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.

Q: Is the Hertz DP 1.500 compatible with my factory (OEM) head unit?
A: Yes. The DP 1.500 features an integrated Universal Speaker Simulator and accepts speaker-level inputs from 1.6 to 40 Vrms, covering virtually all OEM factory radios without needing a separate line output converter.
Q: What is ART (Automatic Remote Turn-On/Off) and how does it work?
A: ART detects the audio signal from your OEM radio's speaker output and automatically powers the amplifier on when music plays and off when it stops. It activates at just 1.5 VDC, so no extra remote wire or relay is needed in most OEM installations.
Q: What is the minimum impedance the DP 1.500 can handle?
A: The DP 1.500 is stable down to 2Ω, which covers the most common single subwoofer wiring configurations including dual voice coil (DVC) subwoofers wired in parallel.
Q: What amplifier class is the Hertz DP 1.500?
A: It is a Class-D amplifier using Hertz's ADC (Advanced Class-D) technology, which achieves 86% efficiency — meaning it runs cooler and draws less current than conventional amplifier designs.
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.
