Hifonics Zeus Delta 1,750 Watt 5 Channel Mobile Car Amplifier, ZD-1750.5D vs Hifonics Zeus ZXX-2400.1D Monoblock Amp

These are two different tools, not two versions of one. The ZD-1750.5D is a five-channel amp that can run your front speakers, rear speakers and a subwoofer from one chassis, so it suits a shopper building or upgrading a whole system. The ZXX-2400.1D is a monoblock built to drive subwoofers only, so it suits someone who already has a separate amp for the speakers or who only wants bass. On build, both use Hifonics' Class D design, PWM MOSFET supplies and aluminum heat sinks; owners of the Zeus line generally report solid output for the size, though the five-channel runs hotter because it packs more channels into one board.

• Choose the Hifonics Zeus Delta ZD-1750.5D if you want one amplifier to power door speakers and a subwoofer together and save wiring and trunk space.
• Choose the Hifonics Zeus ZXX-2400.1D if you already have speaker amplification and want a dedicated, higher-output subwoofer amp with a bass knob.
