Review on 🔊 Wolo 846 Sputtering Chief Emergency Sound Horn by Jason Caldwell

Update 04/14/20: It has been overclocked to 350psi (highest setting of my CO2 regulator) for over 3 years. I would say the average usage is around 3 seconds per week in traffic and 5-10 seconds to state once a month. Still strong. At 350psi, that's a lot louder than a train. I once compared it at a railroad crossing and it sounded about 3 times longer than a train horn. My horn is powered by my CO2 setup set at 150psi and it sounds fantastic. Doesn't sound exactly like our FD horns but that's due to using CO2 instead of regular air, higher pressure and a different brand (we use Whelen). It's still clearly recognizable as an emergency horn and just as loud, even louder. People will definitely notice. Installation was ridiculously easy, I installed it under the front bumper of my Jeep XJ. I used a Kleinn 307 solenoid which matched the horn's chrome perfectly and it screwed directly into the horn's front hole for a pristine look and instant activation. The only issue I had was the 6 inch jumper hose that came with the horn. The fittings burst when I checked for leaks and I only had it at 60psi. It was supposed to have brackets, I don't know why they didn't. That's why I only gave 4 stars. Luckily I had a couple of clamps in my air hose repair kit and had no problems after that. To be honest, the hardest part of the installation was routing the 1/4" air brake line from the bumper horn, through the firewall, and then along the cab into the trunk while hiding it for good looks. under the panel above the doors. After that I just attached a quick disconnect to it in the trunk so I can easily remove it from my CO2 tank for air tools and refills. In general it's pretty simple. Let's see, doesn't really last.
