Hi,
i need some help with deadening the outer door skins on my 300ZXTT.
i have mounted an 8" midbass driver on a solid door pod and attached it to the skin. now the skin shakes a bit too much for my liking... i need something to strengthen it and dampen it so less soud comes through from the outstide. the inner skin already has 1 layer of brown bread and will soon receiving another for good measure. i can't just apply brown bread because it won't stick well to the surfaced (whatever it is called, it looks like particleboard). Has anyone done this with good results before? i was thinking of fiberglassing the inside of the skin (for strength and creating a nice sticky surface) to then apply some brown bread or some spray deadner...

any sugestions on my ideas??.. any sugested materials?

thanks,
Marco

 

geez, no ideas?

 

Try fiberglassing the panels. You could even make a custom fiberglass enclosure for the speakers behind the panels ...it might take some time but it will be worth it

I've somewhat been through this with my car. I applied 2 full cans of Cascade VB1S to each door skin. Looking back, I don't think it made that much of a difference. Yes the skin is more dead, but the energy you are talking about is probably coming from the door frame, and then being transmited through the skin mounts. I've tried putting weather stripping on all the door skin/door frame contact points, but that doesn't dissapate energy. The weather stripping prevents rattles, that's it. My door skin still vibrates to the touch. While re-enforcing the door skin is a good idea, I think that going to the source, you vibrating door frame, is the best route. After all, if you control most of the energy in the frame, the skin won't vibrate.

I've got 2 layers of Cascade VB2 HD on the outer door frame, and 2 layers on the inner door frame. The door is pretty dead, but I'd at some point like to make it better.

Got any pics of the back of the door skin?
