## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy, Clean and fun for parades
*by M***Z on June 24, 2023*

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.

### ⭐⭐⭐⭐⭐ Reliable and Loud!
*by J***E on February 11, 2025*

I’ve had this for about a year and it still works great. Installed on my 99 jeep and put the controller inside of the center console and the horn sits where the ABS would be (if I had it). Very loud and works great for messing with friends or communicating on the trail!

### ⭐⭐⭐⭐⭐ Great product better than any other product for the price
*by S***N on June 5, 2021*

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.
