I run my radio(s) off of a dedicated power and ground wire fed from the battery. I have a fuse block up front and run the power
and ground wires (twisted) back to the cab and they work fine. No noise and it is a very stable voltage. If you want the power
switched with the ignition, add a relay powered off the lighter or something similar to trigger the relay.
