Help me get rid of the annoying vibration

I have aftermarket speakers and hu in my car, and last night I also installed a 75x4 amp. Well, I'm in love with my system now (after I added the amp), but at high volumes and loud bass, my door panels and the rear deck vibrate and rattle, which produce an ugly distortion. My speakers are doing fine though. Is there some way I could get rid of this vibration?? The rattling kind of messes everything up :(

Take the door panels off and apply some sound dampening on the inside off the doors. Heres some brands of sound dampening you can buy.........dynamat, fatmat, raam mat......etc.etc. I dont know what to tell you about the rear deck vibrating.

Install some sort of sound dampening like fatmat, dynamat, brown bread, ext. I personally like fatmat.Fortune: You will continue to take chances, and be glad you did.

How well does it work? Would it help remove all of vibration or just some? How hard is it to install?

How hard it is to install depends on how hard it is to remove the panels in ur car, usually easy but tricky. It is a foil and rubber combo that absorbs vibrations and sounds. Each brand has different versions of it, some versions are made to specifically reduce or stop vibrations and some are mainly to keep the sound in your car and reduce minor vibrations.Fortune: You will continue to take chances, and be glad you did.

Oh, removing the panels for me is not a problem, I was more concerned about how and where to place it in the doors and how it should be mounted or what holds it in place anyway.

You place it newhere you can. It has a peel away backing that exposes the adhesive then you just press it on and use a roller to smooth it out.Fortune: You will continue to take chances, and be glad you did.

I have heard that brown bread is good. You can stop vibration from your rear deck by putting some sound dampening material on it.

Yeah you can prob access it from ur trunk and you can just put it underneath if you can get it from the top.Fortune: You will continue to take chances, and be glad you did.

I looked at Dynamat website and there they had a "speaker kit" which covers a 10x10 area where the door speaker is, and there is also a "door kit" which covers the whole door. Would I be ok with covering only the speaker or should I cover the whole door? All I want is to stop the vibration (as much as possible), don't really care much about road noise.
