Sound Deadener?

[xx24xx]

Did you prep the surface with Acetone first and apply with a heat gun and roller?

Hi guys,

I am upgrading the whole sound system and looking into sound deadening materials. Looking up I found two types,

1. Dynamat ($135 for 36 sq.ft)
2. Fat mat - ($130 for 100 sq.ft)

Any opinions and how well the fat mat works? or any other suggestions?

The dyanamat extreme bulk pack will be enough to lay down for the trunk alone, wont be enough for the doors and the insides, any other suggestions?

You can find Dynamat Extreme for cheaper than that. Ebay it...

Not that I'm using it for audio reasons since I have only the front door speakers. Mostly to keep road noise out and heat in. Since I removed all the stock tar and carpet from the floor boards and trunk. Not looking to spend a ton here.

Home Depot roofing stuff for us DIY'ers on the cheap? One of my friends used Dynamat (not sure what kind) on his miata and he said it really quieted things down. Found 50 sq. ft of the dynamat xtreme on ebay (with roller) for $90 shipped. Looks like enough to cover what I need. Good deal?

dont bother with the roofing stuff.

seems like an ok price on the xtreme...

one layer on the trunk floor is short of 40 sq ft of raw (uncut) deadener...so thats an idea of coverage, although you don't need a solid layer. do the "tap test" and see what panels make noise or vibrate.

i use the scosche accumat, works really good

The Dynamat xtreme pack is only 36 sq. ft.

So you will need more than one pack to cover the entire car....

As for the price on ebay that was the cheapest I could find, even if the pack is cheaper, shipping kills it.... $134.00 was the best.

The other site posted was 119.99 +24.99(shipping)

That is where i am stuck at. I have one extreme pack and I need more to cover the rest of the car and on the highway the noise is high even with the windows rolled up, sounds like wind blowing inside the car. , and looking at second skin with that butyl spray thingy I hope it may work out better.

Right now I am just trying to save up some money to finish this project up and then move onto the suspension and the wheels.

i think greg is looking to put some deadener (back) on the floor...

and it seems like both of you are trying to kill road noise. i believe the best product for that is SS's luxury liner since you need a barrier, not just a mass loader like dynamat. mass loaders prevent panel flex, reverberation, and vibration.

Yea road noise is all I care about. Floor and trunk.

Sorry...it was "B-quiet" sound deadener. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150380517160&viewitem=&sspagename=STRK:MEWAX:IT

never used that stuff...it should work ok for your purpose.

it comes down to thickness, stickyness, and materials. the cheaper it is (in general), the more it's lacking in at least 2 of those areas.
