4g4ds with stereos help

hey you sedans out there that are running 8/4/2/0 gauge wire back to your amp... could you get a pic of where you ran your wire through your firewall...

of all the cars i have installed on, i could always find a premade gromet for passing wire through, hell, even the 4g hatches have one... but i can't find a single place on my sedan, so i just drilled, but i'm getting paranoid about it, so i wanna run it through an actual gromet...

just wondering, thanks...
