Hifonics BG-1900.1D BRUTUS GAMMA 1900 Watt Amplifier
Description
Description
The Hifonics BRUTUS GAMMA BG-1900.1D mono subwoofer audio amplifier delivers up to 1900 watts of high-efficiency output utilizing Super D-Class design technology. Equipped with Ultra-Fi MOSFET outputs, this unit balances precise musical production, minimal harmonic distortion, and optimal thermal efficiency.
Built with a classic aluminum heat sink and a Simpatico Coil dual-coil Pulse Width Modulated power supply, the amplifier maintains consistent operating voltage and reliable heat dissipation. Angled, secure molded connection terminals and nickel-plated RCA jacks provide clean, corrosion-resistant terminations for high-quality audio transfer.
On-board sound shaping features include a variable 12dB per octave electronic crossover, an adjustable subsonic filter, bass boost control, and 0 to 180-degree phase shift adjustment. A wired remote is included to allow convenient bass level adjustments from anywhere within the vehicle cabin.
