Final verdict is that this is a must have goodie for people looking to really enjoy their music, a little expensive but a must have.
The box reads that Dyanamt is 10 times more effective than copy mats, and i think that is completely true.
I havent got quite a lot of time to listen to my music in depth, because i got too tired and my fingers started to hurt, more importantly it is Bakra time, so had to take care of them.
Anyway for as much ive listened, i could clearly tell you that Dynamat is 100 times more effective than underlay, it enhances your listening experience to quite a great extent, it stops rattles, and my car definitely feels quite silent now.
The midbass response has increased tremendously, no boominess at all now, precise and tight bass.
Im still left with one sheet and a couple of pieces of this awesome thing, which i would use on the rear shelf and maybe on the innerside of the plastic door poshish, although ive got underlay there, but still if there be a need, id use Dynamat there too.
Thanks for enjoying the show, i hope you have a great festive Bakra Eid tomorrow, and enjoy with your family.
Stay safe. Eid Mubarik!
