Awesome job man and thanks a bunch for all the updates and pictures!!! It'll help alot of peeps here!!

Quick questions: Did you happen to tackle the roof panel as well??

Overall do you believe its a big night and day difference with everything you've done?? Noticeable Reduction in Noise

Started sound deadening the interior. Want a quieter ride and hopefully helps on the sound quality of the stereo system. Using the stuff from Amazon. Considerably cheaper than Dynamat and the like . It goes down the same, doesn’t smell. Topping with a foam layer.

Did you do the lift hatch as well? How did you pop off the cover for the lock hatch?

Hey @Vincenzo what are your db readings at idle and at 70mph currently? Also, what tires are you running? In my SR5 using the Niosh app on my iphone I am reading approximately 49db at idle and around 70db at 70mph. I am running Kenda RT 33x10.5r17.

At idle I’m getting right at 40. At 50, idling in gear. I will get some numbers at 70. There are factors to consider there. Tires and condition of asphalt.

Try driving a Bronco or a Wrangler then go to this. It'll be the quietest vehicle you ever drove

I have done the SoundSkins deadening on my doors (inner, outer, and foam layers) and it made a tremendous difference. I spoke with the company yesterday and they plan to have a precut kit for the rear hatch sometime next month. I kept some extra material for that project.

Any moisture/water concern behind the doors? They had that moisture/vapor barrier behind the doors coming from the factory also drain hole at bottom of all the doors. Wouldn't all these sound deadening material soak up moisture over time?

The drain holes are still accessible and only the rear doors have a thin plastic sheet vapor barrier, which is replaced with the soundskins material. The front doors have a vapor panel, which is reinstalled. The soundskins material is advertised as waterproof so I don't see an issue with your concerns.

When you had the back hatch area apart, did you find a location for the rear hatch alarm speaker? The one that beeps a warning every time you open and close the rear hatch?

Curious, how did cutting a hole in the carpet for the amp quiet the engine noise? Was the carpet lifted up by the amp or something...

Likely for better amp cooling. Those are heat sink fins on top of the amp to radiate heat. Covering it with carpet traps heat.

Cutting the carpet has nothing to do with engine noise. Amplifiers get hot. It makes absolutely no sense to me why they buried it under carpet.
