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 have used X-mat (about identical to dyna-mat) on all my vehicles that are running. 914 isn't one of them yet. On the doors, remove the door panels, cover all the area behind them on the doors, put em back on. You should make sure that your back glass and door/window seals are all tight before doing the inside firewall or floor. you dont want water to find a place to sit. The more you use, the better, don't be stingy with it. I saw a product called "lizard skin" used on horsepower tv a couple of weeks back on their 55' fiberglass body. If'n i remember right, they said that tiny air bubbles are trapped throughout it when it is sprayed on to absorb sound and heat. might be something worth trying.
