SoundAlert 100W Emergency Police Siren Kit [118-124dB Slim Speaker] [2 x 16A Switch Control] [Hands-Free Air Horn] [PTT Mic] [Radio Rebroadcast] Warning PA System for Emergency Vehicle Trucks Cars

The shoulder microphone BARELY picks up any voice input. Aside from that the alarms & wails sound good.

The wiring coming from the actual speaker itself has corroded in under a year even with proper installation. Unless you plan on changing this out every 8 months I wouldnt waste your money.

Unit works great and was reasonably priced

Easy to install and use. very loud.

It’s loud... I have 120dB horn installed and it’s every bit as loud, if not louder... straight forward installation. (Power + relay + ground) The wiring is not long enough for the speakers or to bring from inside the cab all the way to the battery. (I installed a remote 12v relayed power source into my truck under driver seat... more than long enough power/ground wires for that)

Works as described, been installed for 3 months and still working great. Installed Fire Dept lights and was able to run them to the extra 2 switches on the box.

Its loud and will do exactly what you want. Totally not speaking from experience but the less smart humans driving around will pull over and yield to ANYTHING with a siren :) Having controls on the box and not the remote does make it challenging to use at times depending on where its mounted.

Easy to use . Install, perfect value

Really good for the price

seriously crazy loud over the cheap stuff
