Hertz HDP 4 amplifier new in box with a small aesthetic defect related to painting in the fixing slots (see real photos of the product on offer). Perfectly functional. Official 24-month warranty.

HDP 4 is a Class D amplifier with four channels suitable for any need.

It is the most compact HDP model but, like the others, it can reach very high power levels: less than 30 cm in length can deliver up to 1000W on 2 channels at 4 Ohm! It can be used either full range or with the crossover adjustable as Lo-Pass/Hi-Pass.


Designed to offer the user maximum operational flexibility, both from the point of view of Speaker In and RCA inputs, and from that of controls with a status monitor that communicates with the user through an LED system. On the Speaker In inputs, the ART™ function is available, Automatic Remote Turn On-Off, which can be disabled by the user.

HDP 4 is ideal for those looking for performance and non-intrusive dimensions.
The heatsink with double extrusion and Hertz logo, backlit and rotatable, allows for particularly refined installations.

  • Heatsink made with double extrusion thermally optimized, ergonomic terminals in die-cast aluminum
  • 4 LEDs monitor the amplifier status with pre-alarm function (flashing)
  • Special balanced input circuitry for high electromagnetic interference rejection, in the Pre-In and Speaker-In inputs
  • HDP Input has Speaker In inputs (for factory car stereos) and RCA In inputs (for aftermarket car stereos)
  • ART, Automatic Remote Turn-On/Off, automatically turns the amplifier on and off when the factory car stereo turns on and off (can be enabled/disabled only with Speaker In)
  • Full range pre-out outputs, also available with Speaker In level inputs
  • Active crossover with 12 dB/Oct. slope continuously adjustable from 50 to 5k Hz and from 80 to 3.3k Hz, adjustable as Lo-Pass/Hi-Pass or Full Range
  • Special A/B input switch that eliminates the need for Y adapters for RCA
  • Power supply with multi-strand winding transformer, LOW-ESR 105°C capacitors, D-Class output stage, stable at 2 Ω (1000W RMS), based on robust T220-5pin power Mosfets.
