SoundAlert 12V 100W Police Siren PA System [Slim Speaker] [118-124dB] [Handheld Microphone] [Hands-Free] [2 x 16A Switches] Warning Emergency Siren for Vehicles Truck UTV ATV Car POV

Awesome toy for grown folks. Its ridiculously loud, fun as hell to let people know The light is GREEN! in traffic HAHAHA!!! You may want to check you local laws as the siren and horn option may get you into trouble... big trouble. Also install was ridiculously easy.

I love this the flat speaker makes it easier to install . Installing is super easy ..

The best item number one

This is not a toy! This is professional level sound. I tested it with a battery on my back porch and neigbors came out!

had it installed! No way i would be able to do it myself. then he had to find a place to put it. These people i purchased it from were very easy with replacement after speaker blew out on first one. havent used siren in current one dont want to to blow out.

It’s really loud for being the lowest of the models they offer. I found this out by turning the siren on and proceeding to blaze through traffic and red lights until I found a lonesome officer on his phone while driving so I proceeded to pull him over and place him under citizens arrest until a Pizza Hut delivery driver showed up to take him away in his 2002 Honda Civic. Moral of the story... nobody can out pizza the hut.

OVERALL The control box seems to be larger than it needs to be, causing a mounting issue. I was able to find a place, but not where I initially had hoped to mount the unit. Buttons, switches, and knobs seem very sturdy. Wiring is great - easy to hook up if you have a little experience with automotive electrical systems. The backlit selected Mode titles are a plus, but not having any other functions/switches backlit is a bit of a bummer, especially with how small the volume indicator is on the knob. HORN The Horn is why I bought the unit. Lamphus includes an optional jumper wire that you can connect to your vehicles horn circuit so that pressing your vehicles horn button engages the Lamphus Horn, which can be quite loud. Its a bit of an electric air horn sound, like some of the Police cruisers use. When the control box is turned off, the Horn feature will not work, and when the unit is turned on, the volume knob controls the volume of the Horn, whether using the jumpers or pressing the momentary manual switch on the unit. SIREN I disabled the siren functions because I dont want or need them. I did try it all out during bench testing of course and found the sirens to be toyish. The tones go too high and for too long - they just dont sound like any emergency vehicle sirens. Fine with me - I didnt want them. I disconnected the brown wire behind the momentary on/off/momentary on switch so that now only the Horn function works and not the momentary Siren. Also, I put a screw directly into the face of the device next to the Mode selection knob in such a way that only the Radio and Standby modes can be selected. PA The PA works brilliantly. The volume control which also turns the unit on, controls the volume of the PA as well as the volume of the horn and siren. The microphone unfortunately is permanently attached to the device not allowing for easy replacement or disconnecting for any reason. But the handheld mic seems sturdy, the switch works fine, and the microphone seems to pick up well. There is a very brief delay once the PTT button is pressed until it transmits. RADIO Mode There are two white wires which can be used optionally. They can be hooked up to any devices audio output such as a CB radio, Ham/amateur radio, or iPod, etc and broadcast over the loudspeaker. The volume is controlled solely by the external device (ie: CB, Ham, iPod), and not by the Lamphus system volume. When Radio mode is selected, any signal input into the white wires will be broadcast at the devices volume level regardless of Lamphus volume level. The Horn and Siren switch can be used and the PA can be used during operation in this mode and it will momentarily cancel the input signal. CONTROL 1 and 2 These are two basic switches. You can run a light bar or any other 12 volt device using the supplied wires running from the main harness. LOUDSPEAKER The speaker seems very sturdy and the low profile allows for many mounting locations. I mounted mine between the grill and radiator so that it faces forward but is hard to see from the front of the vehicle. A typical cone shaped speaker would have had to be mounted in the engine compartment or somewhere under the front bumper.

This is a serious PA system. I dont have prior experience to compare it to, but the speaker itself is very heavy-duty and the instructions assume you know how to do automotive mounting and wiring. I knew nothing going into this project and it took me all day to install on my own with google/youtube. The speaker is so heavy, you really need to find a solid place to mount it. I ended up putting it inside the bumper of my F150 just behind the panel that holds the license plate. One thing that disappointed me was the lack of installation hardware. I ended up buying a new 1/4 drill bit to get through the metal (cobalt coated or something). I also had to go to Home Depot and buy 1/4 inch bolts, washers and nuts. I did all 4 mounting points because of the speaker weight. Wiring wasnt too hard, and Ive never done anything like this before, but I only did the basics and will find the stereo wiring later. It is LOUD! The honk, siren and voice projection are awesome. Im very pleased.

this thing is awesome the instructions were very specific and to the point and I had it installed within an hour very cool product

Now I bought this only because my car horn doesnt work, I cant find its fuse or relay so I got this, this is fun, talking to the PA using the siren but use it wisely dont go In public use it to get around traffic and acting like a cop, I use it out in the road as a horn, at my property I use it to troll around.
