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

This was installed by professional installer, Turned unit on and and it burned out. I should have expected it, low price yes but you get what you pay for.

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.

after being professionally installed, this unit burnt up and almost caught on fire. I sugesst buying a more reliable unit

With the instructions inside the box products everything is easier

It is very loud and easy to install.

Great

I bought it for the PA function, but its so quiet its almost useless. I didnt buy it for the sirens but they sound bad too. They dont sound anywhere near real. The thing is also incredibly bulky and barely has anything inside it. Only reason i give it 2 stars is because it has gotten a couple laughs out of my friends, but i totally wish i would have bought something way different. If i hadnt misplaced the box it came in i would probably return it. Nowhere near worth 100$

Great device, must know where you want to install. Speaker is heavy duty. Device gives options and sounds great once installed.

Many sounds in this little unit. Great bang for the buck. My son loves his.

Better than anticipated.
