I am installing a sounds system in my 92' camaro rs. I was wondering if anyone has done this. I cannot find a hole in the firewall to put the main cable from the battery back to the amp. Am i just not looking in the right place, or do i have to drill a hole in the firewall? thannk you

Is yours a manual or Auto? There should be a grommet or a plate where the clutch resivor should be.
