ZD-1350.4D 1350W 4-Channel Class D Amplifier

The Hifonics Zeus Delta ZD-1350.4D is a four-channel Class D amplifier built around a PWM MOSFET power supply, designed to power a full set of speakers or bridge down to run a pair of subwoofers when the install calls for it. It pushes 1350 watts total, breaking down to 335 watts per channel at 2 ohms or 170 watts at 4 ohms, and bridges to two channels at 675 watts each in mono mode. An onboard electronic crossover with both high pass and low pass filters adjustable from 50Hz to 250Hz lets you split frequencies between speakers and a subwoofer, or run all four channels full range for a straightforward speaker upgrade. Nickel-plated RCA inputs resist corrosion, and a DC signal sense feature turns the amp on automatically from the incoming RCA signal, removing the need for a separate remote turn-on wire in installs where running one is inconvenient. An aluminum heat sink handles heat generated during extended playback, and secure molded connection terminals keep power, ground, and speaker wiring organized. Because the amplifier runs in four-channel mode or bridges to mono, it fits either a straightforward speaker system or a subwoofer install without swapping amplifiers as the system grows.
