So... check local laws before installing on normal cars - security cars like mine - that is ok - The 12V 200W 20 Tones Police Warning Emergency Siren PA System is a powerful and versatile solution for emergency vehicles such as fire trucks, ambulances, and police cars. The system features a 180° design speaker that provides clear and loud sound, ensuring that the siren can be heard from a distance. The wireless remote handheld microphone allows for easy communication while on the go, and the two 10A switches enable control over the siren's various functions. With 20 different tones to choose from, this siren system is suitable for a range of emergency situations, making it a valuable addition to any emergency vehicle.

This is quite a bit louder than I was expecting, and has a lot of options. It has a mute button if you want to just pause the siren for a second (you literally have to if you want to hear anything!), and a push-to-talk megaphone type function which is really cool. It automatically silences the siren while you are talking.
