  • Our take on the ZD-750.4D

    The Hifonics ZD-750.4D is a four-channel car amplifier from the Zeus Delta line, rated at 750 watts total. It runs in four-channel or bridged mono mode, so it can drive four speakers or two speakers plus a bridged subwoofer. A PWM MOSFET power supply and a low-noise preamp circuit aim to keep current steady and distortion low. It suits budget-minded builds that want one amp for the whole system, though it lacks the DSP tuning and higher clean-power headroom of premium four-channels.

    About the ZD-750.4D

    The Hifonics ZEUS DELTA ZD-750.4D is a four-channel Class D car amplifier with 750 watts of maximum power. It uses a PWM MOSFET power supply with a dual-coil design to keep voltage constant and deliver stable power with minimal heat. The case has an aluminum heat sink for heat dissipation.

    It runs in four-channel or bridged mono mode and can be used full range. An onboard electronic crossover and built-in bass control let you tailor the output to your speakers and subwoofers. The low-noise preamplifier circuit keeps distortion minimal, and the RCA inputs are nickel plated and corrosion resistant.

    The DC SIGNAL SENSE switch turns the amp on when a signal arrives at the RCA inputs, so no remote turn-on wire is needed. This feature can be switched off. LED indicators on the end panel show overload and speaker short protection. Molded, angled terminals handle all power, ground and speaker connections.

    Questions and answers

    Is the 750 watts RMS or peak?
    Hifonics markets the ZD-750.4D at 750 watts total, which is a maximum-style figure. Expect lower clean power per channel in real use, so match it to speakers rated for modest power.
    Can it run a subwoofer?
    Yes. It is bridgeable, so you can bridge two channels into mono for a subwoofer while the other two drive speakers.
    Does it have a built-in crossover?
    Yes. It has an onboard electronic crossover and equalizer to tailor frequencies to speakers and subwoofers.
    What inputs does it use?
    It takes nickel-plated RCA inputs from a head unit. There are no digital or optical inputs.
    Will it fit my car?
    Hifonics lists universal vehicle fitment. Check the mounting depth and space in your install location before buying.
    What is in the box?
    The amplifier itself. Wiring and installation hardware are typically sold separately, so plan for an amp kit.
