Here is my original post:

You can click on the dropbox link to see the pics. In the last pic I used the last 2 full sheets under the back carpet. I used a radius cut where the battery and the storage is on the opposing side. This way, I can access that area easily. Simple and effective mod!!

Best

So, is everyone just covering behind the seats and the rear deck area, or is anyone pulling the seats and covering the whole floor?

Trying to figure out if it is worth pulling the seats and doing the whole thing.

How much do you like projects? the biggest problem is the majority of sound comes through the bulkhead. Obviously it comes through the whole car, too. But the bulkhead has virtually no insulation on it underneath the carpet except a little bit of foam and the huge rear wheels are 3 feet to 5 feet from your ears, so covering the bulkhead is where the majority difference is going to happen. Now if you like projects, up to you if you want to do more.

I didn't want to make this a huge production, when I first wrote it here. I was on a road trip I had 1200 miles to go and I noticed that my run flats were loud. So I did a peel and stick on the bulkhead, and just laid the rest of it underneath my cargo mat. Took 45 min with no tools, except sissors.To my surprise it solved the problem and I haven't done anything else. Nor do I plan to. Too many here are starting to overthink this.....its a great mod with NO downsides, and a great starter mod if youre new to doing projects on your car, right up there with splashguards, IMO

Yea, I am trying to not over think it. I had a recent road trip where the road noise from the tires was unbearable. So based on that the bulk head behind the seats is a must. I am not trying to make the car silent, I am just trying to get the most bang for the buck (buck equaling both time & money here ).

I am trying to decide if it is worth pulling up the seats, but I am not sure just how much noise is coming from there, versus the rear area. If doing the rear will eliminate 80% of the noise, then I would probably stop there. If the rear only eliminates 40-50% of the noise, then I might as well do it all at once.

Then obviously do the back, see how that works , and then the front if you need to. Impossible to tell because were all different . hearing is a little bit like the color , you choose as it's all personal as to the level of quiet we want. Based on the difference it made for me , I think you'll find the back coverage is good enough.

Driving my new Z06 I definitely feel the booming noise from the runflat tires is coming from BEHIND my head. Trunk and rear wheel wells IMHO...

And the bulkhead, which is BEHIND, your head.

Sorry that this is little off topic..and that this is possibly a stupid question. While I'm installing the Fatmat, I'm thinking about running a power wire (not connected) in case I add a radar detector or something later. I figure I might as well while I have everything taken apart for this and would just keep the extra looped up behind the seats. Can anyone suggest a generic power wire to run or are they usually very specific for each type of detector? I've read through many of the extensive radar detector install post but haven't seen anything on this in particular.

Much better off by posting new on this as it hijavks the thread and many wont see it. Power cord is generic with the right connector. Id use 14 ga wire or so. Shielded will be easier to run.

I hear you on that and I definitely don't want to hijack the thread. Thanks for the suggestion.

I noticed the same thing on some other products. Leaves a bit of a bad taste in my view. (Yeah yea, I know. "Just business" yada yada) It damages my view of Amazon as a "go to vender".

Hey gang, this "sounds" good but I'm a little concerned reading this old thread from the audio forum:

https://www.corvetteforum.com/forums...-products.html

I don't want my car to smell like asphalt--any of you installers have any issues with this?

Yeah I saw that and was wondering as well. I might buck up and get the more expensive stuff just in case. One guy claims it still smells months later.

I did the back a few days before I did behind the seats.....IMHO the back was an improvement, but behind the seats gave me the biggest benefit.

Actually, I wouldn't mind seeing that list. Might save me a lot of wasted time!

Still think the best idea is do the center of the panel only (which is where the vibration occurs) with fatmat or dyamat to minimize the amount used and do the rest of the panel or panels with Frost King which is a closed cell foam product designed to absorb sound. Much cheaper , has no smell , will not dry out like the ashphalt products and absorbs sound (just not as much vibration as the heavier mat products). You could get away with a very small amount of the butyl or asphalt product and do most of the back panel and/or trunk area for a very cheap price using Frost King which is much lighter. Don't be fooled by the name , Frost King is designed to reduce noise by absorbing sound in its foam and aluminum structure. Dynamat and FatMat are designed to absorb vibration which reduces sound as well. You need to do both in a car , absorb vibration which creates sound waves and absorb transient sound. These two products would work nicely together and you could save some money.

agreed....amazing that some will believe an old audio thread vs several people here that have done it on their car and report no smell.....
