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-1.5 Class D Amplifier
The SALT-1.5 is a linkable digital Class D monoblock that produces 1,500W at 1 ohm, 750W at 2 ohms, and 400W at 4 ohms in mono, or 3,000W at 2 ohms when linked to a second SALT-1.5. Built on Sundown Audio Low-Voltage Technology, it produces optimum power at realistic charging voltages rather than needing 14+ volts. A 24dB variable subsonic filter (10Hz–50Hz), 24dB variable low-pass filter (35Hz–250Hz), variable bass boost at 45Hz, and 0–180 degree phase control let you dial in the exact response you want. The included wired remote displays voltage, temperature, and clipping for real-time monitoring. Authorized Sundown Audio dealer at JS Ultimate Sounds. Free shipping on orders $99+.
