(http://www.dizzie.biz/golf/dynamatextreme.jpg)
just spotted this and have you done both doors and what kinda differnce has it made to outside sound and speakers sound curious to know if it kills off alot of road noise through the doors as im still not used to my mk2 i keep thinking a window or door is open :S
-
road noise is dramatically reduced! I was so surprised how much difference it actually made! stereo is better, but I'm not running a huge ammount of bass though my door speakers. but the road noise is seriously reduced!
and yeah, I did both doors. the other got done a couple of days later.
-
How much did it cost to dynamat both doors Dizzie??
-
I went OTT on them and used about 3 sheets a door I think.
From www.dynamat.uk.com you can get 9 sheets for £150 and have enough to do the rear quarters too. I didn't do my rear quarters as they're slightly rusty so when they're replaced I'll do them
-
Blimey 3 sheets! I've just done the boot with 3 sheets, and also came across some wool wadding we use to soundproof helicopter cockpits. It gives the door closure a merc style sound. I think I'll use a bit more dynamat on the doors, oh and by the way I paid £150 from www.caraudiodirect.com - just in case dynamat themselves haven't got any.
-
P&P is free from www.dynamat.uk.com though ;)
CAD is £10 aint' it?
-
I think it's only £6, but free is better!!
-
yup. all dynamat off the site is free P&P :D
-
Hey boys! I hate to tell you this but that is a total waste of time, effort and money!!
Now this is serious i aint joking and a little lesson in metal strength too!
The inside skin of a door is quite strong and does not resonate! Why because of the rolled edges to the holes!
They act as strengthening bars!
The stuff should be applied to the inside of the outer door skin!
Yes that will suppress road noise - but it wont help your sound system!
Seems to me that all people want to do around here is sell loads of Dynamat.
How much is the commission????
-
It's quite possible Len you've never had a loud enough system, because regardless of how many swage lines you have on the exterior of the door it will vibrate (resonate). Plus if you remove the door panel of a MK2 and close the door, it resonates like buggery, hence the reason for fitting sound deadoning to stop vibrations.
I work with helicopters and they have a sh1te load of sound deadoning to stop panel vibration and cut down on turbine noise, so I personally would say it does work, and is worth carrying out on cars whose owners are serious music listeners.
Dynamat isn't the only product out there, it's just been recomended to me by more people than I care to name, and if you can afford it 9 times out of 10 you buy 'the best'. IMO
By the way, just in case some commision is available my paypal address is.......................................

it does help reduce road noise and increase your stereo. I've just put 2 15" subs in my boot running off a 1500w RMS amp and the panels I haven't done you can see them moving! The roof, rear quarters and tailgate are actually bulging when it's cranked up to the full.
my bosses' A3's are both done with Dynamat extreme. the roof and whole back end are completely covered as well as both doors and the sound is awesome inside. they both said road noise was reduced and this is in a '54 plate car so imagen what it's like a in '87 mk2.
-
Well i aint really started on my Golf yet, but the system in my 405 is powerful enough to vibrate most of the car!
And yes i have used Dynamat in selected locations! Outer skins of doors etc and around the sub box. Its all due for a rebuild as some of the actual build and bolted connections can be improved.
In other less important areas i have used roofing felt!
I just dont see the point in spending loads of money where it aint needed!

Another thought - Lewy if you get the same kind of vibrations in a helicopter as you get in cars i would have thought that could cause serious damage to your health!! :evil:
Have seen a lot of stuff spouted around here lately and here is another little gem for y'all
Fine build up of door pods etc. and sure they will look great but at the end of the day most of these still rely on the door cards and their flimsy plastic clips! The odd screw here and there.
Now what i have done is to build in metal brackets to the door pods and fixed these to the inner door skin.
Does make the build a bit more difficult, in that you have to use a bit of inguenuity to hide these fixings. The way i did it was to mount the speakers (Infinity 6x9s) on the outside of the pods, so that to gain access or remove the door cards/pods, this gives access to the bolts holding the brackets to the door.
This gives a nice solid basis for the sound box/speakers and doesnt add to the vibrations!

Not far off, we fly the PUMA (Permanently Unserviceable Military Aircraft), and it's like sitting on a spin dryer on max chat!!
Gives you right semi I can tell you :shocked:. So in essence it's very like driving my MK2 :laugh: :laugh: :laugh: :laugh: :laugh: :laugh:
-
I'm going to cover the inside of my door card in fibreglass. that'll make it solid as. then add a few more places to attach it to the actual door.
-
Fibreglass still rattles!
The only way is to mould in the speaker surround and secure it the best you can to the inner door skin!

I came across this stuff.

It seems to be a real good price. Im planning on getting a 50sq ft roll. What areas should i do? Gonna do the doors 1st. Is it a good idea to do the inside of y sub box or will that kill the bass?
