I looked at a couple loud horns and they said to add 30 or40 amp fuses. Would that be alot for high dbl horns? I had a group,2 or 3 adults?? and 3 small kids, walking across a 40 mph 4 lane street with a turn lane the other day and maybe they looked before starting to cross but crossing the last 2 lanes they didn't even pay attention. I had to slow down a little but waited till I got real close before I honked, scared em for a second, I want something to scare em for a minute or two. I could have been one of those idiots texting and a 6 or 7 yr old kid was the last one to the curb.
