Review on LAMPHUS SoundAlert Police Air Horn Kit 12V 100W [Slim Speaker] [118-124dB] [Hands-Free] Train Truck Siren for Vehicles Truck UTV ATV Car POV by Kobby Cagle

I ordered these to replace the horn on my Dodge truck. It still worked but only had 1 horn and sounded pretty weak. I decided to buy it because the sound of the electronic horn catches people's attention. I was looking at a similar product from whelen but would cost between $200-$250. Installation was easy, I used the included switch to use the horn button on the steering wheel and kept the option to use my old horn. I brought a grey, powerful Lamphus horn and installed it behind the bars of my truck. It was quite loud at first, not as loud as a Whelen horn but still louder than a regular car horn. A few months after the installation, the temperature where I lived became very low and I noticed that the noise level started to decrease. After all, at very low temperatures, there was almost no noise from itself. I contacted the company that sells this horn and was very surprised when the person I spoke to sent me a brand new speaker and amp to try out. I installed a new speaker and it worked fine and sent back the old speaker and amp which I don't need. As temperatures continue to drop into the single digits where I live, I've noticed this horn getting a little quieter, but still loud enough to be an effective horn. It seems that when the temperature rises above freezing, it returns to normal. I can take a used Whelen speaker and see if there is a difference in sound quality/volume. But overall I'm happy with it. I only gave it 4 stars because of the temperature issue, but it's still a good product and the customer service was way better than I expected.
