Hertz HCP4D - 4 Channel Class D 1160watt 4-Channel Car Amplifier

The Hertz Compact Power HCP 4D is a D Class amplifier, able to offer up to 1160W (RMS); it is the ideal choice for those who want high power levels in complex systems.

Extremely versatile, complete in its functions, provided with Speaker-In and RCA-In inputs to work with any head units, it has been designed to work also in mono (selectable mode), for a three-channel system with sub and front, or a powerful two-channels system.

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.

Features

• Compact design built from an extruded aluminum heatsink with the top side ensuring effective transfer of the heat generated by the power electronic components.
• Special balanced input circuitry to reject electromagnetic disturbances present on the Pre-amplified or Speaker level inputs.
• Input featuring both Speaker-In (OEM radio) and RCA-In (Aftermarket radio) inputs.
• 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).
• Power supply stage featuring multiple winding transformer, Low-ESR 105°C capacitors, D-Class 2 ? stable.
• Pre-out, also available when using Speaker level inputs.
• Mono operation mode (selectable) to realize a sub + front three-channel system, or a powerful two-channel system.
• Bass Boost (50 Hz) selectable to 12 dB, to increase the subwoofer punch.
• Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 3200 Hz) filters, providing the ability to realize a front + rear system, a multichannel woofer + tweeter system or a powerful sub + front system.
• Selectable full range power outputs.
