Review on 📢 Wolo Air Horn Big Bad Max 619 - 12 Volt, Black by Tommy Penn

I threw away the bones and ordered one of these and when it got here and I tested it before installing I was less than impressed and actually quite upset. It didn't sound like a video and it was very quiet. Realizing something was wrong with it I asked Revain for a replacement and when it arrived it was slightly better but still not what I expected. I played with it a bit, loosening and evenly tightening all the screws around the diaphragm, and the sound sounded better, but still not great. It was good enough that I wanted to give him some time. Today I had to honk a deer that was on the road and it sounded awful and almost silent. I chose this one, sent it back and received a refund. For those wondering, I installed it on a 2015 GMC 2500HD, first plugging it directly into the factory wiring. Thinking that maybe the voltage drop was enough to affect the output I connected it to the supplied relay. While it's a bit louder, it's still not very good and nowhere near as loud as a standard horn.
