HCP 4 is a four-channel car audio amplifier designed to reproduce all musical genres with four separate channels for multiple configurations. Pre-amplified inputs (Pre-In) and high-level inputs (Speaker-In) allow connection to a wide range of head units and source units while supporting stereo, mono and three-channel sub/front setups.

Part of the Hertz Compact Power series, the HCP 4 is assembled with high-quality components and includes a complete and bypassable crossover system. The thermal design transfers heat to the heat sink and dissipates it through the amplifier sides to help maintain stable operation during extended use.
