crunkjuice1 Posted April 22, 2011 Report Share Posted April 22, 2011 This thread will be on behalf of my friend that owns a mazda 3 4 door car. he recently bought my two 12 type R 12's and fosgate P1000-1bd. Since then he has suffered from alot of trunk rattle that goes into the cabin. We just got done using a bit of damplifier pro but just to be on the right page we used one layer of it on the majority of trunk but now it seems the air is trying to find another way out of trunk. Will this be something he has to learn to live with or something he can tame? on both sides vibration travels forward up pillar but flexs the most on rear side panels travels a quarter of the way up arc over rear doors on both sides equally advice needed please.

baaudio Posted April 23, 2011 Report Share Posted April 23, 2011 you could try finding a hole that goes from the trunk into the pillar and fill it with expanding foam or cover it with deadener Quote Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k Link to comment Share on other sites More sharing options...
Second Skin Rep Jon Posted April 23, 2011 Report Share Posted April 23, 2011 Do you have pics of the areas of the trunk that have been treated? Later, Quote Have a question about Second Skin? E-Mail me! Link to comment Share on other sites More sharing options...

crunkjuice1 Posted April 23, 2011 Author Report Share Posted April 23, 2011 its metal we DP most of trunk from inside under glass working towards trunk lid then did as much as possible on trunk lid. the lid didn't really have large areas to cover more like a bunch of patching. It seems to me he has to add another layer over what we did and then gut the trunk to get to the areas in pics to deaden those spots. Pics of what we did are real close I don't think they show much but here they are coming from upper inside of trunk outward covered this too under glass same area as last pic but covered up with DP doin work get an idea of trunk design From there on finished up the rest of trunk lid and had two sheets left but it was late and we threw subs back in car wired everything back up and played a few songs and there is a difference but like I said he will need another layer. The pic of me breaking my back where my left elbow is, is where you can get to the first two pics I posted but he needs to save up to get more DP. That car body is flimsy as hell and from the bit we did do I think that the bass is now diverted to the weaker areas since the DP is doing what its supposed to do.

Second Skin Rep Jon Posted April 23, 2011 Report Share Posted April 23, 2011 Yeah from the looks of it he's going to need to tackle those rear quarter panels to prevent this issue. And basically what you said is true, he's diverted everything to the areas that are untreated... so you'll get different rattles and flexing. Later, Quote Have a question about Second Skin?
