Sound Deadening

Close to half the vibration damping/noise mitigation threads on other forums are debates about using asphalt based materials as a vibration damper. I’ve spent way too much time during the last 5 years typing and re-typing responses to these questions. Let’s keep it in one place to reduce litter and redundancy. This topic was my introduction to aftermarket “sound deadening”. I had a noisy car, wanted to quiet it down and started to do research. This was 2005. Several respected “authorities” were vocal advocates for asphalt. Part of this came from the belief that products like Dynamat Xtreme were part of a conspiracy to fleece consumers. Part of it was the often repeated “f…

Hey, I sent an email around octoberish about deadening my 08 scion xb but never received a reply. I don't know if the email got lost or what. I rechecked the address and it was the same as what everyone says to reach you at. If there is a better way to contact you about sds products just let me know. Hope to hear from you as these xcons are doing some work on my car.

I spoke with Don of SDS and we thought this would be a nice addition. As we have a dedicated Sound Deadening section here, this topic is meant for technical questions you want to ask Don directly to help add to the resource of this section. No, this is not a topic about SDS product pricing and such, that is what Don's email is for. Hopefully this will be a nice focused discussion to help people understand the concepts and purpose behind different materials and products available.

I was wondering how much deadner i would need for my truck and what is some good deadner for the $$$my budget is about 300 buck's...i wanna do the roof and the back door...

I want to completely deaden the inside of my vehicle with SSD's CLD, CCF, and MLV. Vehicle is a 2-door Jeep Wrangler 04' hardtop, the interior of a jeep has less plastic trim than most other vehicles... from the floor to the window line is sheet metal covered in a layer of carpet.... Will that make any difference in the approach I should take? The door panels have been glassed on the bottom to house 2 6.5's and a tweeter, and there is about 3/4" gap between the sheet metal and the inside of the door panel. I think 3/4" will be enough to get a layer of CLD, CCF, and MLV in there? One of my concerns is if I will be able to install the MLV and CCF on the ceiling, I don't wa…

anyone layer up their roof ? and how many layers thick ??

I have a 08 Impala and when I had my Icon 12 on a 1200D, the bumper rattled like crazy. I had two layers of Raamat on the trunk outer skin. It seems like there is a piece of plastic or something smacking the frame behind the bumper and causing most of the rattle. Just wondering if anyone has fixed this issue. I have an Xcon 15 coming and it will be on 2000w~ and I know it will be a little worse. Any help is appreciated.

Whats up???? has anyone heard of audio barrier? If so is the stuff any good cause its soo much cheaper than the other dampening companies out there. if you have any info id like to know thanks.

is it any good and what is it comparable too?

i thought i heard about some on here recently? like 119 for i forgot how much, but it was alot....help!?

Just in case no one has seen, Don over at SDS is having a sale as of 10/20/2013.

Just bought my firdt classic car. 1966 Cadillac DeVille drop top. Have 1 jl w7 in trunk and she rattles like crazy. This is a classic worth money so I dont want to f anything up but need to get rid of the rsttles asap. Is there one that is somewhat easily removable that wint ruin the paint. If I ever sell, another collector wont buy with this installed. Appreciate the advice and opinions!

The side windows in a bronco's top are only held in by rubber trim, Unfortunately they are not tight enough to withstand the pressures of bass. The windows flex back and forth and on some songs can make enough noise to be annoying. Anyone have any ideas on how to better secure them? I was thinking maybe epoxy of some sort, but I'm not sure if it would work or which one to use.

Hey all, i just bought a shop pack of damplifier pro 80ft, hoping it will be well worth it since it cost me around 540$ for the pack (shipping/us-cad). I just wanted to know if i should deaden the whole car which would require prob another 80ft and im also thinking of ordering a pack of mlv/ccf. I will be running around 1200rms, and the car is a lexus so it is pretty quiet from start. What do u guys think? Im thinkin if i need another 80ft will jus go with regular damplifer instead of the pro to save some $. Also, getting it installed is another huge cost. Theres this shop that i know do an amazing job 100% of the time but they are charging around 1000$. Another shop whi…

Was up, Ive been here a bunch of times and just now am I starting to post, This forum has changed and I like it, vs when I originally signed up..I mainly hung out on the OG PG Phorum, DIYaudo,Diyma,sd etc under the same user name of Freshkryp69, Ive sold tons of amps on ebay but haven't in awhile (sick of paypals shit).. I Had another kid in 07 my beautiful daughter and I put everything on the back burner audio wise, but kept most of my equipment for that one day, now my kids are 19 & 6 in school full time so now I have time to play again! In my noob days I thought I was the shit for figuring out that the $15 roll of asphalt based Peel-n-Sea…

Getting terrible rattles coming from a stock spoiler in a 2008 Grand Prix. What's the recommended treatment here? My first thought is taking it off and drilling a small hole to shoot expanding foam in. Unsure how the expanding foam really works and if it has any negatives.

i got a khaotic enclosure and i was going to put it in my trunk, but it wouldnt fit, so now im putting it in the back passenger side seat. the box is vertical with the port above the front passenger's head rest. i took the passenger rear seat out, and im putting a wood barrier where the seat back used to be. not sure what kind of wood to use tho. then im mounting my 4 channel amp to the back of the wood barrier. was going to put MLVB on the barrier and then closed cell foam on top. then some more closed cell foam on the bottom of the seat where there is just metal now, so the box wont vibrate against it. so am i going the right way with this sound deadening? and also what…

I'm going to be firing my subs and port forward and sealing off the trunk from the cabin. So far, I only have my front doors and trunk lid deadened. I only bought 36 sq ft of dynamat extreme (I live 5 minutes from the factory, gotta support them haha), what should I deaden primarily first? Because I'm sealing off from the trunk, do I even need to deaden anything in the trunk?

Okay so im gonna be running four Sundown Audio SA-8's on a SAZ2000d. Im working on building a fiberglass box for them in my Silverado and I have heard some stuff about deadening the interior of the enclosure to gain spl and sq as well. Is this true? If so what kinds of deadener would you recomend? im guessing spray but any suggestions are helpful thanks.

I'm about to sound deaden my 1998 gmc jimmy. Has anyone every used the product b-queit ultimate? Also how much should i use. I've heard that only 25% coverage works perfect. I'm not going for insane spl numbers i simply want to stop rattles, and make it sound better on the highway? Any suggestions on better products around the same price? How much to use??

Is he still around? I sent him an email over a week ago and haven't heard back from him yet.

Hello, I have a 2007 Mazda 3 with stock everything. Have yet to make a change but I'm planning on it in the future. My main problem is when i turn up the volume, my door panels rattle around a lot. This is one thing I hate about the car. The doors feel really light and cheap. Anyways, this is a stock system, no subwoofer, bass on h/u is on 0 but when i turn up the volume the speakers cause my door panels to rattle. What type of application would help stop all of this rattling? Do I just need to roll on some deadener on the door? Do I need to remount my speakers outside of the door panel? Just need a little advice to make this rattling stop. Thanks.
