Sound Deadener?

[tdstover 10+ year member]

Okay i got 36" Mud Grapplers on my ride, and hearing the tires is really annoying. So im looking to buy some Sound Deadening Material. Will this Material also improve my sound quality?

I was looking at this web site (http://www.b-quiet.com/) Are they good?

I was also reading the different types, Damper, Absorber, Barrier, and Composite, which would be best to get? I really just want to improve my sound quality the most.

Your gonna have to do some wheel well treatments. If it was me this is what I would do.

1 good layer of mat, a couple coats of liquid deadener, and I would top it off with a bedliner finsh. Especially if you like to play.

Second Skin would be my suggestion as far as liquid deadeners.

SecondSkin is the best you can buy - so good choice. It will make your car quieter - making your music sound better. So yes.

Someone more knowledgeable on deadener will fill you in on exactly where for best results - the more the better though.

Being that I've installed a lot of deadner and am under the impression that even if they sold it for double the price any kind of deadner would still be worth it......I'll put my 2 cents in.

Your best case scenario would be to do 3 things:

1. Secure your wheel-wells with a liquid deadner. Mat would require HIGH maintenance and upkeep because it would be applied upside down in the wheel-well. Because, in this case, Mat would be applied on the outer shell of the vehicle, you would have heat in the summer and cold in the winter causing negative affects on the tar based (or butyl) backing. Simply put causing it to constantly fall off especially if the Mat were layered on top of its self. Mat is heavier then you expect. This step alone will not solve your road noise problem nor will you gain any SQ out of your audio.

2. Secure the insides of all four doors. In this case use your Mat. The level of sound deadening will vary on how much you apply. The more the better, don't be afraid to pile it on. This step will ensure you substantial gain in door speaker output and clarity and a low to moderate decrease in road noise.

3. Secure your floor with Mat (Temporarily removing factory seats and carpet to apply). In this case floors can't handle many layers of Mat due to re-fitting factory carpet and such. Decide on a thicker than the normal type of mat. An example would be too apply a Dynamat Extreme compared to a Dynamat Original. If your are able to fit more than one layer of Mat on the floor, then by all means do so due to the fact that this step will reduce more road noise then step 2. This step will also allow for improved SQ inside the cabin.

ALL THREE steps put together will allow you a quiter ride. Unfortunately you will more than likely continue to hear some form of muffled road noise considering that these are 36" mud tires.

As far as improved SQ is concerned. Due to the fact that we are talking about a vehicle with a rather large cabin space, more Mat will be needed. Although steps 2 and 3 will improve your SQ and stop rattles, layers of Mat underneath the roof liner and back hatch are just as important when installing a complete audio system (Aftermarket speakers and subwoofers).

Look at eBay for different types of Mat as it can get expensive quickly.

Hope this helps.

Yes applying it will help out your sound. I have a mix of FatMat and Secondskin and has helped improved my sound. I only have 1 layer and is just in the trunk. I have a long way to go, but will be worth it in the end.

Also I believe some memeber by the name Buffalo something had a nice write up about applying liquid deadener to your inner wheel wells. He mentioned how much it cut back on tire/road noise. This however IIRC was on a regular sedan car. So might not be the same on your 36" tires, lol!

the only two mats worth buying are the second skin damplifier and dynamat extreme. Spray stuff is for areas you just can't get to with a mat.

I would hardly say those are the only two worth buying.

RAAMmat would be my first recommendation, and I would certainly qualify it as "worthy" of being purchased. Is it the best deadener you can buy? No, it's not. Is it the best value deadener you can buy? I think so. I liked RAAMmat more than Damplifier, and as far as mat deadeners go it'll probably be the only deadener I use in the future. Why? It's a great value. It's not the best in every regard, or probably even in any single respect, but IMO has the best combination of price and performance/quality. And Rick is a great person to do business with.

To the OP: What is your budget? That's in part going to determine what route you'll need to take in terms of appropriate quantities and applications of the various deadening materials.

With a vehicle like that and tires like those, you are really working against yourself. Wheel wells are an issue, but I'm sure noise is coming in through the floor and doors as well. You are looking at treating most of the car with a vibration damper like Damplifier or Damplifier Pro (if you are going Second Skin) and then lining it completely with a barrier like Luxury Liner. If this thing ever gets muddy, you might want to look at something like Luxury Liner Pro because of the closed cell foam that will stand up to moisture and abuse better.

I wouldn't worry about exterior treatments until you are done inside. It may or may not help.

I have heard all the stories already ... raam mat is good for like floors, but it will eventually fall off of doors and side panels - and don't even think about the roof.

Wow, apparently my post is completely worthless or you like to hack down previous posts (mine) for a post count.

why don't you get better tires...... 35'' bfg mud terrains are pretty **** quiet.

That's interesting, considering I've had it on my doors, trunk sidewalls and interior side panels now for a good few years and it's still sticking like the day I put it on //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif And I don't do shit for prep work either....dust off the panel to remove any surface dirt, but no hardcore degreasing like some people do. (roof installs I can't speak to as I've not tried it personally)

I don't know where you're hearing these "stories", but it doesn't have nearly the failure rate you'd like to portray. Of the forums I frequent, complaints about RAAMmat are few and far between. And they are probably the forums with the highest usage of RAAMmat.

Although, I guess I shouldn't argue too much with a guy who doesn't even know how to calculate the square footage of deadener //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
