Vibrating panels

[Boom_box]

I got a Nissan Pathfinder and my panel on the backdoor vibrates like hell each time the bass hits. i tried sound dampening it, i tried dyno mat, sound spray and even putting an extra layer of foam but it still vibrates. You can't hear it from the inside but when i bump my system all the people arround notice the panel coz it is on the outside of the car. what do you think i should do?
