WOLO 419 Dual Tone Air Horn

Installed this in a new Chevy Van. The van only came with a single, 2 wire horn which made replacement simple. I went the route of splicing new female wire connectors into the factory wiring and preserving the factory horn connector. For those not up for this challenge, simply cut the factory connector off and crimp on weather resistant female wire connectors. I had high expectations for a loud truck-like sound. No question that it is loud...far louder than the wimpy stock horn. It is not the deep, booming blast you get with multi trumpet air horns. Overall, I am quite pleased with this horn: compact unit, simple install, attention getting volumne/sound. As a bonus, it includes a horn relay (not needed for my application) which is not listed in any online listing I viewed.

this horn is sweet! The Mazda in which I installed it came with a stock horn that couldnt frighten a squirrell. Besides the small space I had to work with, installation was a piece of cake. One suggestion, make sure you have a 20-amp circuit. The first time I layed on the horn for a driver who pulled out in front of me I fried my 15 amp fuse.

This horn is great. I installed it in less than 5 minutes and the only portions of the install that slowed me down was figuring out what to do with the end of the old wiring and mounting the horn because the transmission cooler is right below the mounting bracket on my truck. The horn is really loud and no one expects it to come from my ford ranger. First time I used it was to wake a guy up at a green light that was texting on his cell phone. He dropped the cell phone and almost wet himself. Great horn for both getting stupid drivers' attention and just to play around with. I put pictures up of the horn mounted on my truck if you want to see it.

I got this horn for my girlfriend's 2000 Corolla a couple of weeks ago. She was tierd of the wimpy little factory horn. In a world of large SUV's and 18 wheelers she wanted her presence known. I installed this horn in about an hour. A lot of additional wires and connecters are needed as you have to make a ground for it (the factory horn grounded through the mounting bracket). The sound was a little higher pitched than what I had expected but a vast upgrade on the decibels. I know now if she needs to send a warning in traffic it WILL be heard. Good bang for the buck. I hope it out lasts its 3 month warranty (from date of purchase).

This is a great horn, hands down. Makes a sound like a Mack truck, and is compact, and easy to install. Just read the instructions. All of the negative feedback thus far is from people who either have no understanding whatsoever of 12v automotive electrical systems, or did not read the simple installation instructions. It took me 20 minutes to install this horn, and I even had to run a new wire back to the place that I decided to mount the horn from the old horn's location. This horn will pay for itself a thousand times over the first time it keeps that Chevy Suburban from running you off the road at night.
It's also good for scaring animals and small children, if you happen to be into that kind of thing.
