Upgrade your car audio system with the Hifonics Brutus BG 3000 Watt 1 Channel Amplifier, engineered for powerful performance, efficiency, and advanced control. Designed for universal vehicle fitment, this amplifier delivers dynamic sound across multiple channels, making it ideal for powering speakers and subwoofers with clarity and precision.Built with a Class-D chipset, the Brutus BG amplifier offers high efficiency and a wide frequency range while minimizing energy loss. Its dual toroidal transformer PWM power supply provides increased power capacity and consistent output, ensuring your system performs at its best even under demanding conditions. High-tolerance MOSFET output devices enhance power delivery while supporting fast thermal dissipation for reliable operation.The amplifier features an ultra-low EMI design with shielded inductors, reducing interference and preserving clean, high-quality audio. A mass-loaded extruded aluminum heat sink improves thermal management, keeping temperatures under control and maintaining peak performance over time.Versatility is key with 1-channel operation, allowing both stereo and mono bridged configurations. High and low-level inputs make integration simple with both aftermarket and factory audio systems, while nickel-plated RCA inputs ensure strong, corrosion-resistant connections.A standout feature is the built-in UV meter display, which lets you switch between constant blue illumination, VU meter mode, or off. In VU mode, the logo reacts to your music, helping you fine-tune gain levels visually.Engineered for durability, the amplifier includes triple protection circuits, thermal, overload, and short protection, along with auto turn-on and delayed start features to eliminate unwanted noise and protect your system.
