So I'm an idiot and I'm going to give everyone a small tip so nobody makes the same dumb mistake I did.
When you install the second horn, make sure you don't point it up. I just mounted it without even thinking about its orientation, and payed for it. The first time it rained it filled with water and stopped working
Luckily, since it is DC, all I had to do was dry it out and it worked fine. When I remounted it I made sure to make sure it was pointing down
