I am not usually into loud things but after totaling my car because I was sideswiped by a truck it made me want something louder. My searches led me to Hornblasters and I am so glad! We took the kit to a local installer and they had it installed in 4 hours. The first time I hit the button I jumped even though I was expecting it to be loud. I was not expecting THAT! My husband now insists on one for his pickup so I know another one is in our future!

Loud Loud Loud oh and LOUD

I wanted a cheaper way to get a train horn on my 19 Colorado and saw this kit come up on their site. It was meant to be since it fit perfectly in my toolbox and the horns are all mounted under my bed. This thing will scare the pants off anyone! I love my hornblasters and love sharing them with anyone who gets in my way.

Perfect in my Civic!

I bought this kit to go in my 2021 Honda Civic and couldn't be happier! I bolted the air tank and compressor down in my trunk and put the horns behind my front bumper. To say it's loud is an understatement!! I am so happy with the sound and the service.
