Works For Motorcycles as Well
As an avid motorcycle rider and realizing that the stock horn is very weak, I wanted to try out this horn on my bike. So many years ago, I bought this unit and installed it myself in less than five minutes. 12 Volt system, two plugs and one bolt - that's all you need. My first impression not having the engine running I noticed the extreme difference between this one and the OEM. During my first ride afterwards, I came up onto an intersection with a car driver trying to get into my lane. When I hit that horn that person hit the so hard and looked around for a bigger vehicle. I laughed and waved "Be careful and look where you are going" Probably saved both of us a bad day. This will definitely be mounted in my car as well. Quality is really good.

Loud and Deep
This is an excellent horn for the price. If you want it to actually sound as loud as a train you better buy one of those very expensive horns that has it's own compressor. This is a great replacement for the factory horn that is much louder. My truck had 2 horns installed above the drivers fender, so I spliced into it and kept one of them. This gives it a loud deep sound but also keeps the higher pitch from the OEM horn.

Deer Pay Attention to Hi-Lo
Wolo 416 kit complaints: instructions say to use 16ga wire, wire included in kit is 18ga, connectors in kit are 18ga. 20A fuse in kit is for 16ga and unsuitable to protect 18ga, insulated connector for side tab terminal of compressor (that instructions mention as important to use) does not fit into tab space. Wiring diagram does not mention that hi-lo_vs_both switch relies on case ground through mount point, and does not/cannot ground through ground tab on compressor end. I love the sound of this horn, and the ability to switch to a steady combined tone in town. Unfortunately, the quality control of the components doesn't seem great. Wolo does have phone tech support, but that conversation was not hugely helpful to us. My mechanic persuaded this Dec 2019 purchase (replacing a misbehaving much older Wolo 416 model) to work, so I can once again shoo deer off the road. Thanks for price matching.

Not Loud Enough
Sound that it does is fine, but useless as it is not very loud.

Great Little Horn
I replaced my dinky factory horn with the Big Bad Max horn. Now people actually respond when I give them a toot. Easy to install and pleasing horn sound. Loud enough to get attention without being obnoxious.

Worth It
Even though they are hidden in my fender still looks great. Installation was a breeze with the instruction book provided.
