well Im' working on blocking out road noise from my car...

I was wondering, are there any sound deadening materials behind this panel?? its circled...



because I just finished the trunk with these sound deadening I found... the shop taht fixed my car never bothered to apply sound deadening material back in... anyhow there's still quite a bit of noise coming in... so I was wondering if there's any behind that passenger side panel...

it could just be the cheap sound deadening material I used.... heh.
