James Bolen Jr: I've bought 3 of these, one for my XS1100, one for my 150cc chinese scooter & 1 for my cadillac. They sound awesome & loud! Not obnoxious. Make sure to use the relay included. in the kit. Just hookup your 2 original horn wires to terminals 85 & 86 on the relay. You will need a piece of 14 or 12AWG wire & 2 female terminal connectors to go from terminal 30 on the relay to the + terminal on the horn. the other terminal connector on the horn goes to your chassis ground, or anywhere metal on the vehicle. Then you will need another piece of wire with a female terminal connector going to the + side of your battery. Make sure to put an inline fuse on the wire going to the battery.

Fleet tech.: This was easy to install on a Sprinter van, and easily triple the sound. They really understate the improvement and personal satisfaction you will have when the first vehicle cuts you off.
Hint - hope it's a convertible BMW!

jose m.: Me gustó bastante, toca el claxón muy fuerte e inmediatamente te ven. Algunos se enojan por que les tocas el claxón y se quitan inmediantamente y más cuando están estorbando. Muy buen sonido de camión.

John Chapuis: This model came with no wiring and that made the job longer to fit.

Joe: I have an 35' RV with standard car horns. The horns (yes, the RV had two) were just not loud enough. Then the research began. I shop Amazon often so I started here. I did not like the decible rating of the electric horns so I looked at the air horns. They seemed robust enough, but the installation was going to be tricky under the front bumper. AND they were quite a bit more expensive than the electric horns. Then I found the "Bad Boy" from Wolo.
I was a little concerned about the quality based on the price for a self-contained air horn, but with Amazons no questions asked return policy, I decided to give this horn a chance.
You know the feeling you get when you first get something delivered? You can't wait to try it out. I have a 12v 25 amp power supply in my workshop I use for various projects and decided to give this unit a test blast in a confined space. DO NOT UNDER ANY CIRCUMSTANCES DO THIS WITHOUT EARPLUGS!. This short one-second blast scared me (seriously) and set my ears ringing for at least 2 hours. At that point I knew I had a winner.
I set Saturday aside to do the installation. As other reviewers mentioned, the horn DOES NOT come with wire,...

J. Anderson: I'm glad that I replaced the OEM horn in my 2000 Miata with the Wolo Model 419 Bad Boy Air Horn. The OEM horn sounded like a bicycle horn & wouldn't scare a child. The Bad Boy has a louder two tone sound, like much larger cars and you will not be ignored anymore.
The only difficult task was removing the existing OEM horn & bracket. I had to remove the Miata grille (screen) and one passenger-side headlight bolt to gain access to the OEM horn, mounting bracket, electrical wire & wire clamp.
I used the previously removed OEM horn bracket, after drilling a 1/4" dia. hole (near the bend in the bracket)for the Wolo Bad Boy horn kit included mounting bolt. See the customer images for approximate hole location & installation photos. I mounted the OEM horn bracket with the existing bolt on the radiator mount. The Bad Boy horn tucks nicely tucks in this area and is easily accessible. See customer images for installation location.
Wiring-I used the existing OEM wire & clamp. I cut off the old wire connector & then crimped on a new 3/8" insulated female spade terminal. This wire lead connects to the plus(+) Wolo male spade. There a existing hole in...
