SAEv4-600D

The SAEv4-600D is a compact Class D monoblock rated at 600W x 1 at 1 ohm, 450W x 1 at 2 ohms, and 250W x 1 at 4 ohms. It is the right size for a single 8, 10, or 12-inch subwoofer, or a shallow-mount sub in a truck, where a bigger amp would only add current draw you do not need.

The half-bridge Class D design keeps output clean across the impedance range, and the control set covers real tuning work. A 12dB variable low pass filter from 40 Hz to 180 Hz sets the crossover to your midbass, a 12dB subsonic filter from 10 Hz to 40 Hz keeps content below box tuning out of the woofer, and phase shift control across 0 to 180 degrees times the sub to the front stage.

Protection circuitry covers thermal, voltage, speaker short, and DC-offset conditions, with power, clipping, and protection indicators on the chassis. The heavy aluminum heat sink handles thermal control through extended playback in a warm cabin or trunk.

The included wired remote control has a clipping indicator, so sub level is adjustable from the driver seat and you can hear and see where clean output ends.

Operating voltage is 10.5V to 15.5V with a 60A recommended fuse, so many installs work with existing wiring. At 9.8 by 6.3 by 2.75 inches, it fits under a seat, behind a panel, or beside an existing amplifier.
