Just did the Hella dual air horn upgrade, wow, now it's now a SUV level honk! I didn't realize it was an air horn until I installed it. Now I can actually hear the horn...
The set below didn't need anything else (i.e. grounds) except for an extra 10mm bolt, washer, nut from Auto Zone to mount the second horn on the opposite side of the frame.
