Review on SoundAlert 12V 100W Police Siren PA System: Slim Speaker, 118-124dB, Handheld Microphone, Hands-Free - Emergency Siren for Vehicles, Truck, UTV, ATV, Car, POV by Alex Barnes

I want to use it mainly for the PTT function, which is the only function that is not very loud. The sirens and horn are terribly loud and my neighbors can attest to that. They also told me that they can hear me from outside their home if they use PTT but if they're driving over 15mph and it's on mute, especially if the person you're trying to contact has windows open and /or the radio is on. Car. Please note that if you connect the radio function to your car speakers, whatever is loud on your stereo or Bluetooth will play louder than PTT, but after a few minutes it gets pretty 2002. I'll update when it does breaks or when I add light to additional (fusible) switches.
