I'd say just make sure to have even coverage everywhere, curves, corners etc. If you have a small roller that can def help not only speed the process up but will also make sure the material hits/sticks better to the metal/plastic or wherever you decide to deaden. If you run a hardtop at all, think about deadening both the back of the hardtop and freedom top panels and then covering the material with some kind of headliner kit, Mopar/Hotheads etc.

I just went through and deadened under the carpet front to back and the hardtop and covered with the Mopar headliner kit and it's a great change in road noise, interior resonation and the stereo def liked it!

 

Might take a look at this video just to see if there is anything that will help you.

Pretty disappointed that there was no video to say whether or not it made any difference at all.

 

I just did this a few months ago. Used boom mat material on my two door. I removed the back seat and all of the carpet. Did not remove the front seats. The results were amazing. The toughest part was getting the carpet back in! The poster who advised to get a roller was spot on. For the adhesive material to work you need to clean all surfaces and use a roller to make good contact. I would wear gloves when cutting the material. I didn't and had little cuts all over my hand afterwards. While I immediately noticed the difference when I applied the material to the tub, I didn't notice much difference with the hard top. I cut strips to apply to the top then used mopar headliners. Not much difference but the top does look better.

 

Do you need to completely cover the floor or can you space the sound deadener apart and still achieve a quieter ride?

 

You probably can and I did, but on my 2 door I did the entire floor and it was noticeably quieter than my 4 door Recon that I spaced them out on. The only real difference is I covered the entire floor on my 2 door and I ran KO2's as opposed to the Ridge Grapplers that I'm running now. I do feel the RG's are louder than the KO2's so that might be the issue. I will be probably switching back to the KO2's s I may be able to compare better.

 

I did this recently and here is a post from around Thanksgiving.

The best $375 spent on my Jeep in quite a while
Bought from Amazon Mopar Headliners $235

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Stinger RKXDK Roadkill Expert Series Sound Damping Material Door Kit $42

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Stinger RKX36B Roadkill Expert Series Sound Damping Material Bulk Pack $95

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1


With this I was able to sound dampen under the headliners, the complete floor, rear wheel arches and all 4 doors. I did the installation myself in 3 about 3 hour stages. The foor and headliner was a piece of cake. The doors were more of a challenge, but youtube had a video which made much easier than if I had ti figure everything out myself.

From the forum I had upgraded the speakers in the sound bar, tweeter fix and a new subwoofer. This was done a few years ago and made quite an improvement over the stock kit.

Now it is night and day different, sounds way better!! And the Jeep is just quiet now. We must remember it's a Jeep and that will never change no matter what we do, but such an improvement I wish I had done it years ago.

I'm in CA so weather extremes are not a problem but now in the morning it warms up and stays comfortable.

I have all my mods listed in my garage under my sig. if anyone is interested in the audio upgrades, I think all done they were around $150. The system now sounds like a high-end unit and the drivers' environment is much nicer.

Just my .02 cents if it helps anyone.

 

Don't forget behind the door panels as well.
I did a layer of Ensolite on top of the Raammat and it helps with noise.
Buy a roller....

 

This. The doors on a JK are super thin, so don't cut corners and do these.

I doubt you would notice the extra weight.

Boom mat weights 0.3768lb/ft^2
80mil Noico weights 0.77lb/ft^2
Fatmat weights 0.45lb/ft^2

I added just over 3 square feet of 80mil Noico to each of my doors, approximately 2.3lbs (about 2 20oz bottles of water)

don't forget the original... Dynamat. It's also 0.45lb/ft^2

 

You didn't mention specifically what type of product you are thinking of using. If you are thinking about Lizard Skin, I would highly recommend it. I chose it over the dynamat types just because I wanted something that looks better after application. I have used it extensively on my total rebuild. Everything from doing the inside and outside of a bare tub off the frame to the inside of the top and panels, doors, fender wells, etc. It's very easy to use. Easy to apply and water cleanup. Tape things off well and easy application with the gun and air supply. The ceramic coating and sound barrier don't have after smell at all. However, the aerosol top coat does. Its not terrible but very noticeable. Be prepared to live with that while it off gasses.

If you decide to do the top and panels, make sure you do not use the sound barrier and ceramic coating on the overlapping parts of the top and panels or under the rotating latches. I did on the first one and its a tight fit so the panels were a little too snug. I sanded it off and just used the top coat on those areas and its much better.

Mine won’t be as pro as yours. Just using Noico 80 (similar to dynamat for a lot less) I already have Mopar headliner front to back and sides of the side back windows.

 

I had my hard top and panels Rhino lined and it makes a huge difference with the noise form my roof rack. I will be going to bed tread sometime in the not so distant future which may help even more.

 

Start My Sound Deading

I just finished the Freedom Panels using the Noico 80, I did a somewhat sloppy job as this was my first time working with stuff. I did round off the last corner after I took this photo. I haven't started the Hardtop yet as I'm still debating weather to cover the area's completely or just put Noico strips in the channels. I'll be using Noico under the carpet, but not completely covering the floor. Last step will be to get Mopar or HH head liners. I'm not trying to make it into a Cadillac, just make it more bearable for those longer highway trips and hopefully improve the stereo.

How many sq. ft. Of Noico did you use? 2 door Or 4?

 

Any updates from folks that used Noico on their hardtop? Definitely interested in doing this and then using the MOPAR headliners on top.

 

I did the whole top in it. It helped, but the Jeep isn’t a daily and I have pretty far for that, which is very quiet. A project for me in the near future is to do the whole Jeep. I’m going to do the noico dynamat stuff and then another layer of the foam stuff. As I focus on it, the doors and firewall are the big culprits that I can hear...

 

What about when it rains and you have the top off? All the carpet gets wet but dries up quickly, at least mine does. Will that sound deadener survive?

 

Thats why you only use hydroscopic materials, closed cell foam, butyl rubber etc....

 

I went with HotHead. Did the complete kit with sound assassin and around the back window in the HT. So far I’m very pleased. Changed the tone for sure and a bit less noise.

 

I just did this last week. I went with Noico 80. Deadened the sound greatly. It felt weird driving at first. Kinda like a sound studio room. I did not do the top or doors. I was surprised how much difference it made just doing the floor.

 

Did you do the wheel wells?

 

I can see myself doing this but not going to remove seats. Will remove carpet. I see there are several types. I keep my back seat folded down and some thick carpet on top for the dogs to lay on so it's already somewhat quiet. Can any of these be used as a headliner alone? Thinking the foot well area of the floors and the rear fender area should really make a difference without making it a huge project. The product videos show it doesn't have to cover 100% to quiet things.

 

If your jeep in new/clean , crawl under and apply the aluminum covered stuff on the exposed sheetmetal, and under the hood.

 

So I just did the driver’s door. Obviously not driving much, and have to wait for the rest of the stuff to get here, but it wasn’t near as hard as I thought it would be.

 

My goal when applying was to make sure I rolled it enough not to see any diamond pattern. That way I knew it should be stuck down enough to not allow water or moisture to prevent premature rusting.

 

Has anyone seen or used this product? It looks like it would be a great option for the floor. It is a floor covering and sound deadening all built into 1.

I kind of like the idea of this vs. trying to leave the carpet in. Just wipe it down and drain it out, while providing sound deadening and heat shielding.

 

I’ve not done the floor yet.

I did finish the doors today and went for a drive. Wow!!! With only the doors, a dramatic difference. I can hear where the wheel wells in the rear are making a huge amount of noise and the engine too. So I suspect when the insulation comes in, it will make a massive difference and be as quiet as my S4 or my wife’s Range Rover.

Bottom line, I’d highly recommend this for someone using a JK as a daily Driver who would like it a good bit quieter. One this aside from being quieter is that the stereo sounds WAY better as well. Remember this is just the doors I did and just layer of deadener. I can’t wait to take the interior apart and do the floor.

The nice part is the doors take less than an hour each. Get proper plastic trim pry tools and BE CAREFUL when you get the windows off he track as all that’s stuff is plastic and can break easily I’d think. Replacing a window regulator would I bet be expensive and a PITA to replace.

 

Is there a Decibel App for one of your phones? Be kinda cool is someone did a before and after test run. Help me decide if this is value added for me! I guess someone else could find it helpful too?

 

There are and I wanted to do it that was initially, but just didn’t take the time. There are a million videos out there doing it and a lot of data supporting it. I too was skeptical, and wasn’t sure based on what used to be high cost and then the effort to effectually take the interior of the car apart to do it.

Now that there are cheaper alternatives to Dynamat and a lot more data to include the science behind what it does and how to apply products, it seemed like a good move. Then when you take into account the interior of a Wrangler really isn’t too hard to disassemble, it seemed worth it to do my own science project to see. Obviously now based on my initial findings of the doors, it definitely will be worth it. Keep in mind this will end up adding probably 100 lbs to the machine when you do. These aren’t sports cars, and I’ve already added a few hundred pounds in winch, bumper, and armor underneath, so whatever.

 

Haha, was just saying yesterday how I wish I had taken before and after pix of a clean up project my father left for me. But I didn't take the time either. I've never really even looked into the cost of lining the Jeep. I picked up a '19 Ram CTD around Thanksgiving and pretty much every nickel has gone to it. Side steps, mud flaps, 35s, wheels not to mention the cost of entry. I did get a daystar hood latch kit for the JK a few weeks ago. Maybe this winter when its parked I'll tear it apart and give the sound baffles a go. The new Ram is so quiet compared to the JK. I feel like I'm at a rock concert in the Jeep now.

 

So I finished up the effort yesterday and went for a drive today at freeway speed. ABSOLUTELY worth it. It was windy going through a canyon too.

it’s not as quiet as either of our very nice daily drivers (it is still a Jeep after all), but will make it much nicer for freeway driving. I get more tire noise, and of course wind noise is still there, but it is certainly more comfortable at higher speeds. I can hear more creaks and squeaks as well. I probably could make it quieter still, but it would make nominal difference I’d think. The biggest difference is the stereo. It sounds WAY better at all speeds and you don’t need to turn it up as loud to hear everything now as well.

Bottom line, very much worth it It’s not that hard to take the interior apart (aside from needing the impact gun for the rear seat), and the stuff lays down pretty simple. Some cutting here and there, but even with the foam, not much more effort in getting it all back together.

 

How much weight do you figure you added? Am I gonna need air bags or move up to a 3.5" lift to keep my 2.5" lift stance?
Nice job by the way. Thanks for posting.

 

I’d say it added around 50 or so lbs if I add what I put in the hard top too. The foam weighs nothing, but the sound deadening is really dense. I went for another drive today and the difference from opening the windows to them being closed is nuts. It’s like a normal passenger car at up to 50mph, and then it’s just nice at freeway speeds.

I can’t say much about weight as I just added a 120 or so lbs of rear bumper too, so my days of having a spritely Jeep are over.

 

If you want a good intro into sound deadening Cascade Audio Engineering is a good place to start. This is not a sales pitch though there stuff is really good, it is about the different types of materials to use based on the noise you are trying to eliminate.

For the Jeep I used SoundSkins Pro. Great product, easy to use and it reduces vibrations, loss of sound and improve heat rejection.

 

I researched this heavily a few years ago for a different toy car and saw that brand. Even though the Jeep is a toy, it is still a Jeep that is used like one. The goal was just to quiet it down for the times I do long freeway drones a bit and not spend a mint or months trying to figure out what to do next to turn it into a Rolls. For my needs/expectations, mission accomplished, but I definitely know there are better and more complete solutions.

As stated above, there is a cost/benefit to going overboard as it relates to weight and such. When I looked into it before, it was going to be for a car that I tracked, where weight is important, so it's always a toss up. Hopefully I achieved a decent balance...
