i already deaden my doors so they are good. the problem is the door panel is making some rattle sound. it bothers me. i am an*l retentive when it comes to car audio so every little thing bothers me.
now my idea is applying dynamat to the inside of the door panel.
i've done it. friend had me do it for his car, came out really nice. went cheap with edead v1, almost 2 layers on the door and then 1 layer on the inside of the panel. really helped.
not only did it help sound wise, but it also makes it damn near impossible for the wind to blow the door open hard. gives it a really nice heavy thud when you close it
