HERTZ (HMP 1D) 300WX1 RMS D-CLASS MONO MARINE & POWERSPORTS AMPLIFIER 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.
