What did you do with your 60 this weekend? (3 Viewers)

[WartHog73]

Finished this out. The sound deadening is definitely worth it. My door rubber seals are now whats making the most noise inside the truck... along with the whine from my transfer case adapter. Its way quieter in here now.

Trans tunnel is a little lumpy on the carpet because I put down butyl, foam, MLV, and kept the jute in place for the most sound deadening i could possibly get. I still need to put the sound deadening into the 4 doors, but already did the cargo panel areas. This is an absurdly rough job but i was able to knock it all out in 2.5 days and its a noticeable decrease in noise inside of the truck.

Looks beautiful. I used the exact same stuff on my 60 a couple years ago, and it made a significant difference - can have normal volume conversations now. Also used the damplifier on the doors and when they close now they sound solid. For a couple days, I just opened and closed my doors for fun lol. I'm a simple man...

I wish I had doubled up on the MLV for the transmission hump area and may go back and do that again. If you have any left over and you think you can squeeze it in, would rec doing so. Although if I had an LS like you I may want to just listen to the sound and smile...

Carpeted liners? do you mean the Jute on the fabric? Or the carpeted wheel wells? If youre talking about the carpeted wheel wells, i tried to use those but my razor slipped when cutting one and i ruined it. Im kinda devastated becasue i REALLY wanted to use them and you cant just order the wheel wells. you have to order the whole kit to get them.

These arent the best pics, but i stopped the MLV right before the floor slopes down for where the trough is to run the wires by the pinch welds. I kinda sacrificed some sound deadening in that area but i have a lot of wires in those areas between the aux power i have running to the back of the truck, speaker wires, etc.

I filled in the large gaps after this pic was taken

Alright, I need to do this. What did you use and in what order did you lay down the material? Did you also remove the factory sound deadening?

Second skin damplifier pro -> second skin luxury liner pro -> @dnp carpet kit. Some remove the jute from the carpet before install. I kept mine. And I left my factory sound deadening in there. Just pulled out the old carpet and cleaned out all of the old stuck on jute and went to town

Haha so ironically my LS is quieter than my 2f was . I do wish I doubled up mine too but I’m not sure if I could get it to fit under the carpet. Can always go back and try again though. I still need to do my doors. I have some Amazon stock on butyl in a box that I was going to use. Similar product to the damplifier pro I used for the floor, but the foil isn’t as nice and the sticky stuff is slightly thinner.

My wife thinks I’m crazy out here knocking the side of my rear quarter panels so I’m right there with you hah

I did the same after mine, I would knock on all the body panels walking around the vehicle

Did you use the 1lb or 2lb luxury liner? And how much did you need?

 

[lacalvette]

Finishing my first arb air locker install (re-using gear). Wasn't impress with the air copper pipe hanging over the crown, so I made bracket and I decrease the amount of play on the seal house (back and forth). I'm wondering about removing almost all play. Any toughts ? Heat, dilatation...

 

[lacalvette]

And, just an idea for testing the air locker no $ spent, I used (temporary) a fitting included in the box, a flex (1/4) with hose clamp. Work great.

I didnt know there was multiple options to be honest. I used this one

Luxury Liner Pro™ MLV + Foam Auto Sound Barrier Sheets

Get the best mass loaded vinyl and heat insulation barrier for your car. When used with Second Skin Audio sound deadening, any car can be a luxury vehicle.

www.secondskinaudio.com

I used 54 sq ft or 6 sheets and had just enough to do all of it. I used the cut off scraps for a lot of the curves like the wheel wells.

For the Damplifier Pro stick on stuff I used 31 sheets but ran out and had to use 1 or 2 sheets of the amazon sound deadener i had on hand. Thats just for the floors and cargo panel areas, doors not included

Been half-following along on your sound deadening quest. What's the purpose of using two different products? I checked the Second Skin website on both and there isn't much specific reading material about what each product does or doesn't do. From working in recording studios for decades, I generally understand what MLV and closed cell foam do, but for this specific application, I'm not sure. Is the MLV used more to damped steel panels from vibrating like a drum head, and the closed cell foam is more to limit sound transmission through matter?

Ah I was just looking at the Luxury Liner MLV, not the pro. The pros $$$. Wonder if there’s much a difference between the two, haven’t read into it yet.

The MLV is a closed cell foam on top of a rubberized sheet, and then there's butyl backed foil as well. There's a noticeable difference in the metal panels that I have and have not covered in the butyl backed products. I used it years ago to remove vibrations from a subwoofer setup.

This is my first time using the MLV along with the butyl/foil but my truck wasn't loud to begin with. A decibel reading app on my phone had my 60 series around 65 decibels at highway speed. I never felt the need to raise my voice during conversation. I was able to get away with using 6 sheets so I've got two entire sheets leftover.

the pro is a 2 in one, its got the closed cell foam bonded to the MLV. that way you only have to do 2 layers of sound deadening instead of 3. Saves many hours haha

so the butyl stuff (damplifier pro) is used to literally absorb the the vibrations and resonant sound waves travelling through the sheet metal of your truck. This vibrational noise is from like wind, bumps, rain, etc. Think of hitting a high hat with a drum stick with it open. Then close the high hat really tight with your foot and hit it again. The metal isnt able to ring out as much because it is unable to vibrate as much. So all the vibrations and structural noise get dampened by the stick on stuff because it doesnt allow it to freely vibrate. (or in your specific case.... open string strum vs palm muting haha).

The closed cell foam layer is an absorption layer that supposedly absorbs airborne sound waves and slows them down so some of the energy gets transferred to heat. , but mostly filters out higher frequencies.

The Mass loaded vinyl is what does most of the airborne sound wave blocking. Its a heavy and blocks airborne sound waves. It cant be installed directly to the sheet metal due to resonance and needs some kind of air barrier, and thats what the closed cell foam is for.

so in short, the stick on stuff is to stop vibrations, the closed cell foam is to decouple the MLV from the floor and to slow down air vibrations, and the MLV is to block the sounds in general. You also get insulation properties from each layer so your AC and heat work better and it holds temps better

Im no expert on this at all, this is just what ive found in my research before doing this project.


Found a video where they stick it on a crash cymbal

That all makes perfect sense and is mostly what I figured. I’ve done some amateur room treatments for a long time, and both my wife and I are drummers (among other things), so you’re speaking my language.

Side note: I bet the lowest absorbed frequency of the MLV can be varied by the thickness of the material between it and the sheet metal. I bet if you have 1/4”-3/8” gap you’re absorbing down to around 1000Hz. Completely shooting from the hip here, I haven’t done the math. In order to absorb very low frequency stuff that gap grows to the point that it’s ridiculous - all that has to fit under the carpet after all. But yes mass loaded vinyl does a great job … and is not cheap.

 

[costahh]

Finally got around to the 4x4 labs rear bumper unfortunately wasn’t as hands on as dbbowen and had a friend to most of the leg work but saw some bad frame rust that’ll need immediate attention always something to chase, did get in a stainless steel battery tray as my current one is mostly rust

I always figured y’all for the guitar haha. The second skin company makes a ton of room sound deadening stuff too. I’d bet there’s a good market for those giant sprinter vans people live for that stuff. Could use a mix of automotive and home stuff for that

Dang man! That looks great! I need to finish that thread. Waiting on some parts to finish out the arms section haha

Probably not worth posting, but we have a little dog that likes to ride on the console. Since the lid is hard plastic the dog would slide off. Installed some rubber sheeting and the dog is much happier!

Where's you get that sheeting? Looks like a prime candidate for putting on the bottom of my replacement glove box to lessen rattling/movement of stuff inside.

Any sort of tray/shelf liner would work
