Hertz DIECI POWER DP 1.500 Mono Class-D compact car audio amplifier is an audio powerhouse designed to elevate your car audio experience to unprecedented heights.

Despite its compact size, the DP 1.500 packs a punch with its maximum power output, featuring ADC (Advanced Class-D) 2Ω stable power output in a small and compact design. This innovative design allows for a potent audio performance without sacrificing space, making it an ideal choice for those seeking uncompromised sound in a limited footprint.

The amplifier's aesthetics are as impressive as its performance. An elegant status LED, solid machined terminal block, and a removable top panel that safeguards controls and connections contribute to a sleek and sophisticated design that seamlessly integrates into any car interior.

Universal compatibility is a key feature of the DP 1.500, offering an operating supply voltage ranging from 9 to 17.5 V and speaker-in input sensitivity from 1.6 to 40 Vrms. The integrated Universal Speaker Simulator enhances versatility, ensuring optimal performance with a wide range of audio sources.

Experience high-noise rejection with the balanced input circuitry of the Pre-in and Speaker-in, allowing for clean and interference-free signal transmission. The full set of controls, including adjustable input levels, low-pass crossover filters (50 ÷ 250 Hz @ 24 dB/Oct.), subsonic filter (25 Hz @ 24 dB/Oct.) and bass boost, provides users with the flexibility to fine-tune the audio to their preferences.

Convenience meets intelligence with the Automatic Remote Turn-On/Off feature, seamlessly triggered by OEM radio speaker outputs. This ensures hassle-free operation and an efficient power management system.

The optional HRC 02 Remote Control Ready provides the ability to tune the subwoofer level for any preference.

Whether utilizing Speaker-In or Pre-In level inputs, the DP 1.500 offers full-range pre-outs, providing further flexibility in system configuration. Elevate your car audio system with the Hertz DIECI POWER Amplifier DP 1.500 – where power, precision, and style converge for an unparalleled listening experience on the road.




ADC (Advanced Class-D) 2Ω stable power output in a small and compact design for maximum power in a compact size.

DIECI POWER amplifiers are ultra-compact to ensure effortless installations in the increasingly narrow spaces of modern vehicles or the factory amp area.

Thanks to the built-in USS technology (Universal Speakers Simulator), DIECI POWER amplifiers can be correctly connected to head units with a “speaker load detection” function that monitors the presence of a low-impedance load to enable the audio outputs.
