Nice and loud
I bought 2 of these horns. One for a scooter and one for a Honda Goldwing. For the scooter, because of space constrictions I had to separate the air pump from the horn and mount each piece in a separate location and reconnect with vacuum line after adding a hose barb to each piece. Goldwing install mounted great. I mounted it behind and above front wheel fender in front of the radiator in the blank space between radiator halves as far up as I could. I have it turned vertical with horn opening on the bottom facing forward and it blocks very minimal air flow. I had to epoxy 2 strips of stiff closed cell foam to the horn, 1 above and 1 below the round chrome looking piece so that the back was flush and kept pressure off of round piece.Then I used heavy duty zip ties around frame piece in between radiator halves. 600 miles on Goldwing so far and all is great. And it sure is a BIG sound coming out of a little scooter. Makes me laugh. For both installs I left original horns hooked up as well so you get 2 different tones which makes it that much more noticeable. The horn itself works great. i purchased additional relays after reading about early failures with included relays. Just as a test for the Goldwing horn, I connected it to original horn wiring and then 2nd test I wired correctly and connected it straight to battery with the relay. It is quite a bit louder coming straight from battery with relay. And this is also the correct way to install it as the stock horn circuit is not designed to pull the power required for the pump. Hence, the quieter horn. I have read that some just use stock wiring and all is good but the relay install gives you more "bang for the buck".

Nice Sound-Easy Installation
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. Anderson

Great horn, but disappointing customer service from Wolo
I bought this horn to use on my dirt bike (motard style). Wolo advertizes that their horn will fit any bike, but it was very difficult to find any place to mount it on a dirt bike, as the horn is quite big. I emailed Wolo and asked for help about where to mount it, and they weren't very helpful - just said that my installer would have to find a dry place to mount it. I finally decided to mount it over the headlights. I then emailed Wolo asking for advice buying or making a rain shield. They didn't answer any of my questions about what materials to use in a rain shield, but mentioned a company called Metal Arts, but when I did an internet search, nothing came up. I emailed Wolo again, asking for a url or email address for the company and they gave me a phone number for the company. Since I live in Thailand, I wanted to contact the company by email, so I emailed Wolo, again asking for that information, but they never answered my final email. I finally designed a bracket and rain shield my self (the bracket from stainless steel, and the shield is an old helmet face shield). The horn is excellent - very loud, much louder than even the horns used on cars here in Thailand, so it really gets other drivers' attention on the highway. I had a switch installed so that I can switch back and forth between the Wolo horn and the original horn, so that I can use the quiter horn in town and not cause someone to have a heart attack! The relay went bad after a couple of months (the mechanic who replaced it says it was a cheap Taiwanese relay.) I've been using the horn for 9 months now, with no operation problems from the horn itself.

Let people know you are there!
Okay so the scooter I ride is a honda ruckus and very small. After all my mods its now also low so its hard to be seen in this scooter. I decided to go for a LOUD horn and I found this on Amazon and .... Add to Cart! Pruchase with Prime BAM! 2 days later! So I installed it and it was pretty easy - the instructuons was pretty clear and WOW is it loud compared to my "toot toot" baby horn. PROS: PEOPLE WILL HEAR YOU Install is pretty easy - the relay wires is pretty easy to follow with the instruictions. You just have to find aplace where it fits. It does dim my lights when I use it but its a scooter - what do you expect. CONS: PEOPLE WILL HEAR YOU but look for a 18 wheeler that honked , not the little tiny scooter Does not come with an inline fuse for the power (Recommended to do this) I was to peel all the stickers off because it is visible. If you have a bike with fairings then no problem, naked bikes it will probably be a bit harder to hide. This was a good buy and I think it will save at some point in time. If it does ill add to this review. The video attached is to my friend when I got the horn installed. I giggled like a schoolgirl.

Bad Boy 419 + Big Bad Max 619!! Loud and simple train horn sound with a tank setup!!
Installed the Big Bad Max 619 & the Bad Boy 419 on my 2005 Dodge Ram 1500. My truck had dual tone horns from the factory at 420Hz and 510Hz. The factory horn wasn't all that bad, just a standard horn and left some to be desired for a full size truck. I removed the stock 510Hz horn since the Bad Boy 419 is a dual tone horn with 530Hz and 680Hz. This left the two wires I spliced to trigger the two relays for the new horns. With the total of three horns and 4 tones; Big Bad Max 619 @ 320Hz, Stock @ 420Hz, and the Bad Boy 419 @ 530Hz and 680Hz...this setup is surprisingly loud for a relatively simple setup if you're good with wiring. No, it isn't a $500 Air Horn w/ Tank and Compressor setup, but it's close enough for me. It has a good range of Low/High tones and sounds like a 4 tone train setup just a little less dB and a lot less money, space, and time to setup. Total cost for horns (which both included relays) and 2 Wolo wiring kits was about $80. I used some higher quality ring terminals at the battery and soldered connections vs crimps. Mounting these over sized horns proved a little more tricky than I planned for but nothing too bad. The horns only have one mounting point and they are 2-3 times the size of most horn giving you few options. Overall, either horn by itself was louder than stock. The combo of the 2 together was awesome. Leaving the stock, plus both Wolo horns was everything I was wanting, and we'll worth the $80!

Not impressed
I got this horn to replace the mechanically damaged OEM horn in my F-150. Install is easy for anyone with a little mechanical aptitude -- you can pretty much bolt it to anything. Given the item description and the first page of reviews, I expected this thing to sound awesome. I should have read the next few pages of reviews. This thing does not sound "like a Mack truck". It doesn't even sound like a Nissan pickup. I would definitely characterize it's tone as "weep weep". It's almost more of a whistle than a horn. The worst thing about this horn is that it has about 1/2 second spool-up time. That means that when the horn chirps when you lock the doors and the like, this horn doesn't actually sound and all you hear is the compressor start to spool up and then stop. You can't chirp the horn from inside either -- like to politely remind the car in front of you that the light is green. The only thing you can do is lay on the horn like a jerk. Even worse, if you actually need the horn, often you don't have 1/2 second to wait for the compressor to do its thing. Long story short, I'll leave this horn in the truck to pass state inspection next week, but after that, I'll be replacing it with something more appropriate to the size of the vehicle and more importantly, something that makes a horn-like noise as soon as I hit the button.

Decent horn. Miss my old one.
Due to some comments, I have decided to take out my instructions for installing this on a 2007 Toyota corolla and instead will tell you that this simply ...works. I installed it 12/12/10 and it is now 5/06/12. Pretty good for a DIY project of mine. I suggest taking it to a professional however as there is some truth in the comments about experimenting on your own. This horn is made for 12-volt vehicles and USES THE CAR'S EXISTING HORN WIRES!!! This is soo important to keep in mind as it will save you the pain in your arms and wallet from thinking you may need to install a new, bigger gauge, wiring system in your car. The horn replaces the OEM horn in your car and usually will use the same size hole drilled in the frame, again you don't need to improvise or drill a new hole. I personally, however, used a zip tie and connected it through a random hole in the frame to ensure there would be no wiggling of the Wolo horn and eliminate the chance of the bolt loosening from friction. Quite honestly, it took me over 20 minutes to install this horn. Actually a couple of days because I did not know anything about cars. And in addition, my walo horn is kinda louder than my oem one. I actually miss the crispness of my previous horn more. But whats done is done and this horn sounds good over a period of 2-4 seconds. Quick honks or taps and it's kinda not that impressive sounding in my opinion.

Louder than I thought!
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!
