Dont flame me .. I just asked a audio expert .. An installer not a seller

Dynamatt doesnt do much .. It reduces slight vibration but cheaper options also work well .. In his opinion he said its not worth it .. Oh this was in the boot .. in the doors hes all for it .. but still says its better just to do the surrounds to reduce weight ..

Out of interest, what were the cheaper options he mentioned?

well one was expanding foam (rookie told me that one and no way I would do it ..)

He explained padding foam would work if its hard packed and making sure everything is tight... He told me cheaper version will do just as good but we had the system running (boot closed) I grabbed the spoiler to shut the thing up and he said thats what dynamat will do.. It was a noticable difference but not $100-200 worth of it .. even tho the system it worth 50 times that much he still didnt feel you would hear the effects in the cabin ..

Dynamat is not made to reduce rattles, unless you use the one thats specifically designed to reduce rattles.

I would tell your installer mate to go back to school and have a few more lessons in dynamat and reduction of road noise.

Also EXPANDER FOAM do you even begin to understand the catastrophis results EXPANDER FOAM will have on your panels when it starts expanding? Its been known to warp the cars panels.

Im just preachin his word... Obviously he'd know something.. hes been in the business for 10 yrs so I dont know..

Everyones got a opinion so i guess thats his .. not that I dont believe u either but id like to hear before I buy..

One more thing I doubt hes studied it hes just used it and felt it was worth less..

Well i use it and have demonstrated the differences time and time again. So i dont mean to sound arrogant but perhaps he was using it to STOP RATTLES not to REDUCE ROAD NOISE.

Dynamat is proven all over the world as being worth its weight in gold, and is being used by every single high end installation expert and SQ nut.

Lets agree to disagree, but when applied correctly and utilised properly Dynamat does a LOT.

How much would it cost to do a DECENT sound deadening job (diy of course)?

I knwo that everyone's decent has a different meaning, but lets just say such that the car becomes significantly quieter so that you can actually hear it. Not like a 1db drop that can only be detected using a db metre.

Would that just be doing both doors?

possibly parts of the boot/rear quarters?

underneath the rear seat?

rear seat sides?

floor?

roof?

behind dash?

$300ish for dynamat bulk pack, dynaxorb and a bottle of prepsol.

the rest is elbow grease.

a bulk pack should do both doors and leave you enough to get stuck into the boot and some under the rear seats if you haven't had enough fun yet.

alternatively, phone a friend and you could probably do the doors on two cars (with more dynaxorb for the other car) and see how it sounds.

if you want to go further at a later date then save up and buy another pack of dynamat and a few beers.

best way :laugh:

or work it on this: 88/hr average 3-4 hours to do a car and a box of dmat.

Just to respond I dont disagree with u .. from the info i got it was exactly as you say worth its weight in gold. But hey I might give that gear a go neways with a 40kg enclosure in the boot aint like 10kg is gonna hurt my ride any more ..

      Use text replace function to auto-link to referred threads?

      Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...

      Yes, a plan for non-action is always my first sort of plan! I'm happy to see what falls out of invision's update. I had been having some thoughts on what to do with this the other day and they all seem to have fled my memory, after various solar panel induced traumas, squeaking suspension sphericals, etc etc, over the last little bit. I'll try and recall what I had in mind and make sure that I put it into print in some form before the Alzheimer's strikes again.

      The ability to have both a 5500 stall for launching, and a regular lockup for every other scenario is pretty sweet. Does it actually work well like that though in the real world? Would it hold up to track use and otherwise you'd never know you had a stall converter in it? If so, that's awesome

      The thing is, once the content has been tagged we can chop and change the end result as much as we want. Its identifying the content in the first place that needs to be done regardless of the final outcome.

      Sorry @GTSBoy I thought I'd replied here. There's a new BIG version of invision coming out soon, it might be worth waiting until that happens as it contains a lot of improved functionality for tags. My suggestion would be to add a top level page (not thread) with some info on it and then link to sub pages for various topics. We could even just start really simple with 2 or 3 pages underneath it. Those pages could just have a view (like a pre configured search result) of the tags we choose to put on it. We could have some background or an intro on each of these pages. My only issue is that while admins and mods can update the existing content to contain the tags we want, new posts can have whatever tags the author wants. That said, the reason our tags are so messy is because of that, so maybe we restrict tagging to admins/mods in edits.
