Query: nice and loud for a short time

Easy to install. This is loud, does have a tone similar to a air horn but after tow of these lasted less than two years I gave up. I don't know if its because I use my horn more than the average guy of its because its in my econoline grill and must get wet during a rain, but after a few years the horn sounds like a honda civic
