INCREDIBLE PERFORMANCE AND VERSATILITY COMBINED

The SP 4.900 4 / 3 / 2 channel amplifier is designed so that music can be enjoyed in the familiar Hertz sound quality in as many areas of use as possible. The ADC (Advanced D-Class) amplifier performs with an efficiency of up to 85%, which is unique in its category. USS (Universal Speakers Simulators) allows the SP 4.900 amplifier to be connected to OEM head units with a "speaker load sensing" circuit, so it can also be installed in the latest car models.

HUGE POWER PLANT IN A SMALL BOX

Despite its ultra-compact size, its performance is really convincing, capable of delivering 160 W of continuous power per channel at a 4 Ohm load. Thanks to the IP55 aluminum housing of the SP 4.900, it works safely not only in cars, but also in boats, thanks to its maximum protection against moisture and other natural influences. The cooling of the amplifier is passive (no fan), this technology prevents the accumulation of internal dirt and the infiltration of moisture.

EASY TO INSTALL AND SIMPLE TUNE!

The special sealed power cable, line-level input and speaker output provide additional protection against oxidation. The crossovers and controls are placed on one side, making it easy to set up after installation.
