Description
Description
This Hifonics BRUTUS BG four-channel amplifier delivers 520 watts max power with a dual toroidal transformer PWM power supply and a built-in VU meter that reflects audio levels for easy gain adjustment. It runs 4 x 75 watts at 4 ohms, 4 x 125 watts at 2 ohms, or 2 x 260 watts bridged at 4 ohms, so you can drive a full set of speakers or bridge it for subwoofer duty. High-level inputs and auto turn-on let it tie into factory systems without RCA outputs, while variable crossovers, bass boost, and triple protection circuits keep the setup flexible and safe.
