Fellow readers, I have terrible vibration issues that are robbing my system of midbass and bass from my door JL speakers due to wild vibrations coming from the front doors. They vibrate and resonate like crazy. And rattling of course. I do have generous amounts of dynamat in the doors, but the holes are not covered nor is there any material stuffed in the doors (particularly up high by the window). What are some of the best ways to control these resonance issues that doesn't involve metal fabrication of a garage full of tools??? I know my system can sound wildly better. I just need to be the only thing that's rattling around the car. I have a 1997 Nissan Maxima.

You can put some ccf between the door panel and the metal of the door. Wrap ccf around the door lock rods.

Are your midbass speakers mounted to the door panel or the metal door
CCF? Does that stand for closed cell foam or something like that? Is there a specific kind to get? Does it get rid of moisture effectively since it will undoubtedly get wet inside the door. What about sealing all the holes? Or do you stuff it with so much "CCF" that it effectively seals them? Assume I know nothing about this (pretty close to the truth), and provide details as if to a child ;)

I'm not sure what the maxima doors look like, but I found that a sheet of MLV between the inner door skin and the door card (panel) effectively seals the entire door at one time and is quite easy to do for the beginner. I outlined how to do this in the following thread, about half way down the first page.

That looks promising. One other question though. I have heard (and felt) that the air space at the very top of the door (where your elbow would rest if the window were open in other words) is obviously a terribly hollow and resonant space. What is the best way to fill that? I also get terrible rattling right by the very top back part of the driver side front door. Ideas for that? It doesn't seem like the MLV would address that specifically. And where do you get your MLV?

Thanks!!!
