RFI on audio, agreed. Noise on DC, not so much. Routing is the most

Yes, routing is important. But what you're missing is that a major issue
is RF getting into the vehicle's computers, and the RF noise from those
computers getting into our DC wiring. I learned this the hard way with
my 2006 big Toyota SUV. Calling CQ barefoot on 20M SSB put the car's
computer into "limp-home" mode in the NV high desert. Had to disconnect
main battery terminals to reboot the computer to get home.
