Stetsom Bravo HQ 800.4 - Compact 4-channel amplifier with impressive performance

The Stetsom Bravo HQ 800.4 was developed for car audio enthusiasts looking for maximum power, high sound quality and versatility in a compact format. The modern 4-channel digital amplifier delivers powerful performance for speakers, tweeters, mid-range speakers or smaller subwoofer setups and impresses with its high efficiency and flexible setting options.

With up to 4 x 250 watts RMS into 2 ohms at 14.4 volts, the Bravo HQ 800.4 offers enormous power reserves for demanding sound systems. In bridge mode, up to 2 x 400 watts RMS are available - ideal for powerful front systems or compact bass solutions.

Thanks to the wide frequency range from 5 Hz to 22 kHz, the power amplifier is perfect for full-range applications. The integrated variable high- and low-pass filters enable precise adaptation to almost any loudspeaker system. In addition, the intelligent protection circuits against overheating, short circuits and voltage fluctuations ensure maximum operational safety.

The compact design facilitates installation even where space in the vehicle is limited. Thanks to high-level inputs and automatic switch-on function, the power amplifier can also be easily integrated into modern factory radios.
