Dynamat Sound Proofing, Anyone Used Dynamat on firewall/floors Options

[yellowFV]

Anyone have any experiences in improving the sound proofing in the 914 ?... I have a 74 1.8 liter that is my semi daily driver and the Engine Bay Insulation peice as well as the insulation panel behind the backpanel is missing.

I am looking at replacing the engine insulation panel with one of those foil types that is avail on ebay !

George at AA recomended the stock stuff.... I saw in the October VW Trends mag they are "soundproofing" a bug using a multi-layer foil product called Dyanamat. www.dynamat.com.

The stuff has a neoprene rubber base layer a 8 mil lead sound deadening layer and a foil outer layer..

My plan was to use this stuff on the backpanel/firewall as well as the floor and on the inside of the doors glued to the inside of the steel door panels. I was hoping to get the car quiet enough to be able to install a CD Player/satellite radio with Amp and Speakers in door panels.

The car handles like all get out... just trying to make it more comfortable to drive and be able to enjoy a modern sound system.

any thoughts or ideas on the soundproofing or the sound sytem / speakers ?

I've installed the shiney stuff. Put a piece on the back side of the engine lid as well. I'm not sure I agree with Headrage, I think you need absortive material in there. I'm not sure on the durability of it yet though.
But what worked more than anything else was going over the engine tin and heat exchangers tightening all the loose stuff. Also getting the window lined up well and replacing that inner fuzzy strip stopped my windows from rattling. All these things were a lot looser than I thought would be the case until I started checking especially the cooling tin under the cylinders and up to the h/e.
