The Hertz HCP 5D is a complete five-channel Class D car audio amplifier designed to power front, rear, and subwoofer speakers in a single compact unit. It supports configurations for a full five-channel system or a three-channel setup using the front channels for full range and the dedicated sub channel.

The amplifier is assembled with high-quality components and features a complete and bypassable crossover system with front and rear filters that include a bass boost circuit and a subsonic filter. Cooling is optimized by transferring heat to the heat sink and dissipating it through the amplifier sides. The unit is compatible with the Hertz HRC remote control for precise subwoofer level adjustment and accepts a wide range of inputs for flexible system integration.
