i have 0 gauge running in my car but im not using it for anything. When i ran my wiring i saw that opening on the passenger side but its too close to the floor. I used the one on the drivers side that has a lot of factory wires going though it. Just push it aside and slide the wire though or cut a slit and run it through the rubber. if you end up just pushing it aside wrap the wire with some electrical tape to double protect it from the metal. if you want to do ur own grommet then your going to have to get a right angle drill and drill from the inside out.
