Dynamat: What thickness should you use? should you put over the tar on the floor should you throw away the rubber pad behind the backpad on the firewall?
I need some adivce: I want to add sound barrier under my backpad and possibly floor. I currently have the black tar floor, nothing in doors and rubber pad behind backpad which honestly has seen better days and looks pretty nasty. Should I add any sound proofing to the floor before I carpet? If so, what thickness? Also, should I throw out the old cracked and dirty rubber pad and put sound proofing on top of the firewall behind the backpad or leave it as is? Thanks in advance for advice |

Dynamat must be applied to sheet metal.
Putting it over OEM tar on floor or the existing back pad will have no effect. There are two thickness of Dynamat. If you look at the test specs on line - you’ll see that the effectiveness is proportional to the mass and thickness of the mat. I’d recommend the thicker Dynamat unless you’re really trying to save weight. |
