Works For Motorcycles as Well
Wolo® - Big Bad Max™ Air Horn
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
Wolo® - Big Bad Max™ Air Horn
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.

Very easy to install. Great loud horn everyone can hear from far away.

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.

It's actually much louder replacement for your original factory horn. Wolo model 619 had high quality and deep tone. Perfect to get the attention of anyone not driving the way you want them to. I think I'll by second one soon.
