Hertz HCP 4 (4-Channel Amplifier)

HCP 4 is a four channels car audio amplifier designed to reproduce any musical genres with four separate channels for multiple configurations. Pre-amplified (Pre-In) inputs and high-level (Speaker-In) inputs allow for connection with any head units. Built to work both in mono, as part of a three-channel system with sub and front, and in stereo for a powerful two-channel system, HCP 4 is a unique model in terms of versatility! 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.

- Lo-Pass: A/B: 50 - 500 Hz @ 12 dB/Oct.

- Band-Pass: -

• Distortion - THD (100 Hz @ 4 Ohm): 0.01%
• S/N Ration (A weighted @ 1V): 103 dB
• Damping Factor (100 Hz @ 4 Ohm): 120

Features

• Compact design built from extruded aluminum heatsink with the top side ensuring effective transfer of the heat.
• 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, AB-Class 2 Ω stable output stage.
• Pre-outs, also available when using Speaker-In level inputs.
• Mono operation mode (selectable) to create 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 (50 Hz to 500 Hz) and Hi-Pass (80 Hz) 12 dB crossover filters. The Hi-Pass fixed frequency filter ensures optimal coupling with sub amplifier, also providing the ability to build a front + rear or a sub + front system.
• Selectable full range power outputs.

Hertz DSK 165.3 (2-way System)

Dieci car audio systems let you realize a high quality audio system with the utmost in simplicity. The woofers employ the exclusive V-cone profile for amazing off-axis response and detailed mid-high range. The TPU (Thermoplastic polyurethane) surround ensures linearity and reduction of unwanted resonance, even at high excursion. High-performance materials, such as the neodymium motor assembly and the PEI membrane, ensure an extended high frequency range. The passive filters are found directly on the supplied connection cables, along with a rich array of accessories increasing the install-friendliness and installation time.
