Our take on the Hifonics Brutus BG Class D Monoblock Amplifier with Built-In UV Meter, 700 Watt

The Hifonics Brutus BG is a single-channel Class D amplifier rated at 700 watts, built to drive a subwoofer in a car audio system. Its standout feature is a built-in UV meter that can glow blue, react to the music in VU mode, or switch off, giving a visual read on gain. High- and low-level inputs, stereo and bridged modes, and triple thermal, overload and short-circuit protection make it flexible for factory or aftermarket head units. It is a value-focused alternative to premium monoblocks, with a mass-loaded aluminum heat sink and shielded, low-EMI construction; owners of budget Class D amps often note these run cool but can be sensitive to clean power and grounding.

About the Hifonics Brutus BG Class D Monoblock Amplifier with Built-In UV Meter, 700 Watt

The Hifonics Brutus BG is a Class D monoblock car amplifier that delivers 700 watts. It uses a one-channel design for a dedicated subwoofer or speaker setup. It accepts high- and low-level inputs, so it connects to factory or aftermarket audio sources. Stereo and bridged modes are available.

A built-in UV meter can be set to blue illumination, VU meter operation, or off. In VU mode, the logo responds to the music and gives a visual reference for adjusting gain.

Dual toroidal PWM power supplies and high-tolerance MOSFET output devices handle power delivery. Shielded inductors and ultra-low EMI construction limit unwanted signal disruption. A mass-loaded extruded aluminum heat sink manages operating temperature. Triple protection circuits cover thermal, overload and short-circuit conditions. Auto turn-on and delayed start functions help manage startup.

Questions and answers

What subwoofer can this 700-watt monoblock drive?
It is a single-channel Class D amp rated at 700 watts, suited to one subwoofer or a small sub pair within that power range. Match the sub's RMS rating to the amp's output and set gain with the VU meter as a guide.
Does the UV meter affect sound?
No. It is a visual display that can glow blue, move with the music in VU mode, or be turned off. In VU mode the logo reacts to the signal and helps you set gain by eye.
Can I connect it to a factory radio?
Yes. It has high-level inputs for factory head units and low-level nickel-plated RCA inputs for aftermarket sources. Auto turn-on and delayed start help with startup behavior.
Does it power door speakers too?
No. It is a one-channel monoblock, so it drives a subwoofer or a bridged speaker setup. Door and component speakers need a separate multi-channel amplifier.
How is it protected from overheating?
Triple protection circuits cover thermal, overload and short-circuit conditions, and the mass-loaded extruded aluminum heat sink manages operating temperature. Mount it with airflow around the fins.
What is in the box?
The amplifier itself, finished in silver and measuring 12.7 x 8.2 x 3.66 inches at 5.1 lb. Wiring and installation hardware are not part of the unit, so plan for an amp kit separately.
