It definitely helps with the road noise but watch out if you're using Luxury Liner Pro as it's very thick. The back panels don't quite fit right anymore and it's hard to line up those plastic tabs back in the holes. Also I have the bose system and I couldn't get the sub to screw back into place because the LLP was too thick. It doesn't rattle around or anything but I figure I need to secure it better eventually.
I got mine to a decent fit but I'll need to go back and really look at how things fit and maybe redo where I placed the LLP. I would recommend at most 2 sheets of LLP for the hatch, but probably 1 would do the job without bulking everything up.
