<{POST_SNAPBACK}>ya i had the same toughts at one stage but the whole weight factor mightn't be sufficent!?!?!
There's mixed reviews about dynamat, some say its great and then others say your just paying for the name and that there are other similar products on the market for better value. I havent seen or heard of anywhere in ireland (yet) that supply this type off matt so the price in posting from england usually is mental. My main problem is I'm a student with no money so I tend not to look at the stuff on the market. Had tought about using 'cow mats', that's not the name for them i know, we had them on the floor at work in the shop behind the counter, their like an inch thick rubber mat. The weight of them might cause the car to loose some power.
I'll be sourcing a cheap version of dynamat and applying it to the inside of the doors and quatar panels and then in the back (mines 3dr) i'll be filling behind the door cards with high density insulation. Then i'm boxing the arches in the boot and filling the area behind with insulation too. I'll be putting the insulation into sealed plastic bags as the condensation off the metal would ruin the insulation in time. Sounds a bit mad I know but it'll be cheap and should work as its the same idea as sound proofing a studded wall in a house.
The lads on here probally know more about it than I do, there's loads off info on google too if you type in variations on sound proofing. Try sound proofing caravan or something like that and more info will come up. If you have money it's easily done I suppose ha...
The stuff they use in office ceiling tiles does the trick. I have my Mazda RX7 boot done with it and it's fine. I can probably get some of it through work very cheap. That Dynamat stuff is v good although not cheap at all.... I'm sure it's fire resistant also.... You could use floor tile adhesive spray glue to keep it down, along with that tinfoil sticky tape (sorry don't know name of it).
