I have a dual tone Bad Boy Wolo on my Heritage. It is loud, gets attention, and is the only HD I have that I really like the horn or use it.
I added the Black Wolo horn on my Cherry but on the other side. Just fit better. Comes with a relay. I ran the Wolo in parrallel with the stock horn, so both sound (of course you can't hear the stock horn over the Wolo). You need to pick up 12 volt power down from the cables behind the left side cover.
The Black Wolo horn on the right side. Not very noticable. But yes, it is loud.

Yeah its been a while ... but I think I could wire up a bosch 12v/30a car relay. ... Im a network engineer by trade and took a 1 year electronic class a loooonnnnng time ago.
Just easy if there are pics.
But yeah, Ill probably just go for the Harley horn if its plug and play. Im 55. If I have extra time, I want to be riding not wrenching ! ... getting a little lazy too !!!
There are ready-made kits with everything you need. Still have to run the wires, but it's a one-click solution for any horn that draws too much power.
If you are cramped for space, the Denali Soundbomb has a version
that is split (horn/compressor) so you can locate the small compressor
someplace inconspicuous. https://denalielectronics.com/horns
FWIW, all of the compressor style horns will require a relay.
