to factor in the noise from wind, engine, and tires. Tires are the worst because the type of tread can add several decibels depending on the type and how it interacts when in contact with the road. Add material to the underside of the hood if it doesn't already have it. And try adding some material to the inner fenders to absorb noise at the source. Luxury car manufacturers target specific areas of the interior and it looks like a patchwork of sound absorbing material when you take apart the interior. I suspect it's because applying soundproofing to the entire interior of the cabin won't result in a huge significance in sound deadening and it's not cost effective. Luxury auto makers also select tires that are quiet and I read somewhere there is a tire made with sound deadening material. Manufacturers also use special isolators in suspension components for their high-end cars. Rolls Royce had to remove some of their sound proofing because it was too good. Drivers were complaining that they didn't have a sense of being connected to the road and it was an eerie feeling while driving.

I used this exact stuff in my 2015 tundra about 2 years ago and it’s really really good.

Good stuff! sound deadening definitely helps

Run some weed whacker string through the sunroof drains. Carefully. If you have a damp interior, they’re probably clogged.

17:00 that's a freakin' genius idea, thank you for sharing that strategy!

I've used 1/2" recycled foam carpet underlayment as sound deadener in the side panels of a VW van. It works quite well with just some spray adhesive.

even when u were in the car explaining about DB rating your voice sounded clearer and sounded like there was less noise

Great tips. Love the super glue on the masonite. A big contributor to driving noise in general is noise from the roof. Wind and vibration. You don't need to insulate/add material to the entire surface, just enough to add weight as it will make a significant difference as well.

Love the channel. Make more Landcruiser videos!

I can hear a difference in road noise without the numbers verifying it. Good job I'm sold on that product, thanks...

Good work! I like a wood grain shift knob.

A 3db reduction is very noticeable to the ear. To increase the sound by 3db takes a doubling of the power of an audio amplifier. So a reduction of 6db is pretty big for an ambient noise drop. Nice.

Amazon for the win! 👌🏼

I have been really enjoying your videos. Thanks for taking the time to post them on RU-vid. I just finished installing the four door speakers last week using your guidance. So thanks for going in depth on the install. For the sound deadening, I think I would like to start with the quarter panels and doors. How much material would you recommend purchasing if I only did those things first? Another thing I would like to see you try is to figure out a decent subwoofer option.

I bought the Siless version. Was a bit cheaper than even the amazon brand. Works well so far. Have not got interior back together yet.

I found noico 8 mil to be about the same as dynamat extreme, although a little less pleasant to work with. Honestly though, these products mostly work for vibration, not road noise. The biggest difference maker for road noise (BY FAR) will be a second layer of carpet.

Nice job

Rear tailgate/trunk helps a lot

6db is equal to about a 66% increase in volume to the ear. A doubling of the SPL (volume) to the ear requires about 9-10 db increase in output or the reduction in noise to overcome. All things considered equal it works like this. 100 to 200 watts, 3 db. 200 to 400 watts, 3 db more or 6 db over 100 watts. 400 to 800 watts another 3 db or a doubling of the volume to the ear. 8 to 1 ratio when sing wattage is the mechanism for the desired increase in volume. Since the same works in reverse, 3 db decrease in noise, same as going from 100 to 200 watts, another 3 db down, same volume increase as though you went from 200 to 400 watts, etc.

Researching sound reduction materials for my CNC. Pretty sure imma go with the automotive stuff here.

The science might have been a bit more accurate if you hadn't been going faster in the before video - i.e. 40mph before and 35mph after? That alone would probably account for 50% of the apparent decibel reduction?

A lot of people don't realize that most Amazon Basics products, are actually just other really well selling products, that Amazon has branded with their name. I remember buying some Amazon Basics knee pads years ago, only to find out that they were exactly the same as the Home Depot Husky knee pads.

this proved that you can achieve good or even better results yet for a cheaper route. yes it's somewhat a tedious job and in deed you had it done pretty neat. good job. cheers! 🇵🇭

Just did this on my old c10.

Dam dude. The back of the truck looks great!

Adding some kind of radiant barrier material to the passenger side foot well and around the shifter makes a difference in the heat on the floor from the exhaust

Really surprised that you didn't do the roof. That sometimes makes almost as much of a difference as doing the floor will

Hi mate just watched this vid and realised, it is not that hard to sound proof and heat proof my 80 series Landcruiser. Will pick up what I need to morrow and get into it. All the best from Perth Western Australia Peace bro

I've always wondered and thought the ceiling/roof would be one of the most ideal spots for sound deadening/dampening would make a big difference, especially it being the one biggest one pieces of metal that gets tons of wind, rain noise and usually has little to no sound dampening.

Thanks!

Didn't really need the decibel app, for confirmation. As long as your recording settings, and the mic you are using is the same? You can hear the difference, between the pre, and post, of the soundproofing job. Your voice is much clearer.

Did you end up putting sound deadening over the rear wheel wells? If not, I bet that would help too.

Great job! You should check for rust at the bottom of your inner panels below the sliding rear windows. They are really prone to rust there. There's a drain plug there as well. It really sucks repairing that section if you have to because of rust.

Nice install. I've used a material called Quik Roof that has worked great for resonance reduction. No smell, sticks like crazy. Just another option.

My guy…why you letting out the secrets…now how am I going to get it for the low anymore😂😅. At 43 my life is project classic SUV’s I “give” to my daughters🙌🏾😂.

You can add it in roof also to get maximize results

What would you sound deaden behind the dash….mine is out currently…not a lot of room back there to put sound deadening material??

Ballistol can bring failing window seals back to life. It's great at restoring plastics as well. You just use it as a cleaner and then buff it out. You also need more than just sound deadener to do this correctly. That sound deadener is just the first layer for acoustic management and it's not actually designed to block out road noise. It's more for vibrations and insulation. EDIT: I see you got the closed cell foam layer as well, that's the actual sound deadening layer.

Dude I thought I was the only one in the world that spent hours and hours writing detail lists of upgrade parts and theoretical builds in the future!

Feels like big difference from 1st test to the installed one just from the sound of the video here

curious if youll do the roof might only help though when its raining but still

Awesome project dude! I'm planning on doing the same to my '95 Land Cruiser. Just wondering, how much of the Amazon Basics Sound Deadener did you end up ordering, to do the whole vehicle?

I have several goal books with complete build parts and pricing and then Amazon list for each. I think I have a good 20,000 separate parts in the list

This is a great mod. The difference speaks for itself. I'm not sure if you'll be able to do it or not but people are now swapping a 100 series or even 200 series dash to older land cruisers. Makes it look way more modern from the inside.

It's a lot of work. Roller and utility knife are your best tools. I've been doing this to every vehicle I've own since the late 90s.

Knob is nice

There are two ways sound is transmitted, STC, and IIC, one is from impact, and the way to oessen that is typically from adding mass, imagine punching a concrete wall, people won't hear in the other side. Then imagine yelling at the concrete wall, concrete will transmitv this type of dound, abs the best way to learn it is by isolation.

Another awesome video bro. Did you ever find where that water leak was coming from? Noticing the same leak on my 93 LC80

It's a lot of work, but a 1 cm wool carpet makes miracles.

Would that help with roof rack noise if used on the roof?
