anyone know where the hole on it is and is it big enough to fit 0 gauge without drilling? i heard its on the passenger side. and i just got it so i havent had time to take it all apart to see.

I believe you are correct there should be something you can go threw on that side. Check for any grommets that have nothing in them as well.

checked for grommets, didnt really find any.

there is a plastic circle thing on the top right under the glove behind the kick panel but im not completely what its going through there. i'll look there when i get home and see if i can drill behind there.
