Sundown Car Audio 8000W 1 Ohm Class D Monoblock Amplifier w/ Bass Control SALT-8

This Listing Includes:

• (1) Sundown 8000W 1 Ohm Amplifier SALT-8


• (1) Bass Control

The Sundown Audio SALT-8 is built for serious bass enthusiasts who want massive power, clean response, and tight control over their substage. Rated at 8,000 watts RMS x1 @ 1 ohm, this Class-D monoblock amplifier is designed for extreme SPL builds, demo vehicles, and high-output daily systems that demand real power on tap. When linked, the SALT-8 can deliver up to 16,000 watts RMS x1 @ 2 ohms, making it a centerpiece for ultra-high-output setups.

At its core, the SALT-8 uses a digital Class-D design with a dual MOS-FET PWM power supply for efficient, consistent output. The tuning section is loaded with tools to dial in your subs: 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. A phase shift control from 0–180 degrees lets you align your subwoofers with the rest of your system for maximum impact.

To protect your investment, Sundown includes a 4-way protection circuit that continuously monitors thermal conditions, supply voltage, speaker short circuits, and DC offset. The included wired remote does more than just adjust output: it displays system voltage and temperature and features a clipping indicator, giving you live feedback so you can push the system hard without guessing.

Designed to operate from 9–15.5V and tested at 12.8V with less than 1% THD, the SALT-8 is engineered for real-world use in serious builds. With its large footprint and an 800-amp recommended fuse rating, proper electrical upgrades are required, but the payoff is crushing low-frequency performance backed by Sundown Audio’s reputation in the high-power game.
