Sundown Audio SALT-2 Class D Amplifier
Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 in the contiguous US. Approved returns may be subject to a restocking fee.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

This Listing Includes: (1) Sundown Audio SALT-2 Class D Amplifier
The SALT-2 is a strappable digital Class-D mono block that delivers 500 watts at 4 ohms, 1,000 watts at 2 ohms, or 2,000 watts at 1 ohm on its own, and a massive 4,000 watts at 2 ohms when linked to a second SALT-2, across a 10Hz–250Hz response. SALT — Sundown Audio Low-Voltage Technology — produces optimum power at realistic voltages in the 12s rather than needing 14+ volts. A 24dB variable subsonic filter (10Hz–50Hz), 24dB variable low-pass filter (35Hz–250Hz), variable bass boost at 45Hz (0–9dB), and 0–180 degree phase shift control dial in the bass, while onboard power, clipping, and protection indicators and full protection circuitry keep it safe. An included wired remote displays voltage, temperature, and clipping. Authorized Sundown Audio dealer at JS Ultimate Sounds. Free shipping on orders $99+.
