Dynamat Options

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

Selective application of sound deadening mat will help the doors sound more solid/less tinny.

I’m debating how much of the interior metal firewall to cover with sound mat, leaning towards all of it.

Trying typing “914world.com sound deadening” into good and look at the image results, lots of ideas there as noted above.

Biggest difference for me was adding several 75mm wide strips inside the doors,added thin material over the floors and that made little difference,I also put under hood sound deadener on to the rear of the backpad of which a small improvement was noticed.
Real hard to tame the noise from a "6" ,going back to stock air cleaner from K&N's made a huge difference however.
