Our take on the Hifonics A1200.1D 1200 Watts Max 1 Ohm Stable Monoblock Car Audio Amplifier

The Hifonics A1200.1D is a compact Class-D monoblock subwoofer amplifier from the Alpha series. It is rated at 325 watts RMS at 4 ohms, 600 at 2 ohms and 1200 at 1 ohm, with a 10–250 Hz response and a wired bass remote in the box. Its small aluminum heatsink and 8 AWG terminals suit tight installs, and the 1-ohm stability lets one amp drive a pair of dual-4-ohm subs. Against pricier monoblocks it gives up bridgeability and finer tuning, and owners report it makes its rated power but is sensitive to clean wiring and good grounds.
