so I want to install a system I my car and I want to run the power wire thru the grommet in the firewall right behind and a lil ower than the under hood fuse box... I have one bolt off but don't know how to get it the rest of the way out. any help would be appreciated

 

not necessary. there is a free grommet just above the gas pedal, behind the sound barrier, where a circular cut-out exists.
