It&nbsp;features an incredible power\/size ratio and&nbsp;an easy setup thanks to the integrated crossover filter.&nbsp;The Front End section features a complete and bypassable&nbsp;crossover system, providing full system design&nbsp;flexibility with or without external processors, offering the&nbsp;user endless connection possibilities with any source.&nbsp;Inputs feature a special balanced circuitry, ensuring high&nbsp;rejection against electro-magnetic interferences, for&nbsp;noise-free results.&nbsp;The level of HMP 1 D amplifiers can be remote controlled&nbsp;with the included HRC BM (Hertz Remote Control Bass&nbsp;Management). Connected to the Remote Control plug,&nbsp;this provides extremely precise volume level from the&nbsp;comfort of your seat.<\/p>\r\n\r\n<div class=\"product-layout-informations
