fox_racin4 Posted July 23, 2012 Report Share Posted July 23, 2012 deadening hardbord isnt necessarily a good idea because a CLD is inneffective really on wood. the whole gluing the hardboard to ur roof thing may work but considering how much more work it is over a proper CLD like damplifier pro i wouldnt look at doing that out of the gate worked fine for me.. its not very much work at all..

emperorjj1 Posted July 23, 2012 Report Share Posted July 23, 2012 right im not saying the hardboard support on the roof wont help with flex but the CLD on the hardboard is the drop in the bucket if you know what i mean.

SlamminBeats Posted July 23, 2012 Author Report Share Posted July 23, 2012 well i'll weigh my options. Something just needs to be done, i for see a major audible gain from this. Whether my numbers go bye bye or not, its a demo car mainly, i't going to take away that annoying roof noises. Quote Link to comment Share on other sites More sharing options...
emperorjj1 Posted July 23, 2012 Report Share Posted July 23, 2012 well there you go as long as your not 100% spl gains then id do plenty of damp pro on the roof. I was in the same position with my cobalt other then the noise (it had major flex but idk maybe bc new car it didn't make much noise from the roof at least) i did almost 100% damp pro coverage on the roof and added an addtional layer in the middle of the big flat patches. It took care of the noise and made it so it didnt look like my car was going to break in half anymore Quote J.

Chris Davis Posted July 24, 2012 Report Share Posted July 24, 2012 I damped pro'ed my roof last month and I have an audi a6 I did 2 layers on all of the roof with the exception of the pillars which even though I was told wouldnt be worth it for the area over its effect I still did one layer over it. I had no problems with fitting the headliner which probably could easily take 2 more or even one more and one of the luxury mats the pillars on the other hand I wouldnt be able to do another on the pillar but I could mat the trim pieces themselfs. And I feel you not wanting to ruin a new car take your time all pieces and test fit everything. Quote Link to comment Share on other sites More sharing options...
