take out the dashboard, u can stick at the inner side of ur firewall

I think the most effective you can do it is do it from the Engine side... because I have done it to my friends car... but is really limited place for you to stick on the Sound proof material... especially the cooling coil side... and... the effect is not that much.... to dismental the dashboard take alot of work.... think twice..!! if you want to go quite.... spray some foam in the windscreen pillar...

bitumen pad won't help much in supressing noise. They are not invented as sound deadening material in the first place. however, its kinda popular as its easily available and cheap.

Here you goes... some idea for you .... we took 2 days to settle it...

wow.... nice work.... but kinda messy.... hahaha... hows the improvement??..

 

[zane222]

we used the RTA to test it... about 10 - 15 db reduced...

wow. that's quite a lot of noise reduced.... but have to DIY ler... if pay someone to do, RM400 for workmanship also not enough.

4 pcs of dynamat already cost you 300 already....

[zane222]
