  • Our take on the Hifonics A1200.1D Alpha Mono Car Subwoofer Amplifier

    The Hifonics A1200.1D Alpha is a single-channel car amplifier built to drive one subwoofer. It is rated at 325 watts into 4 ohms, 600 watts into 2 ohms and 1,200 watts into 1 ohm, so it covers a range of sub loads from a modest single driver to a low-impedance setup. Tuning is unusually complete for the class: a 30-250 Hz low-pass crossover, a 10-50 Hz subsonic filter, 0-12 dB bass boost at 45 Hz and 0-180 degree phase control. A wired HFR-31 bass remote is included, and it accepts speaker-level input with DC-offset auto turn-on, which helps in factory-radio installs. Against rival mono amps it competes on tuning features and a Class D, MOSFET output design with an aluminum heat sink rather than on brand prestige.

    Pros
    • Rated to 1,200 watts at 1 ohm for a single sub
    • Full tuning set: low-pass, subsonic, bass EQ and phase
    • Wired HFR-31 bass remote included
    • Speaker-level input with DC-offset auto turn-on
    • Class D design with MOSFET outputs and aluminum heat sink
    Cons
    • Mono only, so it cannot power door or rear speakers
    • Low-impedance output depends on a stable charging system
    • Bass boost at a fixed 45 Hz can sound boomy if overused
    • No onboard DSP or preset tuning

    About the Hifonics A1200.1D Alpha Mono Car Subwoofer Amplifier

    The Hifonics A1200.1D Alpha is a mono car audio amplifier built to power a subwoofer system. Its single-channel design suits a dedicated bass section in a vehicle. It is intended for universal installation with compatible wiring, a source signal, and a properly matched subwoofer load.

    It is rated at 325 watts at 4 ohms, 600 watts at 2 ohms, and 1,200 watts at 1 ohm. The amplifier uses Hifonics Super D-Class circuitry and Ultra-Fi MOSFET output devices. A pulse-width-modulated Twin Turbo Coil power supply and a heavy-duty aluminum alloy heat sink help manage heat.

    Tuning controls include a variable low-pass crossover, a subsonic filter, adjustable bass boost, and variable phase. A wired HFR-31 bass remote is included for adjustment from the cabin. The amplifier accepts speaker-level input and can turn on automatically through DC offset on its high-level inputs, without a remote wire.

    Questions and answers

    What subwoofer loads can the A1200.1D Alpha drive?
    It is rated at 325 watts at 4 ohms, 600 watts at 2 ohms and 1,200 watts at 1 ohm. Match the sub's final impedance to one of those loads and keep the gain set so the amp is not clipped.
    Does it work with a factory head unit?
    Yes. It accepts speaker-level input and has DC-offset auto turn-on, so it can switch on from the speaker signal without a separate remote wire.
    What tuning controls does it have?
    A variable 30-250 Hz low-pass crossover, a 10-50 Hz subsonic filter, bass boost of 0-12 dB at 45 Hz and phase adjustment from 0 to 180 degrees.
    Is the bass remote included?
    Yes, a wired HFR-31 bass remote is included and lets you adjust bass level from the cabin.
    Can it power my door speakers too?
    No. It is a mono amplifier meant for a subwoofer. Door and rear speakers need a separate multi-channel amp or head-unit power.
    Will it fit in a tight install?
    It uses a heavy-duty aluminum alloy heat sink and needs clearance for airflow. Leave room around the heat sink and run adequate gauge power and ground wiring.
    Where is the Hifonics A1200.1D Alpha Mono Car Subwoofer Amplifier cheapest?
