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

Extremely loud! Love it!

Great quality product and made solid! Speaker weighs almost 3lbs! Sounds are clear love the electronic horn and Yelp feature. PA is the radio selection playing around with it a little. Euro horn and hi-low are neat as well a little dorky if you’re in the US. Wiring tips. RED is + Black is the Ground or -. Your green wires are for the speaker as there are two green wires for it. All you’ll need is to tie back the other blue wire and yellow wire unless you want to wire the electronic horn in to replace your factory horn. Then just run the four wires through your firewall, most have a rubber grommet with wiring harnesses going through it! Then hook up red to + and black to - and your two wire speakers the. Your set! Well worth the $100 in my opinion hope this helps!

Most value for the dollars spent. Powerful speaker! Easy to install.

Works beautiful. The way I wanted it.

I love this thing! I’m driving around pissing people off daily it’s awesome. Super loud well-made just love it. I wish that it had different sounds on it like more silly sounds and I wish that it was easier to put together because it was actually a pain in the ass to put together very hard for my husband to put in my car. But other than that totally worth it.

Plenty loud and easy to install. Very satisfied with this product.

It’s loud... I have 120dB horn installed and it’s every bit as loud, if not louder... straight forward installation. (Power + relay + ground) The wiring is not long enough for the speakers or to bring from inside the cab all the way to the battery. (I installed a remote 12v relayed power source into my truck under driver seat... more than long enough power/ground wires for that)

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

Haven’t taken this off-road yet but we bought it to mess around in the woods. Super easy install. Speaker is plenty loud enough. Kids are super excited. Wired in easy with some flashing lights we had installed. I’ll find out in a week how durable this unit is.
