I am putting a 2 channel amp in the GS for the 6X9's. I need to run a power to the amp, and don't want to cut things up. Where is the best place to run an amp wire through the firewall on a 70-72 GS? o No:
About midway across you will find a rubber grommet used for the heating & fan wires. Look just below the regulator. Might be room there to squeeze another wire.
