I recently purchased a 2019 Honda Insight EX which i'm super excited about. Only issue? I cannot, for the life of me find any information on the installation of a ham radio. For those of you unfamiliar- think audio amplifier for an idea. Specifically i'm looking to install a Yaesu FT8900r, which is normally powered with 13.8VDC +/- 15% and idles at 0.5A draw and up to 8.5A transmitting. It's often not recommended to go through existing factory wiring but i'm not sure where else to turn. In a perfect scenario i'd mount direct to the 12v battery to reduce alternator whine but I'm not seeing any route to do that either. I considered an additional battery to power the radio but i'm not sure how I could safely recharge that battery if installed. Does anyone have any guidance/recommendation on how I should go about this?
