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

It’s worth it. Pretty easy to install, had to look up a couple YouTube vids but love it now.

Obviously not as loud as a siren on a fire truck or ambulance.. but it gets the job done. Still pretty loud! Side note: the siren is very waterproof!! Drove through many thunderstorms with it and it still works fine!!

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.

I like it and it works well, the only thing I wish it had was a man siren button

This was a pretty good value. Its louder than a lot of other units that cost quite a bit more that other guys at my department run. That said, I wish the siren would just turn on with a switch and not by use of the volume control knob. The other thing that could really be improved is if the rocker switches for the accessories would illuminate. Its hard to tell if my emergency lights are on if the switches would light up it would be easy to tell with just a quick glance.

This siren and speaker was very easy to set up in my truck. I love the professional and high quality feeling of the overall product. The mic has a nice weight to it and is not cheaply made. The mics cord is loose and not tight, being of rubber and not plastic, so it is easy to maneuver. The siren sounds are authentic American emergency vehicle sounds (although I have heard far better ones on a handful of Android apps and it would be great if this product had an auxiliary cable input). They are not like the Euopean counterparts. My ONLY issue is Ive learned that in colder weather it takes time to warm up, and that I have to have my heater running for that to even happen. Until then all that comes through the mic is static and white noise like crinkling paper when you push to talk. In spite of that, I would still buy another one of these and recommend it to others.

PROFESSIONALLY INSTALLED ON THE COUNSEL IN A 2010 CHEVROLET TAHOE I LIKED EVERYTHING THE LAMPHUS SYSTEM HAD ITS JUST WHAT I NEEDED FOR MY ON SITE EXECUTIVE SECURITY PROTECTION. THE THIN HEAVY SUPER LOUD SPEAKER WAS A PLUS WITCH COULD BE PLACED IN SEVERAL DIFFERENT LOCATIONS UNDER THE HOOD IN THE GRILL AND ETC.

Works amazing

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.

Seems like when the unit is on and I start the vehicle I hear static noise coming over the PA system from time to time or if its running vehicle is running time to time I hear its like pulling up to the gas pumps which is quite loud
