I need a ham radios power line to go through the firewall. Pretty much the same as running an amp with a 25-30 peak amp usage. Regretfully the battery side of the cable is easiest to go through but I haven't taken time to look for a spot from inside the car. It's thunder and lightening right now like lots of the last 43 days of rain. Anyway I don't see me going from inside past the a/c on the passenger side unless there is enough space for a feeder line to be able to drop down behind the a/c to the floor after poking it in from the engine side. I've also wondered about the throttle cable lines hole for a power line. I don't know right now but just wonder if any other hams have gone the route already feeding their rig. It's a Yaesu FT-100D I'd like to run some times for ham and MARS.
