Hey Guys!

Just curious if anyone has tried installing dynomat or a similar product under the trunk of their Z to reduce some of the road noise? Thanks for the input guys!

I did a single layer on everything behind the seats and double and triple layers over all four of the wheel wells. The noise from pebbles and stones is greatly reduced.

 

how about exhaust?

 

It should help but you should consider other materials to use with it to make the biggest difference (jute and neoprene layers). Once you get the trunk area quieter you will notice how noisy the front of the car is however. Trunk is an excellent place to start, don't forget the empty area behind the seats under the glove box and behind where the Bose sub goes. We all call that the cubby area. Do some searching in the audio forum and let me know if you need us to point you to some helpful threads. I've got to go for now ...

 

Go with FatMat to save some $$$. Works just as well as Dynamat.

I have a ton left over from my door speaker install, so I want to start layering up my hatch area. Pebbles are damn loud!

 

I have Dynamat on entire rear area as well as doors. I have a sub integrated into the spare-well so I need it.

 

i use stinger expert road kill

ALOT OF IT

 

That brings up another question....

Is it difficult to wire up an amp and sub to the stock (non-bose) headunit?

 

How does all this matting affect the weight and performance of the car. I know that fat mat for example is pretty heavy stuff.

 

I painted 2 layers of E-Dead then one layer of dynamat on top of that....

 

if you're gonna buy dynamat buy it from here its a lot cheaper than stores or other sites:

Not anymore than a sub+enclosure. My 50ft. roll only weighs 10-15lbs, and I didn't even use half of it for my front doors. I don't think you need to worry about the weight.

 

I understand that installing Dynomat or any other similar product is done to quiet down road noise, but does it also work well to quiet down the rattles in the interior???

 

I bought the generic version from PartsExpress.com . I used it in tandem with spray in bed liner. It was only a fraction of the cost of Dynomatt and has been working really well for a few years now....

 

it effects it a lot. 100ft of the thicker stuff weighs at a hefty 100 lbs.

like another person said above, juse some jute. Expensive but lighter. I don't want to use any type of asphalt based ones like most because i intend to keep the car for the rset of my life. I dont' want that crap on my car.

 

No, but you probably won't like it without a lot of EQ. The factory non-bose headunit has a low pass filter below 100Hz. At first it is an improvement but within a couple of days you will notice the deep bass is missing. You won't get the bass you want without a lot of hassle. It is there and has to be boosted back up and is pretty much impossible to get real smooth but can be brought back to a decent sound. I did it not knowing and ended up with something decent after a lot of trouble. I think if I knew it up front I'd hide a second HU somewhere and ditch the factory one but I wanted the factory HU in place for secutiry reasons. It's worth a shot using it though. The worst thing that can happen is that you don't like it and then have to buy a HU. How far along are you in the planning and what is your goal, etc.? There are a few directions you can take on a simple system. Have you checked out the audio and visiual section??

 

I had a truck a while back that I had an MTX amp and sub in. I have them lying around and I was just wanting to do a simple install with the stock head unit. I'm saving up for wheels right now...so I cant really do a new head unit...lol.

 

If that is all you are after right now it would be an improvement to have a bigger speaker in there for SOME bass. Just get a line level converter and tie it into the speaker wires to feed your amp and sub. An improvement on that is if you have an EQ laying around put it in between the line level converter and the amp input and take the lowest eq slider (the lower frequency the better) that is probably at 60Hz or hopefully 40Hz and boost it all the way up. It shouldn't end up overboosted because 20Hz to 60Hz or so is almost non-existent out of the HU becuase of that filter. That way you can gain back some of the low end. It won't be what you want in the long run but you will have some bass.

 

Last week I started installing a liquid sound dampener called QuietCar. It made a huge difference on the areas I got to install it on. I was planning on completing the install in the trunk tonight....however on the way home today, my car was totalled. So I do not have a final conclusion on how the product is, but based on the limited install I had completed, I give it two thumbs up. I bought the 5 gal. liquid version of it. It seems like it has a much, much better potential than the traditional asphalt based mats. I'd suggest reading up on it before you buy anything.

 

Any thoughts on the above?
