Is dyna mat worth it?

JCar

I did what you are thinking of on mine. It helped somewhat, but it wasn't worth the time or money imo. If I had kept the car I would've gone a different route this summer. I do believe that it would've made a bigger difference on the doors. After looking into options I think that a filler like a thick carpet pad type material would work better for the rear. It would fill the spaces where the dynamat was just an added layer.

I'm not saying that there isn't an improvement with just the dynamat, but it wasn't enough for me.
