im thinking about dynamatting my car, but what exactly does it do? do i just need to do the floor and the trunk or every metal piece? dynamat is expensive and i would like a much better alternative... any ideas?

is it needed? if not then i don't wanna do it, please let me know

 

Dynamat helps seal out all outside noises. Helps with interior comfort such as great quality sound out of your speakers. Less resonance/vibrations.

 

Doing the doors and the wheel wells will also cut out alot of road noise.

 

If costs is a factor use only dynamat for behind/around speakers. Then do your entire car.

 

idealy you want to do as much as you can, i wouldnt use dynamat now a days, ther are better products.

one advantage among many is the luxury car feel it can give, you close the door and are in a nice sound cacooon lol.

 

what other materials are there... please let me know... how is peal and seal i want something that is durable

so trunk and doors first? all around under the door panel? i take off all the plastic water protecting it right then do it under it

 

There are.... DynaMat, HushMat, Stinger Road Kill (What I use), second skin, bull ****, there are endless companies that make it but its pretty much the same, I use the stinger stuff because its very easy to use and it doesnt squessh out all the sticky stuff and keeps it on the backer

 

interested as well

 

my research showed up

http://www.sounddeadenershowdown.com/

so from what i see damplifier is where what its gonna be, about how many sq. feet did you guys use and where did you apply it?

 

peel and seel is crap.. What you want to look for are butyl products. Second skin is my sound dampener of choice but like a few peeps have said there's several different brands out there.

Mind you any vibration dampener doesnt need full coverage to work. Assuming you only have 10sq ft... you will get alot better results use just lil patches throughout the car then using all of it in the doors, or trunk or whatever

80sq ft shoudl be plenty for the whole car... Personally ive used ~170sqft

 

is that with the two doors done (inside and under the door panel) trunk and floor?

 

yes 80sq ft will be enough for the two doors trunk and floor. BUT you have to make sure to evenly distribute the product.

 

okay... other wise ill hear minimal vibrations more?

 

in all actuality the whole car is rattling so applying a million sq ft on the doors isnt going to help your trunk

 

^^^ lol

 

i never said that

 

I suggest checking this stuff out, you can get it in liquid sound deadening and peel and stick, they both work great! but you really dont want to get the v1, if you want something good get the v1SE. Also if you want it really thick in some areas I would suggest the v3. I have used all of their edead products and loved them!

ehh **** edead. I got some for free and detemined i would be better off not using it then putting it in my car. Spent months figuring out where i could put it (moms car, computer, ect) and not waste it yet not use it in my car... Ended up wasting it anyway since i gave it to a douche bag that put it on a cinder block wall for fun

i know i was just trying to make a clear cut example of what i ment. even the littlest amount will help but its all about placement.

i in no way ment to offend you but im a little blunt

 

yea i figured i just wanted to point out that i was somewhat confused... and no i understand now

 

Yeah you have to take him with a grain of salt.

It used to take me about a week to feel good about myself again after he would comment on my posts

 

lol hope not because id always comment on your posts spun. I seriously think you know quite a bit about what ur doin

 

i used fat mat, it works great for me. no rattles and the road noise is much less. i got 100 sq ft for like 120 shipped and i have almost 40sq ft left over after doing the entire trunk, wheel well, rear deck top and bottom, rear seat and the rear sides. when my back stops hurting from five days of doing it, ill do the front doors and stuff haha

 

Read my thread:

I did a nice little write up on exactly what you are asking about.

is there a how-to on how and what pieces are best sound deadened. That would be useful

Ok forget it. Just looked up a few posts lol
