Review on 🔊 Enhance Your Truck's Audibility with the Wolo (845) Road Warrior DD Roof Mount Truck Air Horn - 12 Volt! by Randy Washington

Put this on a 2004 Mazda 6 (had to use some Southern ingenuity, L-brackets, zips, zip ties and a strong will to succeed) as I plugged it into a button off my main horn. So my wife can still honk when I'm driving or in the passenger seat, I can blow it up anytime! I love my air horn! I'll also mention that I also hooked up an old model 110 boat horn that I bought a while ago for an e-bike I installed. It has a slightly higher E pitch but sounds great with two horns in tandem!
