HCP 4 is an amplifier designed to reproduce any musical genres with four separate channels for multiple configurations. Pre-amplified (Pre-In) inputs and high-level (Speaker-In) inputs allow for connection with any head units. Built to work both in mono, as part of a three-channel system with sub and front, and in stereo for a powerful two-channel system, HCP 4 is a unique model in terms of versatility!
All the Hertz Compact Power amplifiers are assembled with high-quality components and feature a complete and by-passable crossover system. The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier.

- 1. Compact design built from an extruded aluminum heatsink with the top side ensuring effective transfer of the heat generated by the power electronic components.
- 2. Special balanced input circuitry to reject electromagnetic disturbances present on the Pre-amplified or Speaker level inputs.
- 3. Input featuring both Speaker-In (OEM radio) and RCA-In (Aftermarket radio) inputs.
- 4. Selectable ART™, Automatic Remote Turn-On/Off function, automatically turns on and off the amplifier when the OEM radio turns on and off (available on Speaker-In only).
- 5. Power supply stage featuring multiple winding transformer, Low-ESR 105°C capacitors, AB-Class 2 Ω stable.
- 6. Pre-out, also available when using Speaker level inputs.
- 7. Mono operation mode (selectable) to realize a sub + front three-channel system, or a powerful two-channel system.
- 8. Bass Boost (50 Hz) selectable to 12 dB, to increase the subwoofer punch.
- 9. Lo-Pass (50 Hz to 500 Hz) and Hi-Pass (80 Hz) 12 dB crossover filters. The Hi-Pass fixed frequency filter ensures optimal coupling with sub amplifier, also providing the ability to realize a front + rear or a sub + front system.
- 10. Selectable full range power outputs.
