Hertz HCP 1DK


The brand new Hertz HCP 1DK provides almost twice the power of the HCP 1D. Now rated at an impressive 740 Watts RMS into 4 Ohms, this compact monster will happily drive a 2 Ohm load producing a whopping 1240 Watts RMS.

  • Compact design built from extruded aluminum heatsink with the top side effective transfer of the heat generated
  • Special balanced high-noise rejection input circuitry on the Pre-In or Speaker-In inputs.
  • Speaker-In (for OEM head units) and RCA-In (for Aftermarket head units) inputs.
  • Selectable ART, Automatic Remote Turn-On/Off function, automatically turns on and off the amplifier when the OEM radio turns on and off (can be enabled/disabled, with only Speaker-In inputs).
  • Power supply featuring multiple winding transformer, Low-ESR 105°C capacitors,D-Class 2 Ω stable output stage.
  • Pre-outs, also available when using Speaker-In level inputs, equipped with Hi-Pass bfilter with adjustable 12 dB/Oct. slope with continuity between 50 and 250 Hz, providing the ability to create Front + Sub multi-amplification active systems.
  • Adjustable Bass Boost (50 Hz) with continuity between 0 dB and 6 dB, for more punch from the subwoofer.
  • Full-range and Lo-Pass crossover filters with 24 dB/Oct. slope and variable frequency (50 Hz – 250 Hz), both selectable, with a greater application versatility for the design of active systems.
  • SUBSONIC filter (24 dB – 25 Hz), removes very low subsonic frequencies from music signal to prevent damage to the subwoofer. Continuously adjustable PHASE control (0 to 180°); it optimizes alignment of woofer bass frequencies with sub ones.
  • Optional Remote Volume Control (HRC); providing the ability to adjust subwoofer volume level from the dashboard.
