Has anyone installed a louder horn?

[Gone in 60]

I test my horns every now and then just to make sure they still work, but every time I contemplate putting louder horns on my bikes, I think about how little I use them. Horns are used so rarely where I ride that when you do hear one, you look around to see why. I will say that the Royal Enfield skimped in lots of areas, but made sure the bike had two large, loud horns. Perhaps the culture in India is more prone to honking.

Back when 70s and 80s cars were prevalent in junk yards, I had a little cottage industry of pulling the four-horn setups out of Cadillacs and some higher-end Buicks. I believe the notes were A, C, D and F, and the sound was not so much like a train, but more like a cruise ship. I'd clean up the horns and build wiring harnesses with multiple relays to handle the power requirements, and sell the kits to my freinds. These are long gone, but I saved the last set and put them on Mrs. G's Honda.

Last night, rolling through the neighborhood, we honked at our neighbors, who were out walking their dog. They looked everywhere but at the little Honda to see where the sound came from.
