12V/24V 100W Police Siren PA System Kit with Plug-to-Work Wirings Slim Speaker Handheld Microphone Warning Emergency Sirens for Vehicles Tow Truck UTV ATV Van Car POV RV

i use it on my water tanker so the projected volume is muffled by the large engine but I think this particular unit would be more effective attached to a car with less engine noise, but its a great quality product and very easy to use and install i highly recommend it except for use on a large big rig but even though I still use it effectively its more that the PA system isnt as loud when the truck is running everything else is sufficient or if on highway at higher speeds you will lose alot of loudness. but for incidents it serves its purpose

Has a hundred watt output public address system that’s plenty loud. A bonus is it has various police sounds that are most common in police vehicles. Some can be used but not all of them so check your states law on use of police siren sounds. However, the PA is for everybody and can be used with a wired speaker wherever one what’s it so it can go indoors or outdoors and basically anywhere a wire can go the speaker can go as it’s weather resistant. It doesn’t say anywhere what the speakers rating is but it should be somewhat protected from the elements. It’s a well made speaker that normally would be placed under the hood so a little protection is probably needed. The pieces and parts all fit together well and gaps are consistent throughout the setup. I didn’t find any cheap parts and all looked in new and good condition. The PA will be used at home games as well as the sirens will sound during made goals. All in fun of course. Four Stars ⭐️⭐️⭐️⭐️!!!

Great product. I have it mounted under the seat. Easy to use and hook up. Very loud and well worth the money.

Easy, quick install, could be a little louder.

Wasn’t loud enough
