Our take on the Hifonics LPHA Compact 1200 Watt 1 Ohm Stable Monoblock Car Audio Amplifier

The Hifonics LPHA is a compact Class D monoblock car amplifier built for driving a subwoofer. It is 1-ohm stable and rated at 1200 watts at 1 ohm, 600 watts at 2 ohms and 325 watts at 4 ohms, so it scales with the subwoofer load you wire to it. An electronic variable low-pass crossover keeps bass duties to the sub. It suits drivers who want strong subwoofer power from a small chassis without stepping up to a full-size amp. Against larger monoblocks it trades some headroom and features for a smaller footprint, and its 1-ohm rating lets it pull more from a single sub than many 2-ohm-stable rivals.

Pros
  • 1-ohm stable for high output from one sub
  • Compact Class D chassis saves trunk space
  • Rated 1200 W at 1 ohm, 600 W at 2 ohms, 325 W at 4 ohms
  • Electronic variable low-pass crossover for sub duty
  • Monoblock design simplifies subwoofer wiring
Cons
  • Power output depends heavily on wiring the sub to 1 ohm
  • Single channel only, so it cannot run door speakers
  • Class D amps can be sensitive to electrical supply and grounding
  • Fewer tuning features than larger multi-channel or DSP amps

Questions and answers

What subwoofer impedance should I wire this amp to?
It is rated at 1200 W at 1 ohm, 600 W at 2 ohms and 325 W at 4 ohms. Wire your sub to the lowest impedance it supports to get the most from the amp.
Can this amp power my door speakers too?
No. It is a single-channel monoblock made for subwoofers. Door speakers need a separate multi-channel amp or head unit power.
Is 1200 watts enough for one sub?
That depends on the sub's power rating. Match the amp's 1-ohm output to the sub's RMS handling, and set gain so you do not exceed it.
Does it have a low-pass filter?
Yes. It has an electronic variable low-pass crossover so you can limit the amp to bass frequencies.
Why is it called compact?
It uses Class D amplification, which runs cooler and smaller than older Class AB designs, so the chassis takes less space in the trunk.
Where is the Hifonics LPHA Compact 1200 Watt 1 Ohm Stable Monoblock Car Audio Amplifier cheapest?
