Has anyone here took out the rear deck speaker covers?..
Im running JL10w6's and sometimes that cover rattles when it bumps!..
I wonder how i should fix the problem..does anyone know~ without using dynamat~

 

I have... You have to take the seats and the centre console out, then remove the clips and pull it towards the front of the car. It sounds like a lot, but the whole thing takes about 5 minutes. I posted a whole DIY at some point (with pictures). It's in this thread...https://g35driver.com/forums/g35-sedan-v35-2003-06/97226-rattle-rear-parcel-shelf-possibly-seatbelt-mechanism.html
