Sound Damping for the VX

[kpaske]

I'm interested in sound damping my VX. I'm in the process of installing a pretty heavy audio system and need to quiet down the interior a bit (especially after installing the PV Muffler!). I know a few people here have done this, so any advice would be appreciated.

I'm considering using a B-Quiet product, either Extreme or Brown Bread, but it's quite expensive and I don't know if there is a cheaper product out there that will do as good of a job. Also, I'm planning to do the doors, floor, rear door, and possibly the interior walls. I don't know how much I will need, and if I should do the head liner or hood.

Some specific questions: if you have already done this, what product did you use and how much did you need? To what parts did you apply the damping material? Are there any spots that would benefit from extra layers?

I believe it takes 3 of the biggest boxes of Dynomat Xtreme, to do the whole thing

So that's about 100 sq.ft. or so. Does this include doing literally everything, i.e. under the hood, under the dash, A pillars, etc. or just hitting the big parts of the interior (i.e. floor, doors & headliner)?

Also, is it difficult to remove the headliner and interior side panels?

I used about 36 sq. ft. of Dynamat and she is quite sound. I didnt do anything forward of the front seats except the doors and I am pleased. Too much Dynamat holds in heat (good for winter, bad for summer) and adds a HECK OF A LOT of weight (ya ya ya, slightly exxaggerated ).

All the aches and pains of installing it are worth it though.

I think 3 boxes covered the roof sides and floor of the VX. Not behind the dash or hood. I wish I could get a hold of Boarzhead since his install is the one I'm talking about.

So it sounds like a 70 foot roll of Brown Bread should cover the floor, 3 doors and interior walls, right? I'm thinking I might skip the headliner, as not much noise is introduced from above and that might let some excess heat escape. If I have some left over I'll work my way up the firewall, and if I decide to door the hood I'll probably buy one of the thicker materials that was designed for under hood applications.

So is anyone familiar with the B-Quiet products? I've heard nothing but good things about them, reviews have given them better scores than competing products, and it's a lot cheaper than Dynamat. Maybe it's just not used as much in the 'States because I think the nearest supplier is in Canada.

Ya, that sounds right to me, but if you ever plan on putting a system with a powerful sub in there then you should definately do the roof. I have 2 Sony Xplod 12"s and it shakes the hell out of my roof, I have to open the back door at party's or it sounds like crap.

F-Dynamat...... go with Cascade! It's a much cleaner install. It doesnt have the sharp edges that the dynamat foil has, and its cheaper!!

[kpaske]

Yikes! I am working on a high end car audio install as we speak- one of my main reasons for the sound damping. I suppose I need to include the roof in my install plans also then. It would be much easier to do it when I do the rest of the VX, and it sounds like I'm going to want to do it.

As far as holding in heat, does it generally work as an insulator? In other words, will it also hold in the cold if I'm using the AC?

I'm thinking about installing some kind of sound dampening material in my VX (floor, doors, etc.). Wondering how much dampening material I can fit under the carpets without too much trouble... half an inch maybe? or more?

Take a look at Cascades products, they have a liquid sound deadner that can be sprayed on, and it doesn't reek of MEK fumes either, its water based. They also have a thermal ceramic barrier compound that has impressive R qualities even in thin layers.

Hotsauce - How well do the cascade products compare to Dynamat and B-Quiet products?

SPAZZ - You can get 100 feet of B-Quiet Extreme for about that same price off E-Bay (plus shipping). And a 70 foot roll of Brown Bread is about $125. Everything I hear indicates that BB is a lot better than Dynamat. I just wish someone could tell me something about BQ Extreme, but I can't seem to find anyone who knows anything about it!

[kpaske]

Yeah, eBay has Dynamat for just under $100 for the 36 ft. roll - usually around $97-98 plus shipping.

What is a side window wind guard?

Hey kpaske, I would install the system while you still have the headliner off. I say that since the roof has sooo much flex to it and you might even need to double up on it. But, I would wait and try it with one application and if it still moves with that horrible vibration throw another on.
