I remember installing an air horn on my truck, and it was easier than I expected. Just make sure to have all the wiring and mounting brackets ready to go. Once you’ve got everything in place, it’s just a matter of hooking it up and testing it out. The difference in sound is seriously impressive, and it’s definitely worth the upgrade.
