About: Hertz HMP4D Compact 4-Channel Amplifier — 50W RMS x 4 (Final Sale Item)

The unit has been used before. It has been thoroughly inspected and tested to ensure it meets the same performance standards. It includes the original manufacturer packaging.

Thanks to the ultra-compact cast-aluminium chassis (IP64 rated), the HMP 4D amplifier 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.
