bro, now my car only one side got the metal knocking vibrating sound when the bass it loud, can i solve this problem with the Insudamp that u selling?

huh, that means i need to buy both InsuDamp and Flex Mat?
or juz choose either one?
u confirm it can solve the problem? wat if i am using the plastic windows regulator? hard to stick because the surface is not flat like those metal regulator.

u mean 1 box of insudamp equals the size of 4 flexmat?
how much is the price? thicker means more effective and better is it?
