Our take on the Hifonics A1200.4D Alpha Series Compact 1200 Watt 4-Channel Car Amplifier

The Hifonics A1200.4D is a compact four-channel Class D car amplifier rated at 1200 watts peak. It uses Super D-Class circuitry and Ultra-Fi MOSFETs, runs cool, and is stable from 4 ohms down to 1 ohm, so it can drive four speakers or be bridged for subwoofers. Electronic crossovers let you tune front, rear and sub channels separately. It suits budget-minded builds that want a lot of power in a small footprint, though its peak-watt rating is more marketing than measured RMS output, and rivals in its class publish cleaner RMS figures.

Questions and answers

Is 1200 watts RMS or peak?
It is a peak rating. Continuous RMS output per channel is much lower, so match it to speakers by RMS power, not the headline number.
Can it run a subwoofer?
Yes. Bridge two channels into one for a sub, or run all four channels to speakers and bridge the rear pair.
What impedance can it handle?
Hifonics rates it stable from 4 ohms down to 1 ohm per channel in Super D-Class mode.
Does it have crossovers?
Yes, it has built-in electronic crossovers so you can set high-pass and low-pass points per channel pair.
Is a bass knob included?
No bass remote is listed for this model; adjust bass through the amp's controls or your head unit.
How much power do I need to feed it?
Plan for a stout power and ground wiring kit and a charging system that can supply the current the amp draws at full output.
