How To: Sound Deadening, doors and floor

If you are into improving the quality of your sound system as well as reducing noise and vibration, a sound deadening material is something you should absolutely look into. Most products come in sheets that are peel and stick, making installation incredibly easy.

The product that I chose to go with is Dynamat extreme, a .067" sound deadening material that came in a pack of nine 18"x32" sheets.

The kit comes with dynamat tape, a roller, and some nifty stickers.

The first area I applied the dynamat to was the inside of the doors.
1. Remove the cover inside the handle and the arm rest to access two screws you need to remove

2. Using a flat head screwdriver, pry out the bottom of the door skin, it should pop right out, then you can lift up and remove it
3. Disconnect all electrical connectors, as well as the cables for the latch and lock, leaving you with a bare door

4. Make sure the window is rolled up, I made the mistake of leaving mine down, it has to be all the way up for access to the inner door.
5. Peel away the plastic to gain access to the inner door
6. Take some measurements and start applying the dynamat. Recommended effective coverage is 30% of the area applied to. Since I had a lot of material, I covered as much as I could

7. Its difficult to see, but the dynamat goes all the way to the edges of the inside of the door, and to the bottom as well
8. Repeat this process for the rest of the doors, the rears are very similar, just different shape

9. I did just the inside of the doors because I wanted to make sure I had enough material for the floor, which I was doing at a later date. After just doing the doors, I noticed a huge difference in the clarity and quality of my sound system was incredible.

Floors

1. The most difficult thing about doing the floors is getting everything out of the way. I spent three times as much time taking out seats and moving carpet as I did actually applying the dynamat.
2. First things first, the seats front and rear need to come out. theres 4 14mm bolts for each front seat and 4 14mm bolts for the rear seats.

3. Once the seats are out, take the trim pieces off the edge and peel up the carpet

4. Once you can move the carpet up and out of the way, you have access to the floor and you can start applying the dynamat. I again went for max coverage instead of just 30%, and it was incredibly easy to apply with all the space

5. Once you have everything applied, its just a matter of reinstalling everything and putting the interior back together. You can notice an immediate difference just in the way panels sound if you tap on them vs ones that don't have any dynamat.


After using this product and seeing the results it provided, I can see myself doing this to every vehicle I have from here on out. It has made a miraculous difference in both vibration and road noise as well as the quality of my audio. All in all a very effective and simple modification, with no real downside

 

Been looking for this write up. Thanks!

 

I see you have a amp under the seat... Hows the fitment? Do you have measurement of it? I want to put one in.

 

fitment is perfect, i didnt measure before putting it in because originally i was gonna put it in a different spot but it fits perfectly under the seat.
