Really want to start making the truck quieter. I'm going to have to do this in chunks because;
1) I don't have a ton of extra cash right now
2) I don't have the time to really completely pull the truck apart and do the whole interior in one shot

Where do I start? If I can only do one section at a time where do I start? Where does most of the noise come from?
I already have the factory roof liner in the truck and did a tint of the front windows.

most of the noise is going to be wind and road noise. buy a box of Dynamat xtreme, place it on the larger panels in the truck. floor/firewall/inside the door skins

you can get the DynaPad to go under the carpet in the foot wells. its basically a rubber pad, not sticky like dynamat

I can tell you from experience a Jeep and sound deadening is an uphill battle. you will make progress, but it will be slow.

when the time comes for tires, stay away from Mud Terrains, and do not put an aftermarket exhaust on the truck, especially an offroad shorty type that dumps out under the cab

I've got some gun case foam padding laying around. I was thinking of sticking it up between the sunshade and the freedom top, Will that do anything or a waste of time?

Check the adjustment on your latches on hardtop, there are posts here where guys adjusted them and made a huge difference, also tires and age of tires is very important,I am running factory Falken Wildpeak AT3 all terrains, and at around 30,000 miles at least twice as loud. Search for windshield noise , here lot of guys are adding foam under cowls and folding windshield front and adding foam.
I hate to say it but it is a Jeep, sort of why I wonder about guys putting great radios in them and running huge mudder tires, but as long as they are happy it’s all good….Jack

You know, I tried to figure out ways to make the inside quieter when I was on the highway during a long drive. The noise isn't bad around town, or if I'm hopping on the interstate for half an hour or less, but it definitely would get to me anything over that. I looked at a lot of options, and I realized that the easiest and cheapest way I could do it is to just use a pair of wireless earbuds with noise cancelling. It's worked great honestly, and a decent, comfortable pair is way cheaper and easier than going through with buying and installing all the sound deadening materials.

In my JK, i eventually went to a Rugged Radios intercom kit. Best $ i've spent for road trips. phone plugged into aux for music, and i my passenger can hear when i talk to them

Unfortunately, outside noise in the cab while driving is all part of the charm and the sacrifice of this design. It sounds like you already have a headliner. You can Dynamat/Kilmat the entire inside of the doors, floor and roof. Lots of experiments tried and discussed on this forum with mixed results. Is it worth the time and $$ to pursue it? ?‍♂

A lot of the noise comes from the top hard edge of the windshield to freedom panels. It's not easy to get rid of. Someone on here used weather seal around the inside of the windshield while it was folded down to get rid of some of the sound as air enters there. Once you fold down your windshield you'll see what I'm talking about.

I found that the headliners help to absorb interior sounds by reducing the echo the plastic top promotes. I have the Hothead headliners. I don't think it's reducing too much of the exterior decibels you hear but like I said they definitely reduce the interior sound bouncing around. Sort of like you'd experience in a recording studio, (if you've ever done that).

I placed 80 mil butyl sound proofing mat on the bottom of the cab. I took the seats and carpet out.

I also added the same stuff on the panels (under the headliner).

This made a big improvement. I’m very happy with it.

To further improve noise, sound deadener can be added to the back of the cab and the doors. I don’t plan on going to this extent.

I already have the factory roof liner in the truck and did a tint of the front windows.
I pulled the seats, folded the carpet up around the center console and Killmat the floor- pulled the door panels, and the stupid pita inner panels and Killmat the entire door skin, picked up some hothead liners- Killmat’ed the areas under the head liner. Folded down the front windshield and added 1/4” rubber weather stripping insulation stuff- Home Depot… to the front windshield where it makes contact/has a slight gap when up….
Worked amazingly well….

^^^ all this and people will say “it’s a Jeep”!!!! Yeah, well now it’s a quiet one. ?. Y’all keep doing your duck and angry grill thing, I’ll keep quiet in my quiet diesel…. ????


Material wise it took 2 boxes of 80mi 36sqft Killmat. $100 on Amazon. Photo shows Killmat with 4mm siliss liner over parts of the Killmat…. Pretty sure the Killmat did 90% of the deadening…
Also recommend “NORSMIC Car Sound Deadening Roller (2PCS, Width: 1.69in & 0.24in)”.

The doors, and the roof in the back are the two “biggest” bleeds to noise…. The back roof is a trip once you do this.

I pulled the sub And sound deadened behind it- big “audio” change… (wasn’t expecting- doing it for this… just an effect/observation)

Do you know of a YouTube video that shows how to remove the stuff at the back of the cab? I’m rather, umm, impatient sometimes, and I don’t want to break anything.

I think it definitely is, Jeep skimped on the sound insulation because they can. While I completely understand and accept the noise will never be completely gone, I have a navigator that does not. And keeping her happy keeps her in the side seat and not making me drive a perpetual yawn with stupidly narrow seats that are even less comfortable than mine. ('17 Cherokee)

A lot of the noise comes from the top hard edge of the windshield to freedom panels. It's not easy to get rid of. Someone on here used weather seal around the inside of the windshield while it was folded down to get rid of some of the sound as air enters there.

I hadn't seen that hack, hmmm. Gonna have to have an upgrade weekend I think.

I pulled the seats, folded the carpet up around the center console and Killmat the floor- pulled the door panels, and the stupid pita inner panels and Killmat the entire door skin, picked up some hothead liners- Killmat’ed the areas under the head liner. Folded down the front windshield and added 1/4” rubber weather stripping insulation stuff- Home Depot… to the front windshield where it makes contact/has a slight gap when up….

Jeeps can be quieter, and totally worth it.
The doors, and the roof in the back are the two “biggest” bleeds to noise…. The back roof is a trip once you do this.

OK, so what I'm getting is the first places to sound proof are the:

Windshield surround- weather stipping behind windshield. I should maybe find a way to deal with the lightbar noise.
Roof panels- more sound matting on the roof
Floor- Starting with rear floor and cab wall. It does make sense that the area between cab and bed would be an echo chamber.
