If you want to upgrade your horn and do it for not a lot of money, Fiamm Freeway Blaster is a good choice. Bolts straight on using the stock bracket, uses two stock wires and clears the forks and fender. It is louder than stock by a good margin. Not an air horn, but the best of the lower cost options. I own both. Air horns (Ear Cannon from Aerostich) requires a relay, wiring harness and sturdy bracket. It will wake the dead. Also requires space. The Fiamm gives you a good option for $15.00 Amazon or $8.00 from an Amazon retailer. The stock horn is ......well, a stock cheap sounding horn.
