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

A lot of reviews said this was quiet. Its pretty loud as far as I can tell. The sirens do the job, but they have sort of a weird tone, which makes them not sound like the real deal as much. They work though and are very loud. I bought the second speaker size. UPDATE: Here I am about 3 months later, and the sound has decreased by at least 25% and the microphone is super static like every time you talk through it. Still worth the buy. It works just not perfect.

I didnt know how loud this would be but once installed it in my Police Interceptor I was amazed at how loud it was. Easy to install. I use it at car shows, car meets, and at Cub Scout functions. I sometimes use it to talk to other drivers on the road. Lol.

The push button on the microphone sticks

Very good product. Easy to install even if you have little experience. Wish it would be a tad bit louder.

Love my new toy horn. But have to be careful how I use it! Yes thats an old meter maid from San Francisco. Does a great job Doordashing now. Can always find parking! Installation 20 minutes

Works great is very loud and is clear when you speak out of it. Siren and horn work great also have used it a few times already!!

Put it on my golf cart. My neighbors are on high alert.

works great

Excellent performance at a great price

Came in quick and was really nicely packaged. We liked the fact that it was easy and the price was great for the quality.
