Not very. It's a hatch so you really need to do the whole interior to have a meaningful impact on sound.

I want to know is Dynamat or Q-Quiet what once is better????

Its hard to say which product is better since we only use what we use and not the other options. I used an insulator for ductwork bought at Lowes called Frost King. Looks just like Dynamat and a bit thicker. Hard to say since i never used Dynamat.

Only way to really tell would be hard. Since there are several ways to do this (lets just say 5 for this discussion, but there are many more), you would need 5 of the same car, all installed by the same guy using the same amounts of material, then driven and tested over the same roads under like conditions, and probably using a sound level meter to be scientific about it. Otherwise it's all just opinions and hear say. Installers might be able to give the best options, but their experiences can be flawed. Using Dynamat in a big custom van may make a huge difference, but using Q-Quiet in a Camaro might not make as much difference. And even if the installer did do 2 Z's, it would probably be weeks or months apart, and memories aren't always clear with this.

My recommendation after going through all the pain to do it would be not to skimp if you can afford it. Do some research on your own, pick a brand that seems to have a good product, and if they have different options, like thick = $, thicker = $$ & thickest = $$$. Go with the $$$ thickest of that brand and be done with it.

Dynamat has the name, but there are others that are the very similar if not exactly the same, and possibly even better. I chose FatMat because it offered the same sort of product at a cheaper price. If I had to do over I would have bought the better level material though. I just got the regular FatMat, but they make 2 other better ones. My mistake. But if you are considering FatMat, don't use Amazon or the like, because it will cost more. Go direct to FatMat and shipping is free. Also, do NOT buy the trunk kit. #1 it won't be enough, and #2, it's priced higher. If you want to do the entire trunk area, buy the 50 sq ft Bulk package, it's the best deal.

Yeah $50 and one hour of time to cancel out tire and road noise (and making the exhaust and engine sound better) is just INSANITY! Who has that kind of time or money?!

Sorry, but there is no way, no way you got it all done in 1 hour. Either you only did a very small portion of the back, or you didn't do a very good job doing it. Heck, unless you've done it all before and are experienced doing it, it takes 10-15 minutes alone to take out all the panels, foam, and spare tire, and another 10-15 minutes to put it all back in. So according to you it only takes 1/2 hour to put in the sound deadening material? You need to buy yourself a watch that works my friend.

I may have taken a lot of time to do it properly and nicely, but even scottIN took 4 hours and he self proclaimed that he did a sloppy job. This is at least a 4 - 10 hour job depending on how picky you are and how many patience you have.

I don't think he meant an hour literally. Obviously it takes more than an hour but the point is it's not a large investment for what can be (depending on your opinion) a large improvement.

It is def more than an hour if you do it right (thats what she said).

I had fun though, had a couple Terrapin Hopsecutioner beers on hand, my handy work gloves, some jams on the garage radio. Good times

Ever since I got a house, I fell back in love with getting to know my car's guts and privates. She so fine!
