HERTZ DP 4.300

The Hertz DP 4.300 is a compact 4-channel amplifier designed for high-end car audio systems. Thanks to its Class AB technology, it combines a warm, detailed sound with precise control over the speakers. With its bridgeable channel architecture, the amplifier is suitable for both front and rear systems as well as for high-performance 2-channel or 3-channel configurations with a subwoofer. Its compact dimensions make installation easy, even in vehicles with limited space.

For maximum flexibility, the DP 4.300 features RCA and high-level inputs, allowing it to be easily combined with factory radios or aftermarket systems. Adjustable high-pass and low-pass filters, along with a bass boost, allow for precise tuning of the sound to match the specific vehicle and speaker system. High-quality connection terminals, a protected control panel, and Hi-Res Audio certification underscore this amplifier’s commitment to high quality.
