Description
The Sundown Audio SFB-3000D is a high-output mono car audio amplifier made for subwoofer systems that need serious RMS power from one compact Class D chassis. It supports 1-Ohm stable operation and pairs strong output with system tuning controls for daily driver, demo, and custom car audio builds. This amplifier delivers 3000W RMS at 1 Ohm, 2000W RMS at 2 Ohms, and 1100W RMS at 4 Ohms, giving installers flexible wiring options for compatible subwoofer loads. A dual MOS-FET PWM power supply supports consistent output, while the recommended 250A fuse rating matches the amplifier's power demands. Built-in tuning includes a 12 dB per octave variable low pass filter and 0 to 12dB variable bass boost for dialing in low-frequency response. Four-way protection covers thermal, voltage, speaker short, and DC offset conditions, and the smart three-speed temperature-activated fan helps manage heat during heavy playback. Technical Highlights: Power Output: 3000W RMS at 1 Ohm, 2000W RMS at 2 Ohms, 1100W RMS at 4 Ohms Voltage Range: 10.5V to 15.5V DC working voltage Signal Noise Ratio: 86dB rating Size: 9.00 x 8.25 x 2.50 inches The SFB-3000D is suited for car audio hobbyists, installers, and subwoofer owners building a single-amplifier bass system. Its mix of 1-Ohm power, wired remote with clipping indicator, protection circuitry, and compact size gives it a strong fit for high-power subwoofer setups without adding multiple amplifiers.
