The TX highway department seems to love a cheap noisy overcoat for asphalt roads that was driving me crazy, so I decided to rip out the back of the car and do some soundproofing:
To do this I watched the youtube video:
I took out the rear seat backs (4 nuts) so that I could completely take out the liner which wraps under the seat backs. It really was not that hard to take it all out. I just took time to note where I got each of the fasteners from so I could put it back later.
As you can see in the pictures, Tesla does put some sound dampening material around the inside. They also have some padding on the back of the liners which looks like it would help dampen noise:
I got some dynamat: https://www.amazon.com/gp/product/B00020CB2S/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
and a dynapad: https://www.amazon.com/gp/product/B001KM5IZO/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
I proceeded to use 7 of the 9 sheets in the package. I decided to save a couple of sheets for the front if I ever get around to it.
The first three sheets I applied to the driver's side wheel. Note you can reach quite a ways around the wheel. Tesla had some material on the inside, I did it behind:
Then I took out the sub woofer and amplifier assembly on the passenger side. I did not disconnect the wiring:
I only used 2 sheets on the passenger side since I did not want to apply it around the sub woofer. I was afraid it could dampen the sound of the woofer. Looks like I hit a forum picture limit and will have to add another message to continue!
