The Hifonics A800.4D is a compact four-channel car amplifier rated at 800 watts max, with 4 x 100 watts at 4 ohms, 4 x 200 watts at 2 ohms, and 2 x 400 watts bridged. It uses a Super D-Class full-range design with Ultra-Fi MOSFETs, a low-noise preamp, and variable crossovers on every channel pair. Its small 8.5 x 9.25 x 2.37 inch heatsink and 10 lb weight make it easy to tuck under a seat or behind a panel. It suits drivers powering four speakers or a pair of components plus a sub, and it competes with other compact full-range class D four-channels on channel flexibility rather than raw power.

The Hifonics A800.4D is a compact four-channel car audio amplifier from the ALPHA series. It uses Full Range Super D-Class circuitry and Ultra-Fi MOSFET output devices. It is rated at 800 watts maximum, with low distortion and efficient cooling.
It can run in four-channel mode or as a bridged two-channel amplifier. Built-in electronic crossovers and a bass EQ let you tailor the signal sent to speakers and subwoofers. Inputs include nickel-plated RCA connectors and speaker-level inputs. The amp can turn on automatically from a signal on the high-level inputs, so a remote turn-on wire is not needed.
A heavy-duty aluminum alloy heat sink draws heat away from the MOSFETs. A Pulse Width Modulated power supply keeps voltage constant. Surface Mount Technology construction helps the components withstand shock and vibration. LED indicators on the end panel show overload and speaker short protection. The power, ground and speaker terminals are nickel-plated, use hex screws, and are angled for easier access during installation.
