Audio - Car Amplifiers

HCP 5D is a front + rear + sub complete car audio amplifier with five very powerful  D class channels. It features a wide range of inputs to obtain the best configuration with every car audio source. HCP 5 D is suitable in a five channels system with subwoofer, in a three channel front + sub system using the front and rear built-in filters that include also a bass boost circuit and a subsonic filter. 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. Besides, using the HRC accessory (Hertz Remote Control), the subwoofer volume can be remote controlled with extreme preciseness.

Thanks to the ultra-compact cast-aluminium chassis (IP64 rated), the HMP 1D amplifiers is nature-proof, being the ideal choice for UTV/ATV/motorcycle installations. It features an incredible power/size ratio and an easy setup thanks to the integrated crossover filter. The Front End section features a complete and bypassable crossover system, providing full system design flexibility with or without external processors, offering the user endless connection possibilities with any source. Inputs feature a special balanced circuitry, ensuring high rejection against electro-magnetic interferences, for noise-free results. The level of HMP 1 D amplifiers can be remote controlled with the included HRC BM (Hertz Remote Control Bass Management). Connected to the Remote Control plug, this provides extremely precise volume level from the comfort of your seat.

HP 802 is an AB Class stereo spl car audio amplifier, able to deliver up to 1800W. The power supply stage is overbuilt featuring components selected for their robustness, efficiency and reliability even for extended time operation. The output stage features an oversized power supply with 4 toroidal transformers, providing the ability to deliver remarkable power and work stable into 1 Ohm load.
The array of the featured filters is remarkably complex, beyond the standards of mobile electronics in this category: separate Hi-Pass and Lo-Pass filters, able to be configured into a 50 Hz – 10 Hz adjustable Band-Pass filter. A parametric equalizer is also on board, to optimize the response on amplified channels, as well as a Pre Out, to re-launch the input signal to another HP 802 in a multi-amplified system without limits on the number of ways.

SP 4.500 features Hertz ADC (Advanced D-Class) output stage, reaching up to 87% efficiency and delivering an impressive power rating of 90 x 4 (4Ω) W RMS or 300 W x 2 (4Ω) W RMS when bridged, with an ultra-compact size of 192.7 (7.58) x 130 (5.1) mm (in.) x 49 (1.9). Being ultra-compact with impressive power, SP 4.500 is the ideal choice for Motorcycle applications and for under-seat in sports cars and behind-seat installations in trucks.
