Review on 🚓 CARMOCAR 100W Car Siren Horn - 7 Tone Sound, Police Mic PA Speaker System, Emergency Microphone Amplifier. 12V Electric Horn for Emergency Vehicle by Paarvin Freedman

For a small, inexpensive siren system, it's surprisingly loud. The horn, siren and hi-lo sound great, which is what you would expect from an American fire truck, but the 4 call buttons are loud but sound more European. It's easy to install between the grille and radiator of my 05 Silverado, and the two power cables and quick connect microphone to speaker were easy to hook up if you're experienced with car wiring. Time will tell but for now I'm quite happy with this siren.
