Okay, in preperation of the interior, I'm figuring out which way, lining wise, would be for the best. After prepping up the interior *cleaning it up and then primering it up), should I go with Dynamax sound deadning material, or more along the lines of like Herculiner?

 

There is a two part mat with aluminum backing that has adhesive on it so you can stick it on the floorboards to bare metal. Most of the car audio companies offer such a product. Then you spray that with the flexible stuff found in a can...Acoustimass or something like that....now you can drop the factory jute, or what's left of it, anyway after you pulled it to prep the interior, on top of that followed by the carpet.

You will notice a pronounced decrease in cabin temperatures and in the "rolling" noise of the car unless you have a gawdawful loud exhaust, which most of us do have...

 

The "two part mat with aluminum backing that has adhesive on it " you are talking about I mentioned above: Dynomat. I'm thinking that to be the way to go anyways. And I have no clue what a "factory jute" is.

 

He is talking about the factory sound deadening material that is most likely all cracked up and is 30 year old technology. Dynamat or anything else for that matter would almost have to be a better quality sound deadener.

 

Dynamat proper is an "asphalt" type material with adhesive and sometimes an aluminum front side. What I'm talking about has a dense fuzzy material bonded to the aluminum sheet. You could put down real Dynamat, then fuzzy, then factory jute, then carpet. Mercedes Benz tomb-like interior should be the result...

The factory jute looks to be some kind of woven or stranded material...normally, it's stuck to the back side of the factory carpet...

 

First question I have to ask is what are you goals? Are you wanting to cut down road/exhaust noise, keep the heat out or both?

For heat, find a lining that has the aluminum backing. Place that on the floor first, shiney side down, to reflect the heat. After that, it's noise suppression and increased insulation. Household carpet padding can be used in place of the factory padding, which is a wool/fiber mix.

If the padding is for stereo applications, Brown Bread is cheaper than Dynamat.

 

I'm looking for more what Mar3 said. M-B like interior. However, I don't want to be spending my entire time layering stuff down. I'd prefer just to lay down one type of material for sound deadning/insulation and then place new carpet over.

I'd like to keep as much road noise/vibration out, along with heat as well. And I'm sure that combination will of course help with hearing my stereo better.

Has anyone heard of any good reviews about HushMat? www.hushmat.com

 

I'm updating the speakers in my 80 RX and researched some sites about acoustic mats. Seems the DynoMat is a lot of hype: heavy, asphalt based (which I guess the cheaper quality stuff all is made from instead of butyl), pricey. The site recommended

sorry, don't have the site link of the tests...
Maybe worth looking at? I'm buying it...

It's a little bit of effort, but you're only doing it ONCE, for Pete's sake! Surely that is worth it...lol

 

I don't care about noise, but I do want to keep the head out. I tore out all of the factory crap down to the sheet metal, does anyone have a recommendation for heat insulation?

 

Same thing, just don't re-install the factory insulation...BUT, now you must go under the car and run a better heat shield to create as many air layers you can between sheetmetal constructions of your own devising to keep the bottom side of the floorpan cool...oh, yeppers...
