I'm installing a Ham radio transmitter in my Model X and wanted to know what's the best way to power it. I understand there is a 12VDC power source in the frunk, but don't know how to access it, nor do I know how to get the wires into the main cabin. Is there a safe way to cross the "firewall?" I haven't bought the radio yet but I'm looking at one that will put out 50 watts or more (perhaps as high as 100 watts). I understand the console-mounted 12VDC cigarette outlet has its current limited so it might not be the best choice when transmitting on full power. I'm mounting the antenna on either the lid or on the spoiler and using a base-loaded Diamond Antenna K400CNMO mounted on a Diamond RR-72BNMO. It's short enough so as not to interfere with the garage door or hit low-hanging fixtures in other parking garages. I'm open to suggestions there too.
