Chiefgroover Posted November 20, 2006 Author Share Posted November 20, 2006 To finish off, next time you buy tyres get Bridgstone RE050a, very very quiet, and outperform any previous bridgestone effort by a long way. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted November 20, 2006 Share Posted November 20, 2006 Did something similar to my S14, the voids inside above the rear arches are notorious for amplifying the road noise, so people tend to use the space for stealth sub installs and fill the space up with foam, or alternately use expanding foam, works quite well.

Glad someone else has worked on this too. Single most important factor is getting the voids air tight as possible, the better the seal the better the result.

JohnA Posted November 20, 2006 Share Posted November 20, 2006 Just thinking aloud here: Could there be a deliberate reason why these voids and openings exist? Perhaps for evaporation of condensation, air expansion after airbags go off, that sort of thing... I, too, find the supra's road noise annoying, but is it merely an oversight or last-minute costcutting? Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted November 20, 2006 Author Share Posted November 20, 2006 No reason, loads of german cars have them sealed. I have sealed them for 13 years now, has airbags etc go off, so you can do this with peace of mind that your safety is not compromised.

JL do 6" subs, I'm going to look into the price of a pair of these, as it could be an ideal solution for me. http://mobile.jlaudio.com/images/9313.jpg http://mobile.jlaudio.com/products_subs.php?series_id=23 Quote Link to comment Share on other sites More sharing options...
Kranz Posted November 20, 2006 Share Posted November 20, 2006 Good stuff mate! I have some lead lined NVH barrier foam stuff from where I used to work. Think I'll give this a go and see how quiet I can get it. Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted November 20, 2006 Author Share Posted November 20, 2006 Thats the best you can get for the "under the boot carpet" bit and arch liners. If you can get strong enough glue that can stick summer heat (grip fill?) it would be excellent on the outsides of the quarter panels too. I one used it on a 95 Celica at it was quiet as a mouse easting cheese!. Just no good for sealing inner skins or doors though. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted November 20, 2006 Share Posted November 20, 2006 Another cheap option is to use flashing tape, it sticks well and damps out noise and costs about a third the price of Dynamatt;) Quote Link to comment Share on other sites More sharing options...
JohnA Posted November 20, 2006 Share Posted November 20, 2006 ...or perhaps thermal underlay for carpets. Flexible, acoustically deadening, cheap too. I also use it to wrap hoses so they don't get heatsoaked. Quote Link to comment Share on other sites More sharing options...

[qimg]http://mobile.jlaudio.com/images/9313.jpg[/qimg] http://mobile.jlaudio.com/products_subs.php?series_id=23 To get the best from them you would need to make a very rigid mount and seal the quarter best possible. I have seen this done with fiberglass, which provided a rock solid mount and non flex enclosure. It was heavy but sounded super. The fiberglass idea would let you tune the volume. Might even go this way next time myself. O dear, another photo "how to" guide lol. Quote Link to comment Share on other sites More sharing options...
