Sound Deadening

The one thing I haven't like about my Fit is the road noise. It has always been quite noisy driving on the freeway having just installed a new stereo I decided it was time to do some sound deadening as well.

I came across GTMAT Automotive Sound Deadener Dampening Dynamat/Fatmat Alternative I have never been more pleased with a purchase in my life. I put in 10sqft in my trunk and heard a very noticeable difference in road noise.

Here is a picture of my trunk:



And here is a picture of my hatch door (still in progress):

No, none at all. The material is rather light and being so thin and spread out across the vehicle I wouldn't expect to see much of a difference. I checked earlier today and I'm getting >38MPG on the freeway and I tend to stay around 28-31 in the city.

Starting with the trunk because that's where I started.

Step 1: Remove the spare tire
Step 2: Vacuum any loose debris
Step 3: Spray a degreasing agent and wipe it off (I used engine degreaser)
Step 4: Measure twice
Step 5: Cut once
Step 6: Peel the backing off and stick it down
Step 7: Use the roller and make sure its down good
Step 8: Use a hair dryer or heat gun and go over it
Step 9: Make sure its in there good

Removing the Hatch Panel

Step 1: Start with removing the handle to close it (pops out with a couple of clips)
Step 2: Remove the square thing near the latch
Step 3: The following picture shows where the clips are use some tools to pry off the panel



I used
these these
tools.

This process can be a little frustrating, but take your time and try to do it on a warmer day so that the plastic isn't too brittle from cold temperatures.

Got a picture of the Driver's door today and put the panel back on before I got a picture of the completed door. Will get one up soon.

I did something similar using a U-Seal roof flashing from Home Depot, it worked wonders in the doors and inner sheet metal panels. My doors feel like it has a bit more heft to it but it shuts with a very solid and quiet thud like a Lexus door. It dropped my interior noise just a tad, i find it was a cheap upgrade. I also lined the door panels with a thin foam strip to reduce leaking sounds and rattles from the door panels. I also installed additional weatherstrip along the open doom seams (like Lexus does it) to reduce wind noise.

I found them a bit harder to get them back on properly. But since I didn't they are lots easier getting off and back on.
