Hello
I would to install a couple of different radios in a newer vehicle. But at this point I'm just doing some research. I'm curious if it's possible to run wires through the firewall of a 2014-2016 Suburban with out drilling any holes? But also of course to do it safely. I've read articles about empty/dummy grommets under the floor. I personally don't think that's the way to go. I also thought the factory's left empty or blank spaces on the firewall? I greatly appreciate any information.
