The Hifonics Zeus Delta ZD-2550.1D is a single-channel Class D car amplifier rated at 2550 watts max, built to drive one subwoofer or a sub setup. Its PWM MOSFET power supply and aluminum heat sink keep it compact and cool for a Class D design, and it adds a bass remote, onboard crossover and DC signal sense turn-on. It suits budget-minded bass builders who want big rated power without a premium brand's price. Against pricier monoblocks it gives up some real-world output and clean-power headroom, and owners note the max rating is not RMS.

Owners generally call it a solid value for the power, praising the bass remote and easy setup. The main complaints are heat and that the advertised wattage is peak, not continuous.
The Hifonics Zeus Delta ZD-2550.1D is a 1-channel, monoblock Class D car amplifier rated at 2550 watts max. It runs in mono only, and it fits any vehicle. Class D design gives high efficiency in a small footprint.
The amplifier uses a PWM MOSFET output stage and a dual-coil pulse width modulated power supply that keeps voltage constant. An aluminum heat sink dissipates heat. Molded connection terminals handle all power, ground and speaker connections. The RCA inputs are nickel-plated and the preamplifier circuit is low-noise.
An onboard electronic crossover and bass control let you tailor the output to your subwoofers. LED indicators on the end panel show overload and speaker short protection status. A 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. A bass remote is included.
