Wolo Customer Reviews
Wolo Big Bad Max Air Horn
2021-04-18
I installed 2 of these in my tundra and they sound great, definitely louder than stock and slightly louder than the train horn I had in the truck that stopped working. However the wiring directions are lacking. For my particular application I had to run both of the stock horn wires to the positive terminal on the horn and a separate ground wire on the negative terminal. The passenger side stock horn only had 1 wire which I also ran to the positive on the 2nd horn and another ground and it worked the same. For me it was easier to run 2 separate grounds for each horn but depending on your vehicle you could also run both negative wires to a single clean ground. Be sure to either use heat shrink connectors and or wire looms and electrical grease on your connections to keep the moisture out. You will also have to put in a higher amp fuse in the stock horn fuse slot. For the price these horns are exceptional.

Wolo Bad Boy Air Horn
2018-10-04
This horn far exceeded my expectations. It was easy to install and took 15 minutes or less. Looks great with all the chrome on my bike. Much louder than my OEM, and it will get the attention like I wanted it for. Scares the heck out of drivers beside me I see texting. (Just don't look at the driver when blowing the horn so they are confused and can't figure out who or what the horn was directed to). This was a great find. Customer Service was top notch. I would recommend this site to my friends and family without any hesitation.
