prob works to cut down noise but prob not so good for audio. weight stops the metal from vibrating and making the speaker loose energy ( notgood ) sooo no weight = almost the same as stock doors

I think he wants to make the car more quiet inside. Foam/insulation is the way to do this. For sound vibration you'd need something like a dynamate material.

correct this is what im looking for

but that would also help disortion in the car!

I'm not worried about energy loss, I will be feeding my subs over 2400wrms from my back seat and my front componets are getting around 600wrms each. (that's if I will be able to supply the amps with enough current!)

do you recall if it was a closed cell foam?

I have used 1/2" closed cell foam insulation to line the interior of my work van. It does a good job keeping the body from ringing like a bell when the tunes get loud and it acts as a pretty good thermal insulation as well.....

A layer of it glued to the inside of a buddy's van door panels did a decent job stopping his doors from vibrating....not the exact same effect as Dynamat or similar products but much better than nothing....

The weight of those types of products cuts vibration by raising the resonant frequency of the panel.....foam works by absorbing them and keeping the door panel and the inner door skin from bouncing off each other......

where did u get the 1/2" closed cell foam? This is exactly what I am looking for.

I have a buddy that works at a place that imports very large rolls of conveyor belting from Italy......they wrap it in the foam to protect it and when they unwrap it I get a piece about 12' X 15'.....

Pain in the butt to wrestle with but a little spray glue and that piece covers the sides and the roof in an E150 in no time flat......
