Dashurik Posted August 4, 2013 Share Posted August 4, 2013 Hi,guys! As You all know 350z is not the quietest car,road noise is very present in the cabin.I also installed new aftermarket sound system,which I like ,but on the high volume Interiour panels rattle and its not a nice feeling. So,my plan is to soundproof the whole car. Does anybody here did it before? Which materials have you used? Which company and how much you paid?

spursmaddave Posted August 4, 2013 Share Posted August 4, 2013 Depends how much you want to spend, dynomat is pretty expensive, a Zed is never going to be a quiet place so I used brown bread soundproofing Quote Link to comment Share on other sites More sharing options...
Wasso Posted August 4, 2013 Share Posted August 4, 2013 There's also this stuff which I stumbled across today (whilst also investigating sound deadening) Quote Link to comment Share on other sites More sharing options...
Dashurik Posted August 4, 2013 Author Share Posted August 4, 2013 Depends how much you want to spend, dynomat is pretty expensive, a Zed is never going to be a quiet place so I used brown bread soundproofing I'm not too sure how much to spend yet.If its way too expensive than I may just leave it as its.Just wondering what experience installers will charge for the whole lot.

Dashurik Posted August 4, 2013 Author Share Posted August 4, 2013 (edited) There's also this stuff which I stumbled across today (whilst also investigating sound deadening) Very impressive results! Interesting how much weight it will add if to do the whole car(not too bothered about it as I'm not using my car for track)? I will check them out,hopefully they sell it in uk...

You will need to do doors, behind the seats , rear strut, boot floor at the very least. Its expensive as obviously all the interior needs to come out Quote Link to comment Share on other sites More sharing options...
Dashurik Posted August 4, 2013 Author Share Posted August 4, 2013 140$ for 40sqft Then we looking at postage and custom charges...all in all around £130 i think,which is slightly cheaper than buying dynamat from uk seller(£140 incl delivery) Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted August 4, 2013 Share Posted August 4, 2013 6ftx6ft wont be enough though I doubt..... Quote Link to comment Share on other sites More sharing options...
Dashurik Posted August 4, 2013 Author Share Posted August 4, 2013 6ftx6ft wont be enough though I doubt..... Agree...I think I need two or even 3 rolls of it.. Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted August 4, 2013 Share Posted August 4, 2013 6ftx6ft wont be enough though I doubt..... Agree...I think I need two or even 3 rolls of it.. I would say 1 roll for the boot alone then 2 for the cabin (doors/area around rear speakers/ floor) Expensive and as I said a Zed is never going to be a quiet place is it, maybe get some cheap stuff like the brown bread and just try and identify where the problem areas are?

spursmaddave Posted August 4, 2013 Share Posted August 4, 2013 Just reread your first post, if it is trim rattle then soundproofing won't sort that.... what I did was get some thin draftproofing adhesive tape and put it in some of the edges where the trim touches the body Quote Link to comment Share on other sites More sharing options...

All depends on price! I doubt it will be cheaper than £500 incl labour and materials. Hopefully someone on here did it before and can give more answers to my request..
