I am trying to run the power cable leading to the amplifier in my car but can not seem to find a hole or firewall to pass the wire through. My car is a 91 Toyota Tercel. Please and Thank you
The Tercel will have a couple of un-used holes that are covered with black solid rubber grommets. You can poke a hole through one with a pen or screw driver and just push the wire through. You should find these holes one the left and right symmetrically, and they will be near half way down, but closer to the top than bottom. If you can't see them, maybe you can feel for them.
Drill you a hole in the firewall where you know nothing will be in the way on either side, then install a rubber grommet in the hole so the wire wont rub through on the metal.
Make a new one. Use a drill bit the same size as the wire. They also sell firewall grommets that will prevent the wire from cutting.
