    Information About This Item

    Marine Audio Has Never Sounded So Good

    High quality audio is no longer just for your car or home, with Hertz a brand well known the world over for producing some of the best audio gear on the market stepping into a new market and developing a range of speakers, subs and amplifiers for marine applications.

    Thanks to the ultra-compact cast-aluminium, IP64 rated chassis, the HMP4D CLass-D 4-Channel amplifier is nature-proof, and the ideal choice for marine,UTV, ATV and motorcycle installations where the unit may be exposed to the elements for periods of time.


    It features an incredible power/size ratio and an easy setup thanks to the integrated crossover filter, with the Front End section featuring a complete and bypassable crossover system providing full system design flexibility with or without external processors - Making for endless connection possibilities with any source. Inputs feature a special balanced circuitry, ensuring high rejection against electro-magnetic interferences, for noise-free results.
