DC Audio 9.0k 9000 watt Mono Block Amplifier

The DC Audio 9.0k is a 9000-watt mono-block amplifier built for extreme subwoofer builds and competition-grade installs. It’s 1 ohm stable and designed to pair with a second unit for up to 22,000 watts in a linked setup, with a bass knob included for on-the-fly tuning.

• 1 Ohm stability: Optimized for very low-impedance loads, enabling maximum output from demanding subwoofers without clipping or strain.
• Power output (RMS) at 14.4V: 2,400x1 @ 4 ohms; 4,800x1 @ 2 ohms; 9,000x1 @ 1 ohm; 18,000x1 @ 2 ohms. These figures describe real-world SPL potential per channel at standard automotive voltages.
• Linked power (at higher voltages): When paired, 9,800x1 @ 1 ohm @ 16.0V; 19,600x1 @ 2 ohm @ 16.0V; 11,000x1 @ 1 ohm @ 18.0V; 22,000x1 @ 2 ohm @ 18.0V. Linking increases total output in high-voltage scenarios for peak performance from a pair.
• Bass knob included: Allows immediate bass level adjustment from the listening position, complementing its built-in bass management features.
• Variable low pass filter & Subsonic filter: Precise frequency shaping from 20 Hz up to 250 Hz with a separate subsonic range from 10 Hz–50 Hz to protect woofers and tighten bass.
• Bass boost @45 Hz 0–9 dB: Enhances deep-bass presence without altering higher frequencies, giving you tonal control at the port or characteristic sub frequencies.
• RCA Pass Thru: Passes the input signal through to another amplifier, enabling cascading or multi-amp setups without extra signal processing.
• Linkable & wired remote control: Pair amps for higher output and adjust bass remotely for convenience during tuning sessions.
• 8 AWG terminals + triple 1/0 AWG power/ground inputs: High-current wiring capacity to minimize voltage drop and keep power delivery clean under heavy load.
• Full specs and build: Master/Slave operation, external 300A x 3 fuse arrangement, power/protect LED indicators, and a substantial heatsink (34.64" L × 11.5" W × 2.6" H) for thermal stability.

In a real car audio build, the 9.0k excels as the dedicated sub amp in a high-SPL system, delivering clean, high-current power to a single sub or paired subs when linked. Its comprehensive crossovers, bass shaping, and remote control enable precise tuning, while the robust cooling and multiple high-amp inputs support long, demanding sessions without performance loss.
