Our take on the Hifonics Zeus Delta 750 Watt 4 Channel Mobile Car Amplifier, ZD-750.4D

The Hifonics Zeus Delta ZD-750.4D is a compact four-channel Class D car amplifier rated at 750 watts max. It runs full range and can be bridged, so it can drive four speakers or two speakers plus a bridged subwoofer pair. Class D and a PWM MOSFET supply keep it small and cool compared with older Class AB four-channels of similar rating. It suits budget builds that want one amp for the whole system, and its DC signal sense lets it turn on without a remote wire.

About the Hifonics Zeus Delta 750 Watt 4 Channel Mobile Car Amplifier, ZD-750.4D

The Hifonics Zeus Delta ZD-750.4D is a 4-channel Class D car amplifier with 750 watts of maximum power. It runs in four-channel, full-range, bridgeable mode and fits any vehicle. The Class D design delivers high efficiency in a small footprint.

It has a PWM MOSFET power supply with a dual-coil design that keeps voltage constant. The aluminum heat sink dissipates heat. A low-noise preamplifier circuit and nickel-plated RCA inputs handle the signal. Molded connection terminals take all power, ground and speaker connections.

An onboard electronic crossover and a built-in bass control let you tailor the output to your speakers and subwoofers. LED indicators on the end panel show overload and speaker short protection. The DC signal sense switch turns the amp on when it receives a signal on the RCA inputs, so no remote turn-on wire is needed.

Questions and answers

Is the 750 watts RMS or max?
It is a max rating for the whole amp. Expect much lower continuous power per channel, so check the RMS figures before matching speakers.
Can it power a subwoofer?
Yes, if you bridge two channels. Bridging pairs channels into one stronger output, so a four-channel amp can run two speakers and one bridged subwoofer.
Do I need a remote turn-on wire?
Not necessarily. The DC signal sense switch lets the amp turn on when it detects a signal on the RCA inputs.
What size is it?
It measures about 7.32 by 5.75 by 2.16 inches and weighs around 3.8 pounds, so it fits in tight spaces.
Does it work with any car?
Fitment is universal. It works in any vehicle with a 12-volt electrical system and the wiring to support it.
