Sound deadening??

**ICRAZY6** · 10-08-2010, 10:55 AM

I love how my car sounds with everything it has done to it, but you have to yell to have a conversation while driving. Just curious to see what people are doing to deaden the sound in the cabin of the car.

full dynomat treatment will help. Doing the hatch area will help as well if you have aftermarket exhaust and it exits out the back.

**ICRAZY6** · 10-08-2010, 12:21 PM

It exits out the back. Checked into dynomat but it's pretty costly. Anyone else?

**35th-ANV-SS** · 10-08-2010, 12:33 PM

I was going to mention Dynomat also. It is probably the best and most proven sound deadening there is. It's been around a long time.

**JaycenK** · 10-08-2010, 05:16 PM

there are cheaper but they suck if you try to do any top, or side mount installs(falls off). Spend the money and get a big sheet of it and do your spare tire area and the t top area all the way up the back to where the latch is and see if that helps. You could do that area for about 75 to 100 bucks I think if you plan it out right it may go a bit further. I have LT with off roar Y and an slp loud mouth so I know what your talking about lol. Try stuffing a huge bed spreed in the T top area and see if it helps. I have been meaning to try this to see how much it cuts down the noise. It should be close to dynomat. Sheet metal is thin back there and single layer (no pockets).

I used a simlar product to dynamat called b-quite Utimate, its even thicker than dynamat and far cheaper. For about $250 you can get 2 rolls of 50sq feet and do the complete interior of your car, floor, hatch, sides, doors and probably have some left over. If you only get 1 roll you will be sorry. It is heavier than Dynamat but I'm not one of those who is so concerned about weight.

there are several ways to dampen the car. it all depends on how far you wanna take it. dynomat is effective, and the other versions as well. there are several sprays that you can mix yourself from a 5 gallon bucket, and it works quite well. im not talking about aresol cans. this stuff is water mixable and it can be shot with a paint gun. works great on places dynomat wont stay or go.. if your interested, hit me up and ill give you an idea of what your looking at price wise and how to go about it. i reccomend matting the areas the guys listed below, then spraying the hard to reach areas. the more you spray the more it deadens, and its super lightweight.

Another product that my dad and I are using on his toys and eventually on my 'Bird is LizardSkin. It's a spray on product that you only have to lay on 1mm thick on the inside and/or outside. Supposed to be easy to apply, I'll let you know once we get that far!

this is what i was going to say. you can apply up to 3 coats if wanted. it comes with a special spry gun that kinda spits out the paint/ compound. i want to try it.

A friend of my dad used it on his 20-something street rod and loved it. We've stripped the interior out and are replacing the floor in my dad's 55 and are going to coat the inside and underneath of the floor before we set the body back on the frame. Looked at doing the 'Bird when I redo the interior next summer (hopefully, if I don't have to replace the transmission!)

It maybe expensive but it is worth it. I have on evey wall of my truck including doors except the roof don't have it up there. But it quites down road nosie and all so will make your sound system sound better and if you have a sub woofer it will make it hit harder.

Wait till your rear end has got a foot in the door. Then we can talk cabin noise, lol.

As mentioned before, Dynamat is the most popular for a reason. They've been around for ever b/c they work the best. When I used to do alot installing, it was the only way to go.

However, I am very interested to see how these spray in ones work, b/c there has been so many times Dynamat was beotch install or nearly impossible. With it being cheaper and would probably take 1/4 of the time to do, this would be a great alternative.

KMdef9 Not sure what you mean by "Wait till your rear end has got a foot in the door. Then we can talk cabin noise."

Anyways, car has been put in storage and will start on the project in the spring.

The stuff I have seen used comes in a spray can and just sprays on like spray paint (much thicker though) and when it dries it becomes like a "rubber" material. People who do body work and paint cars use it.

**ICRAZY6** · 11-05-2010, 10:46 AM

Lizard Skin is probably what I'll use.

My rear is on it's way out, it whines so loud I have to yell at the passenger for them to hear me when above 50mph. I forget the technical terms.

Does it end up looking like a spray in liner? Or smoother than that?

If your rear end is makeing that much noise. I would tear it down and fix it before it busts on you then you will be out a lot more money. Its warning u right now to fix me or I going to lay down on u. If it does you can look at about $1000 dollers worth of parts if u do it right possi and good gears and axels. But if u tear it down now you might get away with just bearings and new ring gear and pion. I waited to late for my diff and had to replace everything in it. I did do the work my self but if u don't have some one who knows how to set up your ring gear and pion it will make noise with new stuff in there and won't last long. My dad helped me we pulled my rear end compltely out because we could not get the rod out of the diff messed up bad. Got it done love my eaton and new richmond gears and superior axels. I have a stout 10 bolt. One day may have to a bigger rear end but untill I throw this one out I am not scared of any power that I can put trough it.

i put dynamat in the entire rear hatch area, took 20sqft and made a HUGE difference, a lot less road noise and the speakers sound better

If I remember right (has been a while), once it dries it is like a spray in liner or a little "bumpy".
