Review on 📢 Enhanced Whelen Airhorn Plus: Public Address Added for Advanced Functionality by Kevin Duhon

Doesn't say more For those wondering, yes it sounds exactly like a police car horn. Ignore YouTube videos that show it doesn't sound right. Just make sure you're using a good brand name speaker. I used a Whelen sa315P that I used from an ex cop car. Installation is easy if you have a basic knowledge of connecting things in cars. You really only need to run 6 wires, a floor speaker, a positive speaker, a negative and two wires to a momentary switch. Installation took about 3 hours, half of which was spent figuring out where to install it as the unit is larger than I expected. So if you are looking for an air horn without a siren, look no further. If you are installing on a 05-10 Grand Cherokee I would recommend installing the unit under the passenger seat as it suits me perfectly.
