How to Sound Deaden Car Interior - VBL #7 - CarAudioFabrication

[@russryan4632]

One reason to put second skin all over the floor is to reduce heat in older V8 cars. I used their "Firewall Thermal Coating" along with the Damplifier Pro and it dropped the trans tunnel form 160 degrees to 78 degrees (which was room temperature).

[@SecondSkinAudio]

+Russ Ryan Nice to hear the results you wanted were achieved......thanks for the shout out!!

[@dobledekersoulwrekr]

Second Skin Insulation ...isn't mlv supposed to work with a foam under it to keep a gap or from the mlv touching the surface you are isolating it from?

[@SecondSkinAudio]

Yes double deckersoulwrecker you would want to have at least a 1/8" Closed Cell Foam (CCF)layer between the metal or foil top and the Mass Laded Vinyl (MLV) to decouple the air waves and keep the hard surfaces from creating noise. This is not our build, but Mark is a very talented installer in the industry so I am sure there was a good reason for this application (usually it is because of clearance restrictions on carpet re-apply in cars likes Porsche and Prius) and every single build is different and requires different strategies. This very reason is why we created the Luxury Liner Pro over 15 years ago which has the CCF infused onto the MLV already and will not separate and is so much easier to install then doing CCF and MLV separately.

[@dobledekersoulwrekr]

Second Skin Insulation Thanks for the response. I wasn't sure if it still worked this way

[@lorbofpower947]

Thank you for sharing your knowledge with us. I never considered the vibration from body clips and wire. Whats more your explanation of the different types of sound deadeners and their uses helps greatly. I am now excited to tackle my 03 suburban build.

[@iChubbs_81]

6 years passed?? Now youre waayy up there bud🤙

[@a-75n5lee4]

I took some of the ideas from Gary Bigg's Regal using lead and fiberglass to stiffen and add mass. Instead of expensive Cascade lead septum, I used 1/64 lead sheets to the under foot area's applying with butyl rubber roofing adhesive. But like him I used lead shot with fiberglass and 3 layers of Noico sound deadening, which I concluded just as good as Dynamat Extreme in my subwoofer enclosure.

[@vongdong10]

I'm amazed how you got everything to fit back in after all of that sound deadening.

[@CarAudioFabrication]

A Vong Careful planning and keeping the thought of "How does this fit back together" in the back of your mind will help make the process more smooth. It really wasn't too bad. Carpet is much more forgiving than door panels.

[@christopay]

Most technical sources recommend a closed cell foam between the car and the Mass Loaded Vinyl. Can you please tell me why you didn't implement that step?

[@dewyatt]

3 years later -- I'm pretty sure that Luxury Liner product he used has two layers: CCF and MLV.

Hi there! I'm one of the new subscribers. I'm also one of the ones that can't afford audio system right now, but I will in the future. Not a crazy system, but enough to have good sound. I can't do massive systems as I do use hearing aids on both sides, due tinnitus and bad hearing in general. But I do love your videos, and keep them coming :-) Chees from Norway :-)

[@BrianFrishcosy]

That is a lot of work, and you make it look so easy.

[@CarAudioFabrication]

Brian Frishcosy To be honest, its not that bad. One of those things that gets easier with practice though for sure. Thanks for watching.

[@BrianFrishcosy]

Thanks for the helpful videos

[@justingardner4555]

How many sq ft of CLD and MLV did you use in this video?

[@genericdude6551]

It would have been nice to see a before and after noise level measurement. I'd hate to spend several hours doing this and not getting significant improvement in noise reduction. Looks like all of this will add to the weight of the vehicle but I wonder if that's a significant issue with gas mileage.

[@NihadH]

You said that you remove the OEM CLD material from the panels, but you stick your CLD sheets straight over the OEM CLD material (the yellowish layer in that car) all over the floor? Also, what about the principle of 25-50% panel surface coverage for the CLD layer? You did not mention it and I do not see you practicing it in this instance. You went for the 100% coverage. Why so?

[@actionjackson1971]

Can't speak for Mark, but for CLD on my car's floor, I just did a tap test and applied to areas that needed it the most. I even had to apply it right over the factory deadening b/c it wasn't doing a good job. I ended up covering up to 80% of my floor b/c it needed it the most.

[@NihadH]

ActnJksn If my thinking is correct, factory CLD layer should be removed first, because if it has weak (invisibly delaminated) connection with the panel, it will nullify the effect of any new CLD layers on top of it. However I have not yet found an easy way to remove that dreaded factory bitumen crap.

[@actionjackson1971]

@@NihadH I would've needed a few extra days to try to remove the factory deadening alone. I applied the CLD over it, then a layer of CCF for 100% coverage. I have some MLV on order so I may apply that over everything.

[@margincall7]

I just apply CLD all over the OEM CLD. It's not like it's going to cause any problems. As for the 20-30% coverage, I am OCD, so I tend to go for 70% or so, especially on flat areas that are prone to vibrating as opposed to curved ones. CLD is so cheap these days, that even 100% coverage is nothing, really. My concern was why this video showed way less than even 90% coverage of MLV, which is the key aspect of full sound deadening. Even a tiny crack could negate the entire MLV effort.

[@focused313]

Your car better be as quiet as a Bentley after that. I would have liked to see a db measurement test...before and after... Both still and moving, with a mic positioned where a drivers ears might be.

[@CarAudioFabrication]

focused313 I would like to do this in the future as well. Unfortunately right now I do not have the equipment for such a test.

[@PerformanceDrummer]

+CarAudioFabrication this video was great! a lot of other car audio fabrication videos simply just put dynamat everywhere haphazardly. I wanted to see a video with MLV used. Also, if you do future similar videos, there are a bunch of free DB measurement apps for your phone. I use "Sound Meter."

[@margincall7]

It's not possible to compete with luxury cars designed for quiet interior cabins by doing sound deadening stuff like this. A significant amount of exterior noise is avoided by luxury cars through specific acoustic glass and various glass thicknesses, dampening of the suspension parts where they connect to the chassis, aerodynamics designed to stop wind noise at the source, and other things of this nature.

[@JebsonofJeb]

If i decided to take this to a shop how much would it cost to get the front and back floors (where you put your feet) covered?

[@j4kethegreat91]

If I do this could I get rid of the stock foam that's under the carpet? I'm ok the same step as this video right now, I have the carpet and seats out and wondering if I could get rid it since it's pretty beat up and nasty from all the backseat spills. Cleaned my carpet a bunch! I appreciate your help man!!

[@CarAudioFabrication]

Jacob Villegas I try to keep as much OEM foam or the "bluish" chopped up fiber mat as possible. I pull the OEM CLD materials since they are an easy replacement. If your foam is massively degrading though due to water damage it might be worth just replacing.

[@Vidal2021]

Jacob Villegas If its not saturated, keep it. If it is you can purchase "automotive insulation/foam" don't use the house version from the hardware store.

[@rowskijohn5509]

just the right time,nice work! I am about to do my floor tomorrow. unfortunately I live in Australia and can't really get a hand on any second skin products(just checked and the shipping will actually cost me nearly two grands). really interested in the luxury liner, wondering if I can achieve a similar result with stp+focal bam combo.

[@SecondSkinAudio]

jazz mad Try out a company called Shipporters, they offer drop shipping for Australian customers via the slow boat method, but our Australian customers use it a lot. www.shipporter.com/

[@mehulmepani]

After all that layering, it will be impossible to refit the ABS plastic parts (like door sills and centre console) and the seats etc, as their tabs will not match the car slots. What is your suggestion for the same?

[@oopsydaisy4637]

Thanks for a really helpful and great video! I have been trying to find a decent video that includes closed cell foam use as well as something like dynamat and silent coat. I am hoping that when it comes me having a go, it will be somewhere near as good as your install.

[@jeffhermida4788]

thanks for the video. this is a lot of work, especially for a novice like me. good to know that this is possible diy project.

[@carlossevillanor]

Great videos ... I'm watching them all little by little. just a question. To avoid rolling noise, is it more important to soundproof the floor, the arches of the wheels and trunk or the doors?

[@kavonjones9015]

CarAudioFab I was making a ice cooler and getting component speakers and i and a few question 1.Will sound deading help with. This application to? 2.6×9s or component for sound and bass 3. Do I foam in the inside like you see in speaker boxes 4.what alternetive sealed battery can i use to power. (car battery is to heavy) Lawn mower? Wheel chair? 5.can you mismatch amp and speaker brand. (do you recommend it) Hope I hear from you soon.

[@Motorsportsgeek]

I used roofing material to stick on the panels, cut up yoga mats over it instead of MLV and a lot of closed cell foam everywhere, what is your opinion on this method ? Honestly it barely costed me 100$ of material and it really made a difference in reducing road noise.

[@tanker9987]

Yoga mats are usually just a thicker CCF, if you want a cheap MLV go find some used conveyor belts or some other source of thick rubber. Roofing seal is usually extremely thin and has hardly any mass to it, so you end up having to buy so much of it to properly dampen vibrations that you would have saved money by just buying the commercial product. Otherwise flooring underlay is an extremely cheap source of CCF. I used to try and get around the "system" like you and save money through alternatives. However I usually ended up paying more and was always doing things twice. Now I just buy the proven products and forget about trying to save the money. Too many hours of my life that I won't be getting back.

[@tomgreen1423]

Dankus Memus EXCELLENT POINT!!!!

[@jaydawg116]

Hey what’s your thoughts on different brands of sound deadening? And is there a whole lot of difference in between more rigid aluminum and less rigid on sound deadening backing?

[@margincall7]

From my research: CLD: should be relatively heavy and have some beefiness to it. I have been using XXX Rattle Trap by Fat Mat and it does the job just fine. CCF: I can't call out specific thickness or weight/lb. The CEF layer is pretty ambiguous, but I use 1/4" thickness on my car with good results. MLV: typically needs to be 1lb/sqft in mass for optimum efficiency. I have seen 2lb/sqft stuff as well, but I haven't seen it in applications. Other than these technical specs, who cares about brand? Just get the best deal by sq ft, IMHO.

[@1famentertainment271]

Hello, I looking to make a custom speaker box for my new chrystler 200 2015. Its all white with a custom black stripe down the middle. I was looking to Mame a unique box design to flow with the trunk as well. I was hoping maybe you could help. I have 2 12subs and a 10 speaker I wanted to use but I could just stick to the 2 12subs.. What do you recommend and on design as well. Thx

[@mpjcv]

You did not take out the original sound deadening of the car. Would it cause rust?

[@chuyuribe8405]

Hey mark I've seen all the ways you sound deaden the floor, which is the best way?

[@puneet7891]

Would adding this or something like Dynamat lined up in my trunk cut down exhaust drone? I understand exhaust drone cannot be completely removed with sound deadener/dampner material, but it would be nice to turn the volume down on the drone in my car with my exhaust system. Just to make it more tolerable.

[@tanker9987]

From experience, no. Sound deadening is great for reducing road noise and improving stereo quality, however exhaust drone is simply too loud and bounces off the environment and back into your cabin through the windows. The only way is to use either a J-pipe or install a second muffler (inline).

[@Vidal2021]

Good video, but I have to add/correct you slightly. The CCF can be used as you have stated, but it primary purpose is for separating your dampened panel and the MLV. You need to install a layer of CCF to separate your dampened panels from your MLV. Your installation will allow any resonation, of your panels, to be passed through the MLV. You can increase the effectiveness of the install by separating the two with the CCF.

I read a Amazon review. It said, OverKill Cell Foam smell was unbearable at 10 feet away. I cannot imagine the smell in your cabin on the hot summer day. Had a very strong burning rubber or asphalt smell to it. So what was your take on the smell and did it ever go away?

[@CarAudioFabrication]

You must of misunderstood the review or whoever typed it must not have known what they were talking about, I have never once had an issue with any smell whatsoever.

[@ThreeDrink3849]

Thank you for that fast response. Good to hear.

Mark, I have a bunch of second skin sound deadening but I was wondering if I use a spray on sound deadening and the second skin, will the second skin stick to the spray on. Just wanted a double wall sound deadening.

[@gargpuneet88]

can we add a layer of closed cell foam over MLV? Will it insulate more sound?

[@CarAudioInc]

Not so much, but it might decouple whatever rests on those layers, (wires, plastic pieces, etc)

[@mechanicalmanny494]

How heavy is the car now

[@Valdarious]

How heavy is some of this material, like for a normal mid sized car how much weight would all this add?

[@CarAudioFabrication]

It adds substantial weight, maybe 50-100 pounds, in the grand scheme of things not a big deal though. If you are running a track car then don't put it in.
