hifonics A1200.1D ALPHA Super D-Class 1200 Watt Monoblock Car Amplifier

SKU CH-SAK7-DGSCZ

A 1200 watt mono subwoofer amplifier with Super D-Class circuitry, electronic crossovers, bass remote and MOSFETS for efficient cooling

  • 1200 watts at 1 ohm for powerful bass
  • Super D-Class circuitry runs cooler and more efficiently
  • Variable low-pass crossover 30-250 Hz tailors subwoofer output
  • Bass boost 0-12 dB at 45 Hz adds punch
  • Wired bass remote included for convenient level control

Purpose and audience

The hifonics A1200.1D ALPHA is a Super D-Class mono subwoofer amplifier built for car audio systems that need up to 1200 watts at 1 ohm. It suits installers who want a single-channel amp with electronic crossovers and a bass remote for subwoofer control.

Interface limits

The amp accepts speaker-level inputs and RCA signals from 0.2V to 6V, with a frequency response of 10Hz to 250Hz. Its variable low-pass crossover operates from 30Hz to 250Hz at 12dB per octave, while the subsonic filter covers 10Hz to 50Hz and bass boost reaches 12dB at 45Hz.

Installation notes

Power terminals use 8 AWG for 12V and ground, with 24 AWG also noted, so cable gauge must match those specifications. Mono-only operation means it cannot drive stereo speakers, and the variable phase shift of 0 to 180 degrees must be set correctly to avoid cancellation with other subs.

Questions about this item

Should I wire my subwoofer at 1 ohm, 2 ohms or 4 ohms with this amplifier?

The amplifier delivers 1200 watts at 1 ohm, 600 watts at 2 ohms and 325 watts at 4 ohms; choose the impedance that matches your subwoofer's rating and your desired output level

What does the 1200 watt rating actually mean for daily listening?

1200 watts is the maximum power at 1 ohm; at 2 ohms the amp produces 600 watts and at 4 ohms 325 watts, so real-world output depends on your subwoofer's impedance

What speaker wire gauge do the power terminals accept?

The 12 V and ground terminals accept 8 AWG wire, while the speaker terminals accept 24 AWG wire
