Wolo (419) Bad Boy Air Horn - 12 Volt , Black

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, connectors or relay socket. It does come with a relay, but if you have a relay for your horn on your fuse panel you will not need it. Throw the relay in the box you have saved all your other important widgets you'll never use.Upon careful inspection of the wiring of my horns, I quickly realized it would easier to ADD the horn to my existing horn(s) rather to replace one or both of them. I did a quick calculation of the amperage required to run both of the existing horns as well as the Wolo Bad Boy, and it was way less than 30 amp horn relay fuse on my fuse panel.I used suitcase connectors (http://www.amazon.com/3M-Scotchlok-Electrical-Automotive-Applications/dp/B0002BFZ7U/ref=sr_1_1?ie=UTF8&qid=1337450946&sr=8-1) to make the connections to the existing horn wires and crimped on the female spade connectors (also not included) and I was good to go. The entire installation took less than 20 minutes.The horn test from the drivers seat was impressive. It was not unlike the first test in the workshop, It didn't scare me this time as I knew what to expect, the ear ringing was much less, but still there. I was grateful there was an additional 10 feet of separation from the horn as well as closed doors and windows.Hopefully going down the road to our next adventure at 65 mph will lessen the horn blast inside the cab.Can't miss with the Wolo Bad Boy!

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 the car frame where you can insert the existing wire clamp to anchor this plus (+) wire lead.I purchased some 16AWG wire for a chassis ground (you will only need about 6" of 16AWG wire). I crimped a 3/8" female spade on one end (which connects to the minus (-) Wolo male spade). Then I crimped a 1/4" vinyl insulated ring terminal to the other end of the ground wire. Note: Attach both plus & minus wire leads to Bad Boy horn before securing the horn to the OEM bracket with the bolt included in the kit.I cut about 3/8" off the Wolo mounting bolt, so that the threads would not protrude so close to the radiator (this is totally optional). Next tighten the Wolo mounting fastener nut to secure the horn to the OEM horn bracket.I used the original bolt (that secured the OEM horn bracket) to secure the ground ring terminal to the car frame. There is an existing threaded hole in the car frame where you can terminate the ground wire [from the minus (-) lead from the Wolo horn]. See customer images for installation location.To insure that the Miata electrical system would handle the increased current, I replaced the existing (15 Amp) horn fuse with a 20 Amp fuse. The fuse box is located in the passengers' side of the engine compartment near the wiper fluid container. Note: The horn circuit is the same as the stop light circuit. It is indicated on the top of the fuse box as a "Stop 15A". See customer images for the fuse box & notations.Hopefully this will help other Miata owners to install the Wolo Model 419 Bad Boy Air Horn in your vehicle. I am glad that I took the time to do it, because I could not stand to hear that annoying little OEM horn any more. The Wolo horn is relative inexpensive and well worth the money when purchased at Amazon.com. It is normally $39.99 at Harbor Freight.New Parts Required Summary: (1) Wolo Model 419 Bad Boy Horn Kit, (1) 20Amp Fuse, (1) Approx. 6" long 16AWG wire, (2) 3/8" vinyl insulated female spade terminals and (1) 1/4" vinyl insulated ring terminal.Good Luck,J.

I purchased this for my Vicotry Cross Country motorcycle. The OEM "meep-meep" horn just had to go. The Wolo Bad Boy provides a nice upgrade to the stock horn.Installation:I purchased the Wolo MCHWK-2 Horn Wiring Kit along with the horn. That made the wiring installation simple. For the physical installation, I had to manufacture a bracket to mount the horn to the bike. I had a piece of steel sitting around the garage and drilled a couple holes in it. It turned out dandy.Function:It is loud. It sounds much like a car horn. It is SOOO much better than a stock motorcycle horn. That said, I was actually hoping that it would have been more obnoxiously loud. Even my large bike seems to be invisible to drivers sometimes, so I rely on the horn to get distracted/blind drivers' attention. It works. It is a huge improvement. It is no train horn, though.Construction:The compressor is metal (cheap steel is my guess) clad in plastic with the resonance chamber/trumpet area all of plastic. The "chrome" you see on it is just shiny plastic. But what can one expect for this price point? The stickers do not come off easily. Expect to be forced to use some Goo Gone or something similar to get all of the glue off.Conclusion:The only reasons why I gave this four instead of five stars are because I'd prefer it to be a touch louder (yes, I used the relay and power the horn directly from the battery) and I question how long it'll last. But it does seem to be a good product and, like I said already, it is way better than the stock horn.
