Description

Sundown Audio SALT-12

SALT‑12 is an ultra‑high‑power, mono‑block Class‑D amplifier from the “SALT” series by Sundown Audio. It’s designed for extreme SPL (sound‑pressure‑level) and subwoofer‑heavy car audio systems. The amp delivers massive power even on standard 12 V vehicle systems  no special high‑voltage supply needed. It includes variable low‑pass and subsonic filters, bass boost, phase shift control, multi‑way protection circuitry (thermal, voltage, speaker‑short, DC offset), and a wired remote control with voltage/temperature/clipping indicators.

About The Product

Sundown’s biggest powerhouse, the SALT-12 delivers a mind-twisting 12k at 1 ohm. The amp features both a 24dB variable subsonic and low pass filter, along with a bass boost at 45Hz, letting you dial in your personal, perfect sound. The phase shift control makes it easy to precisely adjust the output. With onboard indicators for power, clipping, and protection you’ll have full control over your setup. Use the included wired remote control to see voltage, temperature, and clipping at a glance.

Producing optimum power at realistic voltages (the 12s, rather than needing 14+ volts), the SALT – Sundown Audio Low-Voltage Technology – is Sundown’s answer! SALT amplifiers represent the pinnacle of Korean Class-D amplifier technology. Whether you are a world-class SPL competitor or simply want to bang harder than absolutely anyone else, the SALT series will be right at home in your system.
