[QUOTE=JARblue;2182932]Don't expect to NOT hear pebbles bouncing up in your wheel well or anything. It seems to be most effective against general road noise vibrating through the tires. Stuff that bounces up underneath the car definitely sounds more muted, though. I only have two short drives with the install so far, so I will have a better idea after a few days. But right now, it is better than I imagined :tup: :tup:
There are before videos, so I'm going to try to do a comparison after video that mimics the before one as close as possible. The videos include an audio (stock, unfortunately) test while parked and a driving test accelerating to and cruising @ 70 mph. I just wish we had more video of varying road surfaces - the road we were on was pretty quiet so I'm not sure how much difference there will be. I used a simple decibel app on my iPhone, so we'll have to use the same method for comparison. I didn't get my hands on a nice SpL meter until this weekend after I was half way done with the install, but I will use it for a final result dB reading even if it doesn't have a before reading to compare.
Also, while I am impressed with the hatch sound now, I think that doing the doors will be even more noticeable since I sit a lot closer to them. I can't say for sure how the overall dB readings would change. I am definitely planning to do the doors, but I'll have to pick up some more GT Mat Onyx. The hatch took all 18 squares that I had.
First of all, Nice Job :tup: Like you, did the hatch and I also did the doors. Biggest difference in doors for me is hearing my speakers better, as I just got reg sound system that comes w/spt pkg.
Washed, clay bar & waxed Z & GTI. Time for a beer :yum:
