Features

  • FORCEFUL - On crowded streets, where flashing emergency lights are not always obvious, the SoundAlert siren always gets noticed. Equipped with a 100W amplifier; wail, yelp, and hi-low tones; and an electronic air horn, this unit commands attention.
  • MORE CONTROL - Other systems give you the basics, our's gives you the best. With two 16 amp, on/off auxiliary switches, this unit is more than just an authoritative auditory warning device, it's the backbone of your entire emergency warning system.
  • HORN OVERRIDE - Finally, a siren system that focuses on your safety. Thanks to the integrated horn override function that activates your air horn with your stock horn button, you can keep your eyes on the road, and your mind on the task at hand.
  • RADIO REBROADCAST - Stay informed, even when your not in your vehicle. The helpful radio rebroadcast feature takes input from any other radio and routes it through your siren's loudspeaker so you can hear your GMRS, CB, or HAM radio wherever you are.
  • COMPACT POWER - At just over 2" thick, this extra slim siren speaker easily fits on your bumper or behind your grille, and with its street clearing 118 - 124 dB rating, it gets respect wherever it goes.

  • Easy, Clean and fun for parades
Size: Compact Speaker (118-124dB)
I ordered this as a fun little gift to use on parades or picking up family. It’s pretty loud but sounds quiet in the car. The wiring and instructions were very easy to follow. I did purchase a 40 AMP fuse to splice the power cable with. Instead of connecting to the battery directly, you can connect it to the fuse box. Along with some additional purchases that are needed for this job: heat shrink tubing, insulated wire connectors for nicer look and functionality, electrical tape, pliers, Irwin wire strippers or scissors, large and small zip ties for speaker harness and securing the wires, and some plastic saw cover that I used to put the wires in to feed through the firewall (it was easy for my old car, but it might be different in newer vehicles. Since this is my first time, I spent about 2 hours learning and doing all this. It’s best to work in a garage where you can take your time and not be bested by the heat, but be in a shade for those hot summer days. Overall, I’m happy with the purchase and the unit works as intended. ... show more

  • Easy install if you understand basic wiring!
Size: Compact Speaker (118-124dB)
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! ... show more

  • Great system
Size: Compact Speaker (118-124dB)
Product was easy to install. Made a little hole in my firewall fished the wires trough, install where I wanted the control box, connect the adapters, hook up the hot to the positive side on the battery, connect the ground, and put the 2 green wires to the speaker. After that you ready for use. It sounds really good, and the box is easy to use. I also crashed my car in the front and the System still worked and had no problems. ... show more

  • If you’re on the fence about this, just buy it. Very worth it!
Size: Compact Speaker (118-124dB)
Installed in about 30 min. SUPER easy install and I’m not even that familiar with electrical. It’s pretty simple to be honest. I was skeptical about buying this because the price was so cheap. Well lemme tell ya! ITS LOUD! I have the speaker installed underneath my F150 facing the ground (to help with the db’s) This is beyond loud enough for what I’ll be using it for! Obviously the sirens won’t be getting used but the horn/radio PA system are great! ... show more

  • Way better than anything else at this price point.
Size: Compact Speaker (118-124dB)
I’m a volunteer FF/EMT and needed a budget siren system. This thing is WAY louder than I expected, and everything feels very high quality. Installation wasn’t too bad. I appreciate the accessory switches as it allowed me to streamline everything though one box. Great work Lamphus!

  • Great system with one exception
Size: Compact Speaker (118-124dB)
The system was easy enough to connect and the siren functions all worked great. The PA function is ok, but doesn't sound quite as good as I thought it might. Also, I tried to connect to my radio's speaker wire (followed directions) and it did not work at all....got a loud, high pitched "noise" every time the mic was keyed up (even far away). I tried to use the volume adjustable screw in the back and it broke upon trying to adjust it. So, the radio speaker function simply won't work now (but it wasn't working anyway). Otherwise, the unit is good. ... show more
