i have taken apart most of the interiors of the cars i own , and it's fairly strait forward, i did see a couple of you tube videos from a couple called 1Five1 Garage, they break theirs down in various videos, and it's a great reference!
Should be quiet AF
This weekend i decided to tackle the higher than used to road noise levels on our 2 door. After gutting the interior i am surprised that other than the carpet there is nothing to help keep outside noise at bay.
Taking the interior apart was fairly easy and took under 2 hours to get it done, after a good cleaning of all the panels it was time to lay some killmat down followed by some silex foam, and some sound absorbing felt material on the plastic panels and wheel well cavity. The rear wheels line up pretty close to your ears on the 2 door, i was surprised that there is nothing there to help with the road and tire noise. All the panel clips were lines with tesa tape before reinstalling. I still have the doors to get done(ran out of material) ,but even now the drop in road noise is very noticeable, and the bronco feels more solid.
As long as we had the interior apart we also replaced some of the speakers, the B&O is lacking and the Infinity speakers made it sound much much better.
Overall a good rainy weekend project
..but it seems to me that different tires and roads could skew the readings considerably.
The killmat keeps the metal from flexing, or sounding like a tin can. The foam helps block some of the sound, and insulates the cabin and decouples the panels from the metal making helping with sound transferring. The felt i added in some spots helps absorb sound as well. I bad as this car is insulated i figured it could use all the help i could give it.
What i did definitely helps, are there better products out there... oh yeah!! But at a substantially higher cost. Mas dampend vinyl can also be used, but it adds about 1b per sq ft used and it's a pain to work with.
Are you using a special type of felt or would felt carpet padding work? Also what kind of adhesive for the felt? Your answers are appreciated. First time through this.
Plenty of room inside the drivers side wheel well, a little less on the passenger due to the factory sub
Roberts 70-190A 70-190 Super Felt... https://www.amazon.com/dp/B0049VIQCK?ref=ppx_pop_mob_ap_share is what i used. I've used it for years as have friends of mine, it's inexpensive and works pretty good. On some applications like the rear bulkhead of my raptor i have mulitple layers of it. Only way to make it tolerable inside. 6.2 l supercharged 700hp motor with stainless headers and a race muffler about 12 inches long, dumping out the side before the rear wheels.
