Hifonics BG-700.1 BRUTUS BG 700 Watt Mono Block Amplifier
Description
Description
The Hifonics BRUTUS BG-700.1 is a high-performance Super D Class mono block amplifier engineered to deliver up to 700 watts of clean, reliable output. Built with dual toroidal transformers and a high-frequency PWM power supply, it maintains optimal electrical efficiency and robust signal stability across demanding audio setups.
Featuring an extruded aluminum mass-loaded heat sink and a four-layer PCB design, this amplifier provides enhanced thermal dissipation while producing ultra-low electromagnetic interference. The front panel features stylized badging with an interactive VU meter mode that illuminates with dynamic blue LED lighting to assist during gain configuration.
Integrated electronics include a variable low-pass electronic crossover, switchable subsonic filter, and onboard bass boost for precise sound shaping. Triple protection circuitry actively guards against thermal overload, short circuits, and abnormal voltage conditions to ensure lasting system durability.

Highlights
| Feature | Description |
|---|---|
| Compatible Vehicle Fitment | Universal |
| Ultra-Low EMI Design | Shielded inductors are used in the BG series for increased sound quality that produces ultra-low EMI. |
| Mass-Loaded Heat Sink | The mass-loaded extruded aluminum heat sink results in better thermal management and output performance. |
| High-End Preamplifier Circuit | Accepts a wider range of input signals. |
| RCA Inputs | Nickel-plated RCA jacks create an efficient connection that are corrosion-resistant. |
| High Tolerance Output Device | BRUTUS BG amplifiers have MOSFETS designed for high output power and fast thermal dissipation through a SMT process that produces ultra-low EMI. |
| Operation Mode | Mono only |
| Clean Board Construction | 4-layer PCB design, using a thinner substrate, improves heat dissipation and enhances performance stability. |
| Class / Topology | BG amplifiers feature a Class-D chipset, making them more efficient and allowing for a wide frequency range. |
| Power Supply | Dual toroidal transformers paired with a high-frequency PWM drive results in higher power capacity compared to other transformer designs. This system is protected by a current overload limiter. |
| Delayed Turn-On Function | Ensures compatibility with a wide range of source units to eliminate unwanted turn-on/off noises like hisses and pops. |
| Connection Type | Secure molded connection terminal for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire management profile. |
| Stylized Badging | Switch between full constant blue LED lights, VU Meter mode, or full off. When switched to VU Meter mode, the amplifier’s logo reflects the audio level, useful for gain adjustment. |
| Triple Protection Circuits | Over/under voltage, short circuit, and thermal protection circuits protect the audio system and vehicle under nearly every circumstance. |
| Bass Remote Included | The mono amplifier includes a bass remote that allows adjustment of the gain level relative to the setting on the amplifier’s end panel. |
