Hella Dual Air Horns

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.

Great info, been meaning to upgrade mine as well.

Great tutorial!

not sure if you'll see this because this is a pretty old forum but the amazon link is to dual trumpet horns different from the horns in your video. which hella horns exactly did you use in the video?
