Hertz Dieci Series DP 1.500 Mono Class-D Car Amplifier 300W RMS | 590W Max
Hertz DP 1.500 Mono Class-D Car Amplifier Max 590W
If you want serious bass without giving up boot space, the Hertz DP 1.500 is built exactly for that. This compact Mono Class-D amplifier punches well above its size, delivering up to 590W of maximum power with rock-solid 2Ω stability. Whether you're running a single subwoofer or building a dedicated bass stage, the DP 1.500 gives you the control and headroom to do it right.
What is the Hertz DP 1.500?
The Hertz DP 1.500 is a single-channel (Mono) Class-D car audio amplifier from the Hertz DIECI POWER series. It is engineered for subwoofer duty, offering high output power in a small footprint.

Advanced Technologies
ADC – Advanced Class-D Technology: Traditional amplifiers waste a lot of energy as heat. Hertz's ADC technology takes Class-D efficiency to the next level, achieving 86% efficiency. This means the DP 1.500 runs cooler, draws less current from your car's electrical system, and still delivers powerful, clean bass output. It's the reason this amplifier can be so compact yet so capable.
Universal Speaker Simulator: Most aftermarket amplifiers struggle when connected directly to OEM (factory) head units because of impedance mismatches. The DP 1.500's integrated Universal Speaker Simulator solves this completely, allowing it to accept speaker-level inputs from 1.6 to 40 Vrms — covering virtually every factory radio on the market. No line output converter needed in most cases.
ART – Automatic Remote Turn-On/Off: Wiring a remote turn-on wire from an OEM radio can be tricky. ART detects the speaker signal from your factory radio and automatically powers the amplifier on and off — no extra wiring, no relay, no hassle. It activates at just 1.5 VDC from the speaker output, making it compatible with almost all OEM systems.
Balanced Input Circuitry: Both the Pre-In and Speaker-In inputs use balanced circuitry, which actively rejects electrical noise and interference from your car's wiring. The result is a dramatically quieter background — no alternator whine, no engine noise — just clean, accurate bass.
Benefits
- 🔊 Deep, powerful bass — 590W maximum power drives even demanding subwoofers with ease
- 🚗 Fits anywhere — compact chassis installs under seats, in door panels, or in tight boot spaces
- 🔌 Plug-and-play with OEM radios — no extra converters needed in most setups
- ❄️ Runs cool — 86% efficiency means less heat and longer component life
- 🎛️ Full onboard control — adjust input level, crossover, subsonic filter, and bass boost without a laptop
- 🔇 Dead-silent background — balanced inputs eliminate noise and interference
- 🛡️ Protects your subwoofer — subsonic filter blocks damaging ultra-low frequencies
- 📻 Optional remote bass knob — HRC 02 compatible for easy level adjustment from the driver's seat
Who Should Buy the Hertz DP 1.500?
- Car audio enthusiasts who want serious bass without sacrificing boot space
- Anyone upgrading from a factory head unit and wanting to add a powered subwoofer
- Installers looking for a reliable, OEM-compatible mono amplifier for client builds
- Audiophiles who demand low distortion and a high signal-to-noise ratio in their bass stage
- Drivers who want a set-and-forget amplifier with automatic turn-on from their OEM radio

Q: Does the Hertz DP 1.500 have a built-in crossover?
A: Yes. It includes an adjustable low-pass crossover filter (50–250 Hz @ 24 dB/Oct.) and a subsonic filter (25 Hz @ 24 dB/Oct.) to protect your subwoofer from damaging ultra-low frequencies.
Q: Can I control the bass level from the driver's seat?
A: Yes, the DP 1.500 is compatible with the optional Hertz HRC 02 Remote Control, which lets you adjust the subwoofer level from a convenient dash-mounted knob without reaching into the boot.
Q: What fuse rating does the Hertz DP 1.500 require?
A: It requires a single 30A fuse at the nominal operating voltage of 11–15 VDC. Always install the fuse as close to the battery as possible.
Q: Does the DP 1.500 produce a lot of heat?
A: No. Thanks to ADC (Advanced Class-D) technology with 86% efficiency, the DP 1.500 generates significantly less heat than traditional AB-class amplifiers. It is designed to run cool even during extended listening sessions.
Q: What is the signal-to-noise ratio of the Hertz DP 1.500?
A: The S/N ratio is 99 dBA (A-weighted at 1V input), which is excellent for a car amplifier and ensures a very quiet background with minimal audible noise.
Q: Is the Hertz DP 1.500 available with Pan-India delivery?
