Review on 🔊 Wolo 846 Sputtering Chief Emergency Sound Horn by William Sanchez

This horn is ridiculously loud. I installed it with the following add-ons: Viair 20007 2 gallon 200 psi constant power auto air compressor, Wolo 804EV electric solenoid valve. I lower the horn pressure to 60psi because the diaphragm wears faster at higher pressures. At 60 psi and 100 feet away, it still makes you jump! I installed it under the hood and Chevy 07 1500 4wd. Fits tight but works great. The kit included all the necessary screws/fasteners and even had a piece of hose with connectors. The only disadvantage. You'll need earplugs if you're standing next to it when you turn it off.
