I want to permanently mount my CB radio inside my center console. How do I power the radio?

I have a 2019 JLUM with aux switches. I have a Uniden 520 cb radio that has 1 black and 1 red wire coming from the back of the radio. The only power source inside the center console is a USB port.

I have three powering options and I'm seeking some feedback so I can have a clean install---(no showing wires).
  1. Solder a cigarette lighter plug onto the red and black wires of the CB radio and have that nasty cord run from the console to the dash (yuk)
  2. Hard wire the radio to one of the aux switches and snake the wire under the carpet up to the passenger footwell--uses a precious aux switch
  3. Power the radio with the USB port that's inside the center console (either solder a usb cable to the radio or get a usb-to-cigarette adapter)
I'm hoping I can do #3. Will I burn up my USB port? Will I burn up the CB radio?

I already do it the #1 way and it drives my OCD butt crazy that there's a wire running from the console to the cigarette lighter. #hidethewires

USB port is not a good idea.

Wire it to the battery with fuseson both conductors at the battery

The USB port only puts out 5 volts so that won't work, if you piggy back off the wires powering the USB port you may exceed the fuse amp rating.
As Harry said, directly to the battery is your best option. 2nd best may be wired into an accessory port in the fuse box, if one exist.

That adapter gives you only 0.8 amps. A typical Uniden CB uses ~1.7 amps for receive
