About the Hertz HCP 1D
Hertz' HCP 1D mono 1-channel amplifier will deliver up to 550 watts RMS to your subwoofer, improving the sound of your bass as well as your listening experience. The amp's onboard variable low-pass and subsonic filters plus a variable bass boost all help your sub sound its best. You can also adjust the phase of the bass signal to optimize the sound for your listening position. An optional HRC wired remote control lets you control the bass level from the front seat. You can also use this full-range Class-D amplifier to power a center-channel or high-performance speaker with 300 watts RMS.
Works in almost any system
This amp will work with an aftermarket receiver using RCA connections, or a factory radio using speaker-level wiring and Hertz' ART™ automatic remote turn-on system. The HCP 1D features preamp outputs, controlled by a variable high-pass filter, which can be used to send signals to an additional amplifier in a larger, multi-amp system.
When you think of Italian cars, you think of style, performance, and awesome sound. Same goes for Italian audio gear. Hertz speakers, subs, and amps have made cars sound super since 1998.

Overview: The Hertz HCP 1D is a mono D-class car amplifier that can drive subwoofers or a full-range speaker. It is part of the Hertz Compact Power (HCP) series, that features a compact chassis and minimized extruded aluminum heat sinks. Heat is transferred away from the internal components and out to the heat sinks where it is dissipated through the sides of the amp. The HCP 1D has both speaker-level and line-level inputs to accommodate factory and aftermarket head units.
CEA-2006 Power Output: The HCP 1D is compliant with the CEA-2006 Amplifier Power Standard, which makes it easy for consumers to compare amplifier power specs from one brand to another. The amplifier's CEA-2006 ratings include:
- RMS Power (4Ω, ≤ 1% THD+N, 14.4 volts): 300 watts x 1
- S/N Ratio (ref. 1W output): 80 dBA
Hertz Power Output Specs: Hertz publishes the following power output specs:
- RMS Output Power (14.4 volts, THD 1%): 320 watts x 1 at 4Ω, 550 watts x 1 at 2Ω
- RMS Output Power (14.4 volts, THD 10%): 380 watts x 1 at 4Ω, 700 watts x 1 at 2Ω
Auto Remote Turn-On (ART): The HCP 1D features ART (Auto Remote Turn-On) which automatically powers on and off the amplifier when an audio signal (or lack of one) is detected on the speaker-level inputs. This is especially helpful when connecting the amplifier to an OEM radio. It eliminates the need for running a remote lead from the head unit to the amp. ART is only available with Speaker Level inputs.
Optional Hertz Remote Control (HRC): The HCP 1D is compatible with the optional HRC remote control. The HRC allows you to adjust the volume down to -50dB or up to 6dB. The rotary control has a detent at 0dB to mark the normal amp output. The HRC comes with a 19.5' cable.
Amplifier Controls: The versatile Hertz HCP 1D has a full array of filters and controls to help you configure your audio system for maximum performance. The controls are located on one end of the amplifier, and include the following:
- Level: The rotary Level control lets you match the input of the amplifier to the output of your head unit. The amp will accept either line level (RCA) or speaker level (harness) inputs. The sensitivity range is 0.2V to 5V (preamp level) or 0.8V to 20V (speaker level).
- Low Pass: You can filter the speaker outputs to connected subwoofers. This rotary low pass filter is continuously variable from 50 to 250 Hz with a slope of 24dB/octave.
- High Pass (Pre-Outs): The amplifier's stereo Preamp Outputs can be filtered to the connected amplifier, even if you are using speaker-level inputs. This rotary high pass filter is continuously variable from 50 to 250 Hz with a slope of 12dB/octave.
- Phase: Phase control lets you optimize the alignment of your subwoofer's bass frequencies with the rest of the system. Properly adjusting the phase maximizes the subwoofer's "attack." The rotary control is continuously adjustable from 0° to 180°.
- Bass Boost: The HCP 1D offers a variable bass boost to increase the output of the subwoofer. This rotary control lets you increase the output of the amplifier from 0 to 12dB at 50Hz.
- Filter: You can choose whether you want to engage the amplifier's low pass filter. When the Filter button in pressed in, the filter is On and the speaker outputs are filtered at the frequency selected on the Low Pass rotary control. When the Filter button is out, the amplifier output is full range, for dual-mono audio systems.
- Subsonic: The Subsonic Filter can be turned on or off with this push-button switch. When pressed in, the Subsonic Filter removes very low, subsonic frequencies (25 Hz and lower) from the speaker outputs to prevent damage to your subwoofers. The Subsonic filter has a 24dB/octave slope.
- Auto Turn-On: You can activate or deactivate the ART (Automatic Remote Turn-On) feature with the 2-way push button.
Connections: The HCP 1D has the following connections:
- Power/Ground/Remote Turn-on: The amplifier is equipped with set-screw type terminals for power, ground, and remote turn-on. The power and ground terminals will accept up to 4 AWG wire, while the remote terminal will accept up to 10 AWG wire. In most cases, 8 AWG power and ground wires are recommended. Typically, an 18 AWG remote turn-on lead is used, unless the Automatic Remote Turn-on (ART) is used. The set screws can be tightened/loosened with the supplied 4mm or 2mm Allen wrenches.
- Fuses: Two 25A ATO (blade type) fuses are installed in the amplifier. Two spare fuses are also included. A 50A fuse should be placed within 18" of the battery on the +12V power wire as well.
- Speaker Outputs: The amp provides speaker outputs for up to two speakers. Both outputs are mono, and are wired internally in parallel. The minimum impedance of the connected load is 2Ω. The set screws can be tightened/loosened with the supplied 2mm Allen wrench.
- RCA Input: Stereo RCA inputs are provided for connecting an aftermarket head unit to the amplifier. The inputs will accept a signal between 0.2V and 5V.
- RCA Output: Stereo RCA outputs allow you to pass on the signal to another amplifier. The preamp output signal can match the input signal, or filtered with a high pass filter (50-250Hz, 12dB/oct).
- Speaker Input: The speaker input, labeled Hi In, has a 4-pin female Molex connector. The source unit's speaker wires (left and right) should be spliced to the Speaker Input harness. The included harness is 7" in length and has a male 4-pin Molex plug. The speaker input will accept a signal between 0.8V and 20V.
- Remote Control: The optional HRC (Hertz Remote Control) allows you to adjust the output volume of the amplifier from the dashboard. The amplifier has a removable 2-pin Euroblock connector. The 2 wires at the end of the HRC cable connect to the screw terminals on the Euroblock connector. A small flat-head screwdriver is needed to tighten/loosen the screws on the connector.
