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 out of 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.
POWERFUL BULLHORN – Built entirely from rust-resistant components and pushing 120-130 dB of intersection clearing power, our 100W bullhorn speaker works flawlessly with the SoundAlert control unit.

Easy, Clean and fun for parades
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.

Easy install if you understand basic wiring!
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!

Great product better than any other product for the price
I was a bit skeptical when purchasing this as I have never heard of this brand but I bought it anyway to give it a try. I installed it on my car and everything was pretty straight forward but my vehicle made it more difficult than it should have been. This product brings all the wires you need, siren, siren selector box, hardware, the removable PA microphone, and 2 solid brackets for both the siren box and the siren itself. Once installed, the sounds were extremely loud. Way louder than I imagined this product to sound. The large selection of different siren modes and the loud and clear PA system all work as advertised. As for waterproofing of the siren, we have had about 2 weeks of constant downpours and I have driven consistently every single one of these days yet I have not encountered any issues for the waterproofing of the siren. As for my favorite features of the this product, it would have to be the wide selection of siren tones along with the removable microphone which helps if it’s in the way. Overall, I am very satisfied with my purchase and I recommend this product to anyone that is debating this over anything else in a similar price range.

Perfect quality for price
I looked at the cheap plastic ones for $30, but after reading reviews, I decided against it due to the sound quality lacking.The quality of this unit alone makes it look very professional and the speaker is the heaviest part. It is a hunk of metal and I feel it is durable enough to withstand whatever nature hits it with. The handheld microphone is made of nice rubber and not cheap plastic like I thought it would be. The sirens and horns are very loud, but I do not plan to use them. I only bought it for the microphone and the sound is clear enough to be heard outside the car so I am satisfied.There is a lot of wires, but I only used the 2 green ones, and the red and black battery wires. The rest I do not need because I do not have any emergency lights nor want to hook it up to my cars horn.I’m sure there are louder speakers out there, but for the price, this thing is great!

Great system
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.

Loud
A lot of reviews said this was quiet. It’s pretty loud as far as I can tell. The sirens do the job, but they have sort of a weird tone, which makes them not sound like the real deal as much. They work though and are very loud. I bought the second speaker size. UPDATE: Here I am about 3 months later, and the sound has decreased by at least 25% and the microphone is super static like every time you talk through it. Still worth the buy. It works just not perfect.
