One way to get around this is to try and source a good looking speaker grill and get rid of the so called speaker pad. I am assuming you are talking of the plastic grill that sits on the door pad covering the speaker.

Try and get a thin sheet of rubber along the circumference of the speaker pad. Try and post some pics, lets see if we can come up with better ideas.

Are you still using the OE speakers and grills? If so, take out the grills, take 2 pieces of 1"x2"x1" open cell foam blocks and stick them to the door pad with rubber solution to the left and right of the speaker, and push the grills back in (the foam should compress). This should reduce the vibrations.

The vibrations coming to the grill shouldn't affect the music, unless it is making the grill rattle.

Well, test drive cars are most definitely in worse condition than your new car being delivered. Another thing is that in general driving in the city, you will hardly rev over 2500-3000rpm anyways.

As for where to get your damping done if you decide on doing it, i cannot help you there as i dont know about damping places in Delhi. But yes, do drive your car a bit to see if you really require it.

The wind noise at 100+ speed on highway was always a bother for me in my Octavia. I was not very convinced that dampening would NOT be of any real help for wind noise.

After a search in SP road area, I managed to find a "D" profile rubber strip, which I have gluded to the edges of the all doors including the large rear door. I have not tried the car at high speed yet, but the reduction in outside noise is very significant. All this for Rs.680/-. Really worth it.

Encouraged by the result, I dampend both the front doors with a acoustic material called "Aura<something>>". The installer was not at comfortable pasting the whole sheet...but regardless i insisted. There was quite a significant amount of reduction, in what i originally thought was part of the engine noise. A very low level humble that used to bother me, has reduced significantly. Guess the proximity of the front door to the engine related vibration was causing all that low level rumble!!

Next I indend to dampen the trunk...as most of it just plain metal sheet (with a little dampening already thrown in by Skoda). I guess dampening the area above the tyres would in particular be of great help. I'm planning to use ArmaSound...it kind of stinks at the momement. Any one had any "stinking" issues with ArmaCell/ArmaSound ?

^ Can you please post pics of the rubber strips installed ?

Sure. I'll drive a bit and then ascertain if it really needs damping. Thanks.

+1 to that. I would be interested as well.

Thanks DerAlte and rjstyles69 for the suggession. However, I guess it came a little late. I found a better and rather simple way of doing it. I used a little rubber based glue on the edge of the speaker cover (Yes, the plastic thing which comes as OE) and fitted it back. It has stuck to the door nicely and no more vibrations from it

How did u stick the "D" profile rubber strip (what glue) ? Why did you not try sticking the "D" rubber strip over the existing door seals?

I got dynamat extreme from US, Pls suggest any good installer in Faridabad or Delhi

Sorry was travelling and could not follow up. The stink from Armasound is gone. The overall noise reduction is very significant and makes u feel even more comfortable at higher speed...highly recommended. The low-freq rumble of the engine is greatly reducted after the damping.

For wind noise, I used a D-Profile rubber that i purchased locally. However, it deformed very quickly in the summer heat. I've ordered this...

In the meanwhile, I've sold my octavia - due to the Yeti temptation with the on going promotion.

How is the sound insulation seal strip doing? how does it fare against the d-profile purchased locally? If its good I am also planning to order this.

Has anyone tried Armacell for damping their cars ? Contacted their dealer in Bangalore for a demo on this product and never heard back from them.
