HCP 5D is a front + rear + sub complete car audio amplifier with five very powerful  D class channels. It features a wide range of inputs to obtain the best configuration with every car audio source. HCP 5 D is suitable in a five channels system with subwoofer, in a three channel front + sub system using the front and rear built-in filters that include also a bass boost circuit and a subsonic filter. 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. Besides, using the HRC accessory (Hertz Remote Control), the subwoofer volume can be remote controlled with extreme preciseness.
