Product Description
SALT stands for Sundown Audio Low-Voltage Technology. Instead of quoting output at voltages most vehicles never see, Sundown tests at 12.8V with less than 1 percent THD. Operating range is 9V to 15.5V and efficiency is above 90 percent, so current draw stays reasonable for the output. Plan on a 400A fuse and wiring to match.
Filters are steeper than the usual 12dB designs: a 24dB variable subsonic filter from 10 Hz to 50 Hz and a 24dB variable low pass filter from 35 Hz to 250 Hz. Variable bass boost at 45 Hz adds up to 9 dB and phase shift control spans 0 to 180 degrees. Frequency response runs 10 Hz to 250 Hz, signal to noise ratio is above 90 dB, and damping factor is above 400 for tight cone control.
Protection circuitry covers thermal, voltage, speaker short, and DC-offset faults, with power, clipping, and protection indicators. The included wired remote displays voltage, temperature, and clipping, which is exactly what you want to watch on a system at this power level.
Dimensions are 22.05 by 8.67 by 2.80 inches, so plan the rack space before you order.
Features
-
Full Power At Real Voltage
Ratings tested at 12.8V with under 1 percent THD mean the SALT-4 delivers on a normal electrical system instead of demanding 14V or more.
-
Scale To Eight Thousand Watts
Link a second SALT-4 and the pair produces 8000W at 2 ohms, so the amplifier you buy now stays in the system as it grows.
-
Competition-Style Filtering
The 24dB subsonic and low pass filters cut twice as steeply as 12dB designs, keeping output inside the range your enclosure handles best.
-
Tight Cone Control
A damping factor above 400 and efficiency above 90 percent keep woofer motion in check while limiting the current your electrical system must supply.
-
Monitor While You Listen
The included wired remote shows voltage, temperature, and clipping in real time, which matters most on a system running this much power.
