To all the audio heads on here - yes I know this may not be the perfect way to sound deaden the truck, but it was my first try and I'm not going for a competition style truck here.
Update on the sound deadening/audio upgrade process. Was able to finish my sound deadening and adding poly fill to the HK sub this weekend. Currently in a heat wave in Boise, ID so it was a struggle.
Materials:
Kilmat 80mil 36sq ft - only used probably 1/2 of the box
Noico 150mil Red Foam 36sq ft - this is a closed cell foam product also used about half the box.
Pulled the HK Sub out and added poly fil to all of the empty space, making sure to leave room for the sub to move. Didn't make a HUGE difference, but sounds more solid all around.
added Kilmat 80mil to the back wall (didn't do a great job getting pictures). This was about half way through, ended up covering 80% of the back wall. I know a lot of guys are starting to put covers on the rear vents....Concerns me a little know the benefits of having that rear air flow. There are flaps if you look closely that only let air out, nothing comes in. After I saw those vents it made me realize I wasn't getting air flow in to the truck from them, so I left them alone and didn't cover them in any way.
Pulled back the carpet and held it in place with some bungee cords. Let me get full access to the floorboard all the way back to the rear seats.
Started adding KilMat to the floor board. 10x easier than the back wall as it doesn't have mounting points and gear in the way.
Covered about 90% of the floor with Kilmat. Note: in the left side of the picture you can see the battery for the eTorque system in case you were curious how big it was.
Went through and added a layer of Noico 150mil Red Foam (Closed Cell Foam). Should help with some thermal transference and I noticed a HUGE change in how much road noise was coming into the cab.
All in all it was about a 3 day project only working a few hours each day. Been so hot here I can only handle the garage early in the day or late at night. All in, I would say it took about 8 hours from the first turn of a wrench to pull the seats out to securing the last bolt. If you are tuned in to your truck and can notice the small noises and pickup the changes in road noise, I HIGHLY recommend doing it. If you think this is the quietest truck ever made, don't waste your time.
Have some more sound deadening material and speakers en route and will be doing the doors next weekend.
