Cylld - what brand/model tyres did you get?
I got a rough quote from Gold Coast Car Sound ~$700 for just 1 bulk pack installed. Due to the design of the Golf MKVI doors, they mentioned something about how the electrics/mechanics are designed, it is difficult to do the doors and can only place it as far as their hands can get in from the speaker holes. If I recall correctly, it was boot something and doors and thats it.
Pl don't bother commenting with a reply like that. If I wanted total silence and have the $$$, I'd be in a Rolls/Bentley
You spoke to me at GCCS yesterday, so I thought I would clarify for the benefit of everyone here.
Firstly, when people say 'dynamat' they are usually refering to the dynamat extreme which is used extensively in the car audio industry for minimizing resonance in doors, boots, roof etc. Dynamat make a variety of products that will aid in the reduction of road noise when used correctly. The dynamat extreme product is not ideal for sound isolation or road noise reduction, it is not designed for this purpose.
To reduce road noise using dynamat products you would need four different products for the entire vehicle. Dynamat extreme, dynaliner, dynapad and hoodliner. First you would treat the doors, floor and boot with the extreme product to reduce any vibrations coming through the chasis. As I mentioned to Gonsped, mk6 doors are relatively sealed, in that the electronics are in their own section of the door which prevents you applying dynamat extreme extensively through the door as we normally would. The only way around this is to remove the speaker and apply your sound deadening from the inside (very annoying). I'll dig up some pictures of my doors if people want to see the inside of a golf door. Next stage would be to use the dynapad on the floor, unlike the extreme product the dynapad is not adhesive, it is designed to sit in between the extreme and factory sound deadening. The objective of the dynapad is to absorb as much sound an possible before it hits the factory sound deadening.
Next I would apply dynaliner, which is an adhesive sound absorber, on top of the extreme in the doors and boot. This is what actually blocks a lot of noise from intruding into the cabin. Finally the hoodliner is a sound absorber used for engine bays, I would apply some directly to the underside of the hood right above the engine. The hoodliner is specifically designed for high heat and is oil/water resistant. Do not use any other dynamat product near your engine.
So that's the process using dynamat products, we have done this to a few cars in the past and results have been quite good. As you can imagine it is a huge undertaking and usually will take a shop at least a day to complete.
In all honesty for a brand new car I would investigate other means of sound isolation before you go to this extent. I completely agree with the tyre suggestion put forward by other members here. I had the standard Bridgestone RE055's on my GTI which I quickly changed to Continental DW series sports tyres for better performance, comfort and road noise.

To clarify, RRP on the dynamat bulk pack is $349 and I estimated $350 in labour which I think you'll agree for the size of the job is justified. To strip are vehicle interior to bare metal, clean it and apply the sound deadening is a very long process. The quote was a over phone estimate which I specified would most likely changed once we decided which product was going to be used.
