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

 

well. in the 4th gens the best place is to route to where the PCU's wires run through the firewall, which means unbolt the computer set it aside and find where the wires are running in the firewall, there should be a rubber seal with enough room to run 4 gauge wire, and maybee even 0 gauge. hope that helps.
