Flashburn, do you still have the pictures from your original post? If so, I would be interested in seeing how your install progressed.

So far, I covered approximately 75% of the hatch with B-Quiet Ultimate. I also fit 2 sheets of Second Skin Luxury Liner Pro (LLP) in the hatch, which covers 90% of the surface area. I also worked in some B-Quiet and LLP in the cubby behind the drivers seat.

The car is still very loud, but haven't had a chance to secure all of the material properly or reinstall my interior. Unfortunately, I also managed to bang up the wiring of my 4-channel amp during the install, so I can't comment on improvement to audio quality yet.

Next steps: Work on the door panels and the floor (if I have enough material) and reinstall the interior. I'm considering ordering the Second Skin Spectrum to spray in the wheel wells and hatch, but I'm hoping that I wont need to do that.
