ZD-1350.1D [Open Box]

The Hifonics Zeus Delta ZD-1350.1D is a mono Class D amplifier built around a PWM MOSFET power supply that keeps current levels high and steady even as the subwoofer load pulls hard during bass-heavy passages. It pushes 1350 watts at 1 ohm, 675 watts at 2 ohms, or 350 watts at 4 ohms, giving you flexibility in how the subwoofer or subwoofers are wired without changing amplifiers. An onboard electronic crossover with a low pass adjustable from 50Hz to 250Hz lets you tailor the output to the subwoofer instead of running full range, and a subsonic filter from 15Hz to 40Hz cuts frequencies below what the subwoofer can reproduce, protecting the cone from over-excursion. The built-in bass control adds up to 12dB of boost, adjustable from the included remote, so you can dial in more low end from the driver's seat without reaching for the amplifier. A DC signal sense feature lets the amp turn on automatically when it detects a signal on the RCA inputs, removing the need for a separate remote turn-on wire in installs where that wire isn't easily accessible. Nickel-plated RCA inputs resist corrosion, and an aluminum heat sink dissipates heat generated during extended high-power playback. Secure molded connection terminals keep power, ground, and speaker wiring organized and angled for easier access once the amp is mounted.
