Hertz HCP 4MDK 150W x 4 RMS 4-Channel 2Ω D-Class Marine Amplifier

Design Ready to Face the Open Water Environment, Providing Tons of Clean Power!

4-Channel D-Class Marine Amplifier
The Hertz HCP 4MDK features the latest generation D-Class 2Ω stable output stage reaching the impressive power RMS of 150W x 4 with the excellent S/N ratio of 105dB. Extremely versatile, complete in its functions, provided with Speaker-In and RCA-In inputs to work with any head units, it has been designed to work also in mono (Selectable Mode), providing the ability to build a two zone stereo or a single zone stereo system with subwoofer.

The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier. The HCP 4MDK four channels marine amplifier feature a compact design ready to face the open water environment, providing tons of clean power.

The HCP M amplifiers crossover section ensure extreme flexibility: fully adjustable Lo-pass, Hi-pass filters with 12 dB/Oct. slopes and Bass Boost to enhance low frequencies.
