Check out truck stops. Get you a good semi horn with a powerful compressor!
I used to have a old 84 F150 with 2 air horn's from Semi's that I bought at a junk yard for $50 total. Talk about LOUD. I scared quite a few people with that thing!
These are all they're reported to be and the price is right.
True air horn with no air tank required, and 139 db of resonant dissonance.
My install was single horn based, but I don't see why one couldn't just splice into an existing relay fed factory horn wire and run this along with the stock horns too.
Harbor Freight sells the WOLO "Bad Boy" and it's a close copy of the Stebel horns. These are two channel horns, one high pitched (way above C#) and one slightly lower that share the same compressor. I put one on a Suzuki Volusia cruiser to replace the weak oem horn. *NOTE* these aren't the big diesel truck type sounding horn, these are the Ferrari type horns, very high and very loud, impossible to ignore. Actually thought about adding a second one to make it even louder. The best thing is the size: very small, about 6" x 6" x 6".

Hmmm.. That might work for our golf cart we use on a construction site. They require us to have an amber strobe light, a backup beeper, and a horn. Almost everyone has a little "meep meep" type horn. I want to put something on there that will make people turn a look!
Reminds me of a dump truck I saw a couple of weeks ago that had a triple air-horn mounted below the driver door (on the battery box ?) which put it at most car's roof level or so. They were angled back too.... Made me wonder what the *legitimate* point was.
