The Hifonics BG-2500.1D BRUTUS GAMMA is a mono subwoofer car audio amplifier built around Super D-Class technology and Ultra-Fi MOSFET output devices, delivering up to 2500 watts for a single subwoofer channel. Its variable electronic crossover, built-in bass control, subsonic filter and 0-180 degree phase adjustment let you tune low-frequency output to match your subwoofer and enclosure.

Nickel-plated RCA inputs and high-temperature nickel-plated output connectors keep connections secure, while the classic aluminum heat sink and Simpatico Coil power supply manage heat and voltage under high output. A wired bass remote is included so bass frequencies can be adjusted from anywhere in the vehicle, and LED diagnostics monitor overload and speaker short protection.
