Fernando R. gave his 2016 GMC Sierra HD2500 a serious sound upgrade by installing the HornBlasters Octohorn Train Horn . Mounted under the truck bed , the Octohorn Train Horn keeps the installation clean and out of the way while delivering the unmistakable, attention-grabbing blast HornBlasters is known for.
The under-the-truck-bed mounting location makes excellent use of available space without sacrificing performance, making it a great setup for anyone looking to add a powerful train horn to their GMC HD truck.
Awesome work, Fernando! Thanks for choosing HornBlasters and sharing your build with us.
