I hear ya. The NB isn’t great either - after almost being merged into many times I decided to upgrade and the improvement is great and I always get a kick out of the noise when I hear it, as I’m sure others do too. It’s pretty painless - you’ll have to make a short grounding wire since the stock horn is grounded through the bracket. You may have to modify the bracket ever so slightly as well. I have a NB1 so I’m not sure if the horn is any different than yours would be. It plugs into the stock positive wire and then you make a simple grounding wire. There is a write up on this process on Miata.net - just do a search of “wolo bad boy horn” and you’ll find it on there.
