Auto sound - Which damping material should I use ?

[pm]

Hi, I want to put some damping material in the doors of my car.
I would like to use something that not only dampens the backwave and resonances/reflections of the driver but also reduces road noise.
Would the multi-layer Sonic Barrier stuff be ideal for this purpose ?
Thanks!

Percy, another option you could check into is Cascade Audio Engineering. They have many products, from the sheet materials to spray/brush on compounds. Go to <A HREF="http://www.cascadeaudio.com">www.cascadeaudio.com</A> and you'll be able to see all the stuff...it's less expensive than other similar products and performs better. Great bunch of guys to work with, and if you have any specific ?'s, you could call them...Doug or Linkin would be able to help. Good luck!
