HERTZ DP 1.500

The Hertz DIECI POWER DP 1,500 is a high-performance mono amplifier designed specifically for driving subwoofers. Thanks to modern Advanced Class-D technology, it delivers high output power in a compact design with high efficiency. This makes the amplifier ideal for vehicles with limited installation space, without compromising on sound quality or dynamics.

The built-in high- and low-level inputs allow for easy connection to aftermarket and factory-installed radios. The built-in Universal Speaker Simulator (USS) also ensures error-free connection to modern OEM audio systems with speaker recognition. Extensive adjustment options, such as a low-pass filter, subsonic filter, phase switch, and bass boost, allow for precise tuning of the subwoofer to the specific vehicle and audio system. Optionally, the bass level can be conveniently controlled from the driver’s seat using the HRC 02 remote control.
