Hifonics BG-4000.1D BRUTUS GAMMA 4000 Watt Monoblock Amplifier
Description
Description
The Hifonics BG-4000.1D BRUTUS GAMMA delivers up to 4000 watts of high-efficiency output in a mono configuration, engineered specifically to drive demanding subwoofer setups. Powered by proprietary Super D-Class topology and Ultra-Fi MOSFET output devices, it optimizes power conversion to produce clean, musical bass while keeping distortion minimal and heat generation low.
Featuring a dual-coil Simpatico PWM power supply and a classic aluminum heatsink, this amplifier maintains consistent operating voltage and reliable thermal management during extended play sessions. Secure molded terminals angled for clean cable management, nickel-plated RCA connections, and comprehensive diagnostic LED protection circuitry ensure stable signal integrity and system safety.
Extensive on-board sound shaping includes variable electronic crossovers, a 15Hz to 35Hz subsonic filter, adjustable bass boost, 0 to 180 degree phase shift, and power strapping capability to sync dual units. An included wired remote control allows for seamless real-time bass adjustments directly from the front of the vehicle cabin.
