Horn upgrade suggestions
 

I'm looking to upgrade to a louder horn from my stock wimpy sounding horn. What are some horns that are really loud. I prefer electric over air due to the weight factor. I have heard of Stebel horns. They are usually 139db range. Are there louder ones out there? Thanks in advance

i think 139 is plenty loud, i think they say that at 140 you can experience immediate and permanent hearing loss. wouldn't surprise me if thats why its 139 and not higher.

it also helps at where it is located. Currently i have one of the 3 trumpet"big rig" horns, it's load, but not when the hood is closed. You can hear it on the highway, or make co-workers crap themselves when they go under your hood at work

I had this Dixie Horn for about 5 years and it finally quit working. The air compressor would run, but not sequence properly and 2 of the horns would no longer make any sounds. I used this horn in my 1993 Chevy van and my 1971 Dodge Demon. As soon as I bought my Metro, I installed it, but removed it when I discovered it was broke.

I am not one to let a $60.00 horn go in the trashcan, so I modified the horn so it would at least be use-able. I removed the top cover and removed the rotation diaphragm and springs and then used silicone to seal the horn and also block off all of the ports but one................

I then let the silicone dry and used the longest (loudest) horn and hooked it to the single port. I now have a very loud single tone air horn in my Metro to replace the cheezy horn it has. It sounds like a big rig horn.............

I got a junk yard horn from a Buick Electra to put on my old Datsun. It sure turned some heads.

The higher sound level horns are also generally higher pitched.
So while being loud,
they don't get much attention.
There are a set of horns at the auto store from WOLO (and others)
that are 125 dB.
One horn is high pitch, the other low.
Together they have that great old Buick sound.
Mine are wired so the high pitch 'beeps' normally,
and they both go on if the brakes are applied.
This gives the big sound when needed,
but the friendlier high pitch when you want to just beep Hi.
I've done this on my motorcycles and in my car.
works great and that dual tone gets noticed.

Tech note,
older people don't hear the hi pitch very well,
it takes twice the power to raise the level 3 dB (ie 125 to 128)
but it takes 10 dB more to sound louder to the ear.

Hi,

The Fiamm horns are pretty darn loud, IME.

Harbor Freight sells some pretty inexpensive air horns. The horns are made out of PVC. I think they are rated at about 135db. I have one on my 1988 Escort, because the factory horns weren't very loud and sometimes the horn button in the steering wheel didn't work so I reworked it with a $25. air horn.

I took the horns from an older Cadillac.
Two electric horns mounted on the radiator support behind the front bumper.
The original wiring wouldn't carry enough current to operate them both at the same time so I wired a relay from the old wiring.
Horn wiring to operate relay.
Relay directs battery power to the horns.
Work good, last long time G.I.

I met a dude that had a train horn on his civic. It turned heads half a mile from him.:D
