HCP 1DK is a mono car audio amplifier with an incredibly minimized size heat sink. 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.
HCP 1DK has been designed to work in multiple configurations. More specifically, it features Hi-Pass pre-amplified outputs, providing the ability to create a Band-Pass on the front woofer.
Besides, using the HRC accessory (Hertz Remote Control), the subwoofer volume can be remote controlled with extreme preciseness.

The extruded aluminum heatsink provides high efficiency thermal performance; using the top side of the heatsink to effectively dissipate the heat generated by the electronic components. The internal temperature remains constant at all power levels.
Large array of filters customized for each model, to achieve maximum versatility: Lo-Pass, Hi-Pass, Band-Pass, Full Range, Subsonic, Bass Boost, Phase and Mono. Filtered pre-amplified outputs along with multiple adjustments are featured on the HCP 1D, offering the user endless connection possibilities with any source.
Special balanced input circuitry rejects electro-magnetic disturbances present on the Pre-amplified or Speaker level inputs. Power supply stage features a multiple winding transformer and Low-ESR 105.
Automatic Remote Turn-On/Off function, automatically turns the amplifier on and off with the OEM radio; eliminates the need for a remote signal from the source when using the Speaker-In. This function can also be disabled.
