GRAVITY

GRAVITY 6000W Class D 1 Ohm Stable Amplifier

SKU CH-92HW-0TFP9

A 6000 W Class D car amplifier stable at 1 Ω with variable crossover, bass boost and subsonic filter

  • TypeAmplifier Installation Kits
  • 6000 W maximum Class D output at 1 ohm for competition-level bass
  • Stable operation at 2 ohm and 4 ohm loads for flexible subwoofer wiring
  • Bass boost adjustable 0–12 dB with low-pass crossover 40–180 Hz and subsonic filter 0–50 Hz
  • High and low level inputs plus variable crossover suit factory or aftermarket head units
  • Compact 431.5 × 211 × 64.5 mm chassis fits tight installation spaces

Competition-Class Power

The Gravity 6000W Class D amplifier delivers 6000W maximum power at 1 Ohm while remaining stable at 2 Ohm and 4 Ohm loads. It targets car audio competitors and bass enthusiasts who need high output for subwoofer systems. A wired bass knob is included for direct level control from the driver position.

Straightforward Integration

High-level and low-level inputs accept signals from factory or aftermarket head units without extra converters. The variable low-pass crossover adjusts from 40 Hz to 180 Hz, the subsonic filter covers 0 Hz to 50 Hz, and bass boost reaches 12 dB. Mounting space must accommodate 431.5 mm length, 211 mm width and 64.5 mm height.

Sustained Output Behaviour

Class D topology maintains efficiency during extended play, keeping thermal rise lower than linear designs. Signal-to-noise ratio exceeds 70 dB and total harmonic distortion stays below 0.2 % across the 8 Hz to 180 Hz band. Builders who need multi-channel amplification or full-range operation should consider other solutions.

Questions about this item

How can I verify the amplifier is delivering clean power after installation?

Measure the signal-to-noise ratio; it should exceed 70 dB, and total harmonic distortion should stay below 0.2 % across the 8 Hz to 180 Hz range.

What accessories come in the package and what must I source separately?

The box includes the amplifier and a wired bass knob; you must supply power and ground cables, speaker wire, RCA or high-level input leads and a suitable fuse.

Which impedance load should I wire my subwoofers to for maximum output?

The amplifier reaches its 6000 W rating at a 1 Ohm load and remains stable at 2 Ohm and 4 Ohm, so choose the lowest impedance your subwoofer configuration allows.
