Our most powerful amplifier ever employs our advanced Single-Cycle Control switching design and R.I.P.S. technology to deliver 1200 W of clean power into any impedance between 1.5 and 4 Ω, giving you the highest degree of flexibility in designing your subwoofer system.

Tight power supply regulation keeps distortion down and maximizes your bass quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price. While targeted primarily to subwoofer applications, the HD1200/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems.

This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

General Features:

  • JL Audio HD Series Monoblock Class D Amplifier
  • *RMS Power Rating (11V-14.5V):
  • 4 ohms: 1200 watts x 1 chan.
  • 3 ohms: 1200 watts x 1 chan.
  • 2 ohms: 1200 watts x 1 chan.
  • 1.5 ohms: 1200 watts x 1 chan.
  • Black powder-coated, gasketed cover
  • RealSink™: Vertical, cast alloy fins effectively dissipate heat
  • Advanced Thermal Rollback protection system
  • Single Cycle Control - high-fidelity, full-range class D
  • Compares the real PWM waveform and then corrects it in each and every cycle
  • (over 400,000 times per second)
  • 80% efficiency at 1/2 rated power for the whole amplifier, including its power supply
  • 60% less current draw than a typical Class A/B car amplifier of equal power
  • Less generated heat, smaller chassis than a similarly powerful Class A/B design.
  • Class D, switching type with patented Single-Cycle Control™ technology
  • Pulse width modulation-regulated switching power supply
  • LED power (green), protect (red) and low impedance (amber) indicators

  • Selectable output polarity, "Phase": 0/180°
  • Selectable State-variable slope: 12 dB/octave Butterworth or 24 dB/octave Linkwitz-Riley
  • Selectable infrasonic filter, "Subsonic": Defeatable or 30 Hz
  • Selectable filter modes: Low-Pass or High-Pass, Defeatable
  • Cutoff Freq. Range: Continuously variable: 50 - 500 Hz
  • Total Harmonic Distortion: <0.03% @ 4Ω (Average at 1kHz)
  • Signal to Noise Ration:
  • Referred to Rated Power: 111 dBA
  • Referred to 1 Watt: 82.2 dBA
  • Frequency response: 6 - 8,000 Hz (+0, -1 dB)
  • Damping Factor: >500 @ 4Ω/50 Hz, >250 @ 2Ω/50 Hz
  • Recommended fuse rating: 100A x 1 (inline, not included)
  • Dimensions: 10.74"L x 7.85"W x 1.93"H

  • 1 Pair of Buffered preamp RCA outputs for daisy chaining the audio signal
  • Speaker level inputs via RCA (JL Audio XD-CLRAIC2-SW required and sold separately
  • Remote bass level input (JL Audio HD-RLC required and sold separately)
  • Optional stacking equipment for HD amplifiers: JL Audio HD Stack Kit

Product Highlights:

  • mono subwoofer amplifer
  • 1,200 watts RMS x 1 (rated power from 1.5 to 4 ohms)
  • variable high- and low-pass filter (50-500 Hz 12 or 24dB/octave)
  • switchable subsonic filter (30 Hz) and output polarity control
  • removable power and speaker plugs
  • optional wired remote for level control
  • Single Cycle Control Class D amplifier design
  • Regulated, Intelligent Power Supply System (RIPS) ensures consistent power output over a wide range of battery voltages and load impedances
  • differential-balanced inputs eliminate noise from your vehicle's electrical system
  • speaker- and preamp-level inputs (speaker-level input requires an optional adapter)
  • preamp outputs
  • 4-gauge power and ground leads and a 100-amp fuse recommended — wiring and hardware not included with amplifier
  • no onboard fuses — when installing multiple amps in a system, an additional 100-amp in-line fuse between the distribution block and the amplifier is recommended
