Screaming Banshee - Loud Motorcycle Horns and Safety Systems is the easy way. Just connect the horn cables to it and a second power cable from the battery to feed it and boom.
It's not very pretty, though.
But a relay bypass is easy if you want to use any old horn. You connect the original horn cable negative and positive to a relay, so when you hit the horn button, it turns the relay on. Then you connect the new horn and a power cable to the relay so that it gets power when you hit the button.
The reason for that being that a big air horn sucks down a lot of amps. The stock horn button and cables aren't sized to handle a sudden 20 amp power draw.
I'm thinking of putting a couple of horns on mine. Literal horns, that is.
