Sound deadening materials recommendation!

[240sxworkinprogress]

What type of sound deadening materials would you all recommend for just a daily driver. I don't care about the weight factory. I've been looking at Fatmat, Dynamat, b-quiet, second skin and a few others. I found a web site (www.sounddeadenershowdown.com) that gives some info on different types of sound material but even the writer says that it not that scientific of a study. He recommends Second skin as being the best quality. I been looking at Fatmat because there cheap and I can get a hundred feet for 120 dollars. On the other hand I don’t really want shit that doesn’t work well. Also about how much do you all think I’ll need? I don’t plan on double layering the material unless I have to. I’m not going for a show car just something a little quieter than what I have now. So what brand would you all recommend for my car?

[nissanguy13]

It kind of sounds like a rhetorical question due to the fact you researched it and found a chart that compared all of them buy quality and price. Also if you are worried about pricing and want to go for the cheapest one, then it sounds like you are more worried about price than quality.

You get what you pay for. You want to play you must pay.

[240sxworkinprogress]

No I just want to get the most bang for the buck. I searched on zilvia and somebody sayed they like Fatmat. It just so happen to be the cheapest. I can get 80 ft of the second skin for 187 which isn't to bad if it will be enough to do the car.

[kandyflip445]

Fatmat works ok. They took forever to ship and I had a hassle with them. Probably would go with another brand just because of that.

[240sxworkinprogress]

Also the web site was going for sound competition quality and he was pricing the material to do the car at about 500 to 600 dollars for 300 ft of material. I’m hoping that it not going to take that much material.

How many feet did you need to do the car?

[nissanguy13]

damn thats a lot. A 100 ft roll would probably do your car and then some

[GSXRJJordan]

100 ft^2 should do you just fine. That's enough for at least a layer for the trunk, floor, and doors.

I used Dynamat Extreme on my S13 (not the whole car, just the trouble spots - trunk, doors, wheel wells) because I had a few rolls left over from when I worked at Best Buy. It worked well, never came off.

For my S14, I'm planning on using the liquid eDead from Elemental Designs. They sell them in gallon buckets, for $50, and I'll probably need two for the whole car. This is for a completely gutted chassis, going for least weight added and also for a nice look (black, painted eDead looks better than aluminum with a Dynamat logo, since I have no carpet). I'm hoping it'll be durable enough to last - I may also do some standard 'roll on' in the doors, because I happen to be a SQ nut and will probably install my very decent SQ system in the S14.

[kandyflip445]

100ft^2 works. I did my trunk with 3 layers and most of the floorboard. The doors and had a lot left over. Still haven't got around to taking out the dash and doing that area yet though.

Remember to use as big of pieces as you can to get the best effect. Don't slap a lot of small pieces on.

I'll have to look into the reflectix material. It kinda looks like silver bubble wrap. Is that the material your talking about?

[mifesto]

i am also planning on adding sound deadening to the rear section (rear passenger and trunk area) and was going to go with Damplifier Pro

Uh, no. That stuff is probably the worst possible material you can use. Sure, it'll work somewhat, but it's nowhere near good enough to work on automotive applications. Really, the biggest problem with stuff is that it has a relatively high failure rate over time due to the heat and vibrations encountered in automotive applications.

Also, if you're really serious about sound deadening you should be aware that true sound deadening is a modular system that includes painted on sound deadener/heat absorber, dynamat-type insulation sheets, and foam. Depending on what you're aiming for you can get away with using only one of those products, while using all three of those applications is aimed at audiophiles and people that want as little noise as possible.

As was said earlier, you gotta pay to play. While there are certainly products out there that are cheaper and offer a better value compared to similar products from other manufacturers, when it comes down to it, real automotive sound deadening falls into the same category as any other automotive upgrade. That is to say, you get what you pay for.

Good luck!

Don't use stuff from hardware stores. I've seen people that used those and it ended up ruining interior pieces when it got hot. Not good at all.

Yea I've learned from buying cheap stuff before, it usually bits you in the a**. I'm not really going for crazy sound deaden. I just want something a little quieter than what I have now for trips. I think I might pay the little extra and get the second skin stuff. The guy that did the review on the different types of material recommends the stuff highly. Have any of you all use there product before?

[4thHorse]

RaamMat from raamAudio is what I used and it is great. I doubled up on the doors, did the rear quarter panals and the whole trunk. Then I covered it all up with insolite which is sold on their site for pretty cheap. I have step by step install that I'll post up, but it will take around 24hrs. (I'm at work camara is at home)

Yea that stuff doesn't look to bad. I could get 2 roles for about a 200 dollars. Did you just order the material from the company directly or through a dealer ?

[4thHorse]

I ordered everything from their site. 2 rolls of the rammat, 3 cans of glue, and I think 4 yards of the ensolite. I used 1 roll on my 96 240, the other roll is for my buddies 350z. It's great, you knock on the areas I matted and you just get this thud. Also this adds around 20lbs to the car, but it is spread out.

Sorry for no pix was running late for work.

Raamat is great..order direct.

I went with SecondSkin Damplifer (their cheaper product). I don't have a major system...just wanted to get rid of some of the resonance and noise.

Once I used most of two shipments of Damplifier my car was as quiet gutted (no interior panels, rear seats, trunk stuff, carpet) as it was fully assembled. It was really different re-assembled, my doors shut nice and quiet except with the windows all the way down they still rattled a little. I was told I can solve that with closed cell foam, but it was expensive for what I needed to order.

I got the Damplifier cheap on a website called sounddomain.com

Yea that about what I want to do, just get rid of some noises. I tryed going to Sounddomain.com and didn't see any place to get the Damplifer cheaper. Did you get the material from a dealer on the forum?

Most of the dampener guys are on their ...I think his is SecondSkin

the other guy is RAAMsomething...

Both are excellent products and both dudes are great at customer service.

[krazydriver]

I rock bedliner and no sound deadening in my car. definately not what you want.

In my friends car we used dynamat, we got a good hook up on the price from a local audio shop and it works well.

[JFoxx]

with the brands you listed there isnt a big difference in quality. just try to get some with a thicker mm. some of the off brands can be 1/2 as thick, thus u have to use twice as much. i used fatmat in my old car and it worked great. USE A HEAT GUN TO APPLY!

[EDacIouSX]

i dont know, sound deadening in a 240 defeats the purpose doesnt it? I mean, if you want luxury you buy a luxury car. 240s aren't really meant in my opinion to be all comfortable and luxury status. at least not enough to sound deaden a sports car

Yea I agree that 240sx weren't designed for luxury but they also weren't designed to half the stuff people do to them. I'm just trying to make it a little more enjoyable for long trips. I want to be able to listen to the radio with our hearing the road noise and if I can fix the problem pretty easily then why not.

[4thHorse]

I thought the final few years of the S14 240sx were sold as entry level luxury sport cars, with the 200sx being their sport coupe that competed with the Integra. Maybe just in my area, I remember seeing 240sx sticker prices for 25k and this is back in 98.

You might be right I don't know for sure. But when I think of luxury sport cars, I think of BMW M3, Mercedes AMG and so one. I guess when your comparing a 240sx to an Integra then they could be classified as entry level sports cars as long as they are still stock. When you start adding aftermarket part usually you have to pick between comfort or performance.

[GSXRJJordan]

It doesn't fucking matter what it was marketed as, or even built as. When you've got a car stripped down to the bare chassis, they're all the same.

The sound deadening is something that is definitely worth a look, unless your car is strictly a competition car. I've got my S14 down to bare chassis in most of it, and am watching every pound I put back into it, but will still put about $100 and 50lbs or so into sound deadening - just because a little bit goes a lonnnnng way when you remove the factory tar stuff.

If you find that driving your car is 'fatiguing', or you feel like your stereo should sound better, or you want to be able to talk on the phone with the windows up on the freeway, you can probably use some sound deadening - no matter what car.

Depends how much money you throw at it. At even higher street levels, you can have comfort and performance (of course within limits)...for cheap it's not that hard to make a great handling 240sx if you have decent roads.
