2008 AM General HMMWV Humvee owner Greg B. upgraded his military-spec build with our HornBlasters Outlaw Train Horn paired with the HornAir 232 Air Source System (24V) for an aggressive, high-output air horn setup built to match the Humvee’s presence. Outlaw horns deliver tri-tone train horn character with a pre-installed 12/24-volt electric valve—exactly the kind of hardware that pairs cleanly with HornBlasters’ dedicated 24-volt onboard air.
The Outlaw Train Horns and HornAir 232 Air Source System (24V) were installed in the rear cargo/underbody area of Greg’s 2008 AM General HMMWV Humvee, utilizing available frame space for a secure and well-protected mounting location. This setup gives his Humvee a serious increase in sound output while maintaining a clean and functional install suited for heavy-duty use.
The Outlaw horns paired with the HornAir 232 system deliver reliable onboard air performance and a loud, attention-grabbing horn blast, making it a strong match for the rugged platform of the HMMWV. HornBlasters documents the Outlaw Train Horn as part AH-C3B (stealth black) with a deep, full-bodied chord, while the HornAir 232 24V supplies 150 PSI air from a 2-gallon six-port tank with a 24-volt AC-2 compressor— this system requires a 24-volt electrical system and is not for 12-volt trucks without proper conversion.
