Every aspect of the Warhorse was tortured mercilessly in our labs to ensure extreme performance and reliability. It was engineered completely in-house by KICKER Research and Development for ultra-high SPL applications. From the board layout to the rails, to the Tiffany-style RCA connectors, everything about these amps will make a bass head smile from ear to ear. The Warhorse was bred to compete! Engage Competition mode to lock the gain voltage at 4 volts for easy gain-matching across multiple amps, amongst other slick features. Warhorse Amps come with a heavy-duty, magnetic-mount diagnostic tool, displaying battery voltage, amp temp, power-supply protection, and speaker current overload, all in real time!
