Just Don't Cut Me Off!

This setup was put on a 2018 Ford Focus ST. The tank and with two compressors were installed inside in the rear. I removed the space saver spare (which is useless anyway and I have Triple "A") to keep the equipment environmentally clean and in reality, was the only place to put them. When both compressors kick in, in my opinion are quiet. The 4 horns were installed nicely in the rear below the spare compartment. With two horns facing port side and two horns facing starboard side, as to not be too loud in the cabin, they produce a commanding sound. I highly recommend "The Conductors Special Nightmare Edition".

Big Boy Horns for my Big Boy Truck!

These horns are great!! Now that I have them installed in my truck, I actually look forward to idiots in traffic. I custom fabricated my own horn rack to go in the box of my truck. They may be out of sight but definitely not out of earshot. I've had them in my truck for just over a week now and look forward to any excuse to use them. Thank you HornBlasters for making an awesome product and for all your help through the ordering process to shipping them to my home in Canada. You guys are great!! Brian H

Fantastic

Fantastic product; it's loud, very loud. It's already kept me from getting hit by distracted drivers. Big enough tank that I've been able to connect tools with no issues. I have also used it to inflate river tubes and other floats. I will be recommending this product and will also be purchasing a motorcycle horn.
