Review: Nice system… - Works amazing and sounds great and loud, so far so good after 2 years
Review: 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.

## 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.

## Questions & Answers

**Q: Does it have the option to connect the siren to the vehiacle horn?**
A: Yes, it has a wire coming from the controller that attaches to the horn relay. there is a switch on the controller that if set to siren and you blow the car horn the siren will sound instead.

**Q: Is the siren speaker waterproof?**
A: The speaker is, but not the siren unit.

**Q: It keeps saying "hands free". Where is the part that doesn't require your hands??**
A: You can wire the siren box in-line between the horn button on your steering wheel and the horn relay of your vehicle to activate the horn function on the siren unit using the horn button on your steering wheel.  The hands free horn activation refers to not needing to take your hands off of the steering wheel to activate the siren horn.  Hope this helps.

**Q: how can an additional mic be added?**
A: The Unit has 12v running through each wire going to the radio. Keep that in mind if drinking around with it. Burnt out two amps trying to add some features

### ⭐⭐⭐⭐⭐ Easy install if you understand basic wiring!
*by M***Y on April 13, 2021*

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!
