Sound Deadener - Dynamat?

[MarshRam]

It seems most everyone is choosing Dynamat. Do the other brands that are much cheaper, such as Kilmat and Noico really not get the job done?

I don't know what your budget or sound quality you seek, Marsh. Having done a complete Dynamat (mat, liner, pad), I can tell you it is a pain in the ass to rip out the seats, the carpet, part of the dash, A/B/C pillars, the headliner and carrier plates on the doors. If you ABSOLUTELY want to make sure you've done it right, use Dynamat. I have never once heard anyone regret using it. Are there other decent products? Without a doubt, but mileage varies. Good luck on the project. No matter what you end up using it will be a big improvement over stock!

I did the entire interior of my SRT using RAAMAT from RAAMAUDIO.

It was considerably cheaper, it layed out nice, was easy to work with and, after 9 years, it's still soft and pliable doing the job it was intended to do. That was my only concern in that it might break down or harden over time.

Just don't use anything that is asphalt based. You will regret it when it gets hot and that stuff starts falling off. Make sure butyl based is what you get. Dynamat, Stinger Roadkill, Second Skin, sds, nvx. All good stuff. The cheap stuff, I wouldn't use personally. You get what you pay for. If you do it right and get the good stuff to begin with, you won't have ruined parts with gooey asphalt ruining your interior.

Hey guys, thanks, this was all the info I was looking for. The tip on the heat is great, Im in FL so that is important. I already have a complete aftermarket system, but I do not like how you can hear the muffled music + slight rattle coming through the doors. Not sure if I am going to do a full install, but those doors must get done and I think that will also make that mid base hit much cleaner. Considering how much work it will be, I think I may just go with the trusted dynamat or other higher end deadener. Much appreciated!

I watch a lot of 5 star car stereo, they are based in Florida as well

Think they use Roadkill Ultimant, A butal product with a additional 1/8" of foam

They seem to be raving about it

I have a couple threads on my Dynamat build and video links to tearing down the carrier plate and headliner in the DIY section. Hope they help ya.

I remember reading that and will be taking another peak at it. Very helpful, thanks!

I used raamaudio as well. It works great. It will stay put Just do ur research. The "dynamat" and like products only add weight to a panel to keep it from resonating. Don't waste ur money on 100%coverage either. It's just not needed.

Thanks, I am going to take a look at raamaudio. I really do not think I need a full install, but those doors are no doubt in need. Full install will probably only happen if I get bored, which is possible! Lol...

It gets addicting. Once you get an area covered, and turn the sound on, seeing it improve, it lulls you into doing more and more. When I started my Dynamat journey on a previous vehicle, I was going to do "just the doors," and I have been an addict ever since.

 

[MarshRam]

Yeah, I know the drill!!! It gets even harder to resist when you think you are close to the finish line. I haven't built a surfboard in months. That's what I'm supposed to be doing with my free time, NOT fixing up my truck and lurking around on the Ram Forum. Lol....

 

[bigdodge]

Those doors r the worst for sure. I can't believe they didn't add anything to them. I just had enough to add 2 sheets to 3 doors. To knock on the one with and without is pretty extreme. I really am going to be working on the road noise. I think it can have a really quit cab.

You can get there. It is ridiculously quiet in my truck now.

So, I have seen a couple comments already in the various dynamat threads where people are saying there is no need to line the entire door. However, I searched the net to get an understanding of where in the door I should be placing it if not covering the entire door and I cant find anything. Everyone is lining the entire door panel.

I don't have too much of an issue with the sound in the cab as far as rattle goes. What really bothers me is when the music is up and you can hear slight rattle and the music itself from the outside.

I have MT tires, a light bar and roof racks. Needless to say, my truck is loud, so I play the music like Im in the front row of a concert to drown everything out most the time. I don't care to have the car next to me at the stop light listening to muffled music coming out my doors. I'm not concerned about passing on a little bass vibration, that just cant be stopped.

I understand my interior sound will improve, which is great, but my primary objective is to cut out the noise filtering outside. Seems it would make sense to line the entire door. But, nobody is really talking about the sound from the exterior. Will lining the doors give me the solution I am looking for?

turn the music down at stop lights so the car next to you does not hear your music if it is a concern to you. That's a cheap fix.
Regarding noise filtering outside in general...dampener does nothing for airborne frequencies inside or outside. Dampener simply adds weight to panels to reduce resonances/ vibrations. Technically, it reduces buzzing or eliminates it altogether which is great...but dampener does not block sound. There is a huge difference between sound deadening and sound proofing when it comes to materials used. CCF & MLV with proper decoupling is what reduces airborne frequencies to a degree. You will have more time & money invested in "sound proofing" then you would replacing your mud terrains with something that doesn't howl as much. Sucks, but you can't have your cake and eat it too.
You're not finding a bunch of info regarding sound from the exterior because the volume knob is within reach.

He is absolutely right. All the work put into ccf, mlv, and deadner is so u can have an excellent experience INSIDE. Best thing to do if the rattling outside concerns u is play it loud and crawl around the truck and try to isolate certain panels causing the noise. There is no manual that will tell u exactly how it's done.

Thanks guys, thats what I figured. Not really into playing with my volume knob at every stoplight and I'll just live with it. My last Ram stock radio automatically reduced volume when I came to a stop, not sure if they have something like that for aftermarket radios. Anyway, if I start this project I guess it will have to be all about cleaning up sound on the inside. Thanks again for your replies!

 

[S0CAL]

Marsh, not knowing what materials you are using, I can only talk about my experience when I had your dilemma. I took off my door carrier plates and lined every inch of the entire panel with dynamat. I then lined the carrier plate itself in the largest areas also with dynamat (to kill some of the buzz), I then covered the inside of the door panel in dynamat completely, followed up with 1/4 in dynaliner. I did this on all 4 doors. On the back wall, I substituted 1/2 inch, as well as the floor, and on the roof 1/8 inch dynaliner. I then used dynapad (non-adhesive, 1 lb/sq ft sound deadener/heat resistant pad) on the floor all the way up to the firewall. I have a 4" lift, 35" tires, LT headers, a full exhaust system and a very good audio system . With the radio off, I hear just a good hum when I gas it, otherwise mostly windshear and no roadhum from my Nitto TG2s. No rattles, no smell, no noise. Music is chamber-like.

It cost a ****-ton, I get that (Lord knows I heard it from my wife when I did it). But it is simply amazing, and quieter than my wife's 2015 Lexus sedan.

It really comes down to time and money. It is a pain in the ass to do the full installation, but I will do it again in my next truck, without question. For me, it's worth every penny I spent, every bottle of beer I consumed, and every explicative I uttered.

Like I said earlier, anything is an improvement over stock. And as someone else said, leave the tar-based roofing material to the home improvement DIYs.

 

[MarshRam]

Thanks Socal. With everything said, it makes sense for me to go full install. Less worried about costs, more concerned about time. It's my daily driver and if I do the whole truck, thats not happening in one weekend!! I'll be tearing down and putting back together way too much to get a full install done.

My tires really aren't that much if an issue. But, the light bar and roof racks together, especially on a windy day which we get a lot of, thats a symphony of its own...I'm sure lining the roof can help, but I can hear these things through the windshield, lol...

I'm getting ready to hit 90k and its bugging me, thats usually when I off my vehicles, but I'm too far invested and I like what Ive done so far. Time to get me a little honda so I'm not slapping all these miles on this thing and can take more time with my mods. Think I'm going to put this project on hold until I find me that car.
