HCP 4D

• HCP 4D is a D Class car audio amplifier, able to offer up to 1160W (RMS); it is the ideal choice for those who want high power levels in complex systems.
• 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), for a three-channel system with sub and front, or a powerful two-channels system.
• All the Hertz Compact Power amplifiers are assembled with high-quality components and feature a complete and by-passable crossover system.
• The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier.
