The only other way is to run it to a toggle switch, but then you have to turn it on and off every time you listen to the radio. If you forget to turn it of, you'll end up with a dead batt. Wouldn't recommend this way unless really nessesary. If you want to take the time, you can find and tap into the radio power wire that gives the radio power when the ignition is on. It's just easier running to the fuse box though.
