i have a 96 i30 t and i have an audiobahn 15in sub in my trunk and when i play it, it sounds good but it makes an annoying sound right at where my roof and my back window meet. i have held it to see if it would stop and it did but i dont know how to fix it. any suggestions would be appreciated.

 

try dynomating the trunk, that should eliminate some vibrations, try maybe turning down the bass a little too........

 

Yep, Dynamat the trunk.

 

so dynomating my trunk should do the trick or should i dynomat my roof?

 

if you do the all of trunk correctly, should be enough.

 

thanks i appreciate it
