Review on 🚚 Enhanced Safety with the Marco Xtreme Blast Electric Horn - Italian Truck Accessories | Ultra-Loud Car Horn at 120 dB | Dual Compressor for Improved Performance by Mike Diaz

This horn is amazing. If someone interrupts me or acts like a jackass, I want them to hear my frustration. And boy - they ever can. Installation on my Ford Explorer took 6 hours - we had to remove one side of the bumper and install under the all metal bumper. It certainly doesn't take nearly as long with any other vehicle. This whistle sounds like a small freight train - and I'm in love! You need a wiring harness with a button - I had to buy a wiring harness with a switch for the horn. we bought them together. All I have to do is flip a switch and I can use that horn, or I can flip it and use my regular horn.
