Sundown 6000 Watt RMS 1-Ohm Class D Monoblock Amplifier w/ Bass Control SALT-6

This Listing Includes:

• (1) Sundown 1-ohm Amplifier SALT-6


• (1) Bass Remote

The Sundown Audio SALT-6 is built for serious bass heads who demand huge power and tight control from their amplifier. Rated at 6,000 watts RMS x1 @ 1 ohm, this Class-D monoblock is ready to drive heavy subwoofer setups in demo vehicles, competition builds, and extreme daily systems. For even more output, the SALT-6 is linkable, delivering up to 12,000 watts RMS x1 @ 2 ohms when run in a linked configuration.

At the core of the SALT-6 is a digital Class-D design with a dual MOS-FET PWM power supply, engineered for high efficiency and strong current delivery. A full suite of tuning controls includes a variable subsonic filter from 10–50 Hz, a variable low pass filter from 35–250 Hz (both with steep 24 dB/octave slopes), and a bass boost centered at 45 Hz, adjustable from 0–9 dB. Phase shift control from 0–180 lets you align your substage with the rest of your system for maximum impact.

To help protect your investment, Sundown built in a 4-way protection circuit that monitors thermal conditions, voltage, speaker shorts, and DC offset. The included wired remote doesn’t just adjust level – it also displays system voltage and temperature and features a clipping indicator, giving you real-time feedback from the driver’s seat.

Operating from 9–15.5V and tested at 12.8V with less than 1% THD, the Sundown SALT-6 is made to perform under real-world conditions. With a large footprint and a high recommended fuse rating of 600 amps, proper electrical upgrades are a must, but the reward is a brutally strong, clean, and controlled low-frequency foundation for your build.
