I'm thinking about fitting Second Skin Damplifier or Damplifier Pro in the car (once i get one) was thinking of doing the lot the roof, floor, doors ect not too bothered about cost as i know it will be alot but my questions is. Is it worth the money to fit it in the all of the car mainly is the effect of the mats worth the money and effort to fit hope that makes sence and someone can help.
Cheers Tri

dynamat always helps door spks sound much better as do the door linings but you can get the same stuff as dynamat for much cheaper but without the name, google will help you with that! if you are going to have subs the boot is always worth doing to stop the noise being lost as you move forward ( or at least try too! ). sound deadening can add quiet a bit of weight too and i have never really heared of doing the whole car, give it a go by all means, i wouldnt like to do it though!

It won't be fun but you'll have a nice quiet car roadnoise wise and some nice deep bass as well, most demo cars for Rockford Fosgate, Infinity, Pioneer etc are sound deadened throughout and it does make a big difference.

was worrying about the wieght addition but then i thought i gonna make this a nice car not a speed car too young to die :P and i know i'd die with too much power/wieght so thought i'd make it nice but still keep the speed if i can if that makes sence and is posible

On all our demo cars we use Dynamat we have used other brands in the past and have always gone back to Dynamat it really good its not the cheapest but its worth every penny forum sponsor Rtuk can provide this for you. :)

ear plugs would do the same thing?
I've used flashing tape on my car, added about 4-5kg in weight I figure eat a few less McD/BKs/KFCs.
Done 2 layers in boot floor, doors, rear bench, rear 3/4 panel, and 3 layers behind speakers. Total cost of £30 for 6 sqr metres (64 sqr feet), in 10m rolls 20cm wide.
Overall effect is reduced volume from road/exhaust noise but still present. Might consider adding a layer of real sound deadening.

is that how u get rid of road noise den? :embarassed: because i might have 2 get some proper stuff lol
-
the basic principal of sound deadening is mass loading....the more weight you add to a body panel, the less its going to resonate....so you can keep as much volume in the car, without it being wasted making every loose part vibrate.
look here from the 2nd post onwards, http://www.golfgtiforum.co.uk/index.php?topic=49436.10
i layered the entire chassis of the car in bodyline, to replace the oem stuff that got waterlogged. i didnt really notice a massive difference to be honest, i suppose you have to do about 2/3 layers with the good stuff to actually reach any noticeable effect.
if it came to me doing it again, i wouldnt bother. it wasnt expensive, it wasnt time consuming, but i just didnt see any gain in anything. im not faulting doing it (because it obviously works), the only thing to bear in mind is that if your going to do it, do it properly and spend the money on good stuff, otherwise you're just wasting time and effort.

use loft insulation!!!! my mate has got it in his camper and it works a treat! it used to rattle like f**K with the 4 12" subs going off. but since it was striped out loft insulated and rebuilt the rattleing has gone!
cheap as chips to! :grin:
-
The best points to hit are the lighter panels that resonate. These are usually the doors as they have no stiffening ribs. Even the roof, but only if you dont have a sunroof.
-
I can see that loft insulation stuffed into voids and gaps might help to prevent rattles, but to stop resonance (which is the main aim as far as audio is concerned) you have to add mass to the most flexible panels - especially directly behind the speakers. This lowers the resonant frequency of the panels, which in turn prevents them from colouring the sound from the speakers.
Deadening the rest of the car will also reduce general road noise, which will also improve sound quality from the stereo. I once worked on a 3 series BMW which had had it's entire roof replaced (it also had no sunroof), but had not had the stock deadening replaced, and believe me, when you shut the door, it was like being inside a steel drum!!
The cheap deadening often works just as well as the more expensive stuff, but you'll end up using twice the amount, as it's invariably thinner.
