Our take on the Hifonics HAC-3000.4D 3000 Watt 4-Channel Car Stereo Amplifier Class D Amp Black

The Hifonics HAC-3000.4D is a four-channel Class D car amplifier rated at up to 3000 watts maximum output. Class D operation keeps it cooler and more efficient than older Class AB designs of similar power, so it draws less from the alternator during long loud sessions. Its four channels can run four speakers, or bridge into two channels to drive subwoofers, which makes it a flexible base for a full system. It suits enthusiasts building a loud, multi-speaker setup who accept that the 3000-watt figure is a peak rating, not a clean RMS number.

Best forDrivers powering four speakers plus a sub stageBudget-minded builds that want high peak powerCustom systems that need bridging flexibilityDaily drivers who play loud for long stretches
Pros
  • Class D design runs cooler and draws less current than Class AB
  • Four channels cover speakers or bridge to subwoofers
  • High peak power rating for the size
  • Rugged black chassis built for car installs
  • Onboard tuning controls for gain and crossover
Cons
  • 3000 watts is a peak figure; clean RMS output is far lower
  • Real power needs a strong charging system and wiring
  • Class D amps can add noise if gain is set poorly

About the Hifonics HAC-3000.4D 3000 Watt 4-Channel Car Stereo Amplifier Class D Amp Black

The Hifonics Colossus HAC-3000.4D is a 4-channel car amplifier with up to 3000 watts of maximum output. It uses Class D amplifier technology, which is designed to run efficiently with less heat and energy loss. The four channels can power speakers and subwoofers.

Questions and answers

Is the 3000 watts RMS or peak?
It is a maximum (peak) rating. Continuous RMS output per channel is much lower, so match speakers to the RMS figure, not the peak.
Can it power a subwoofer?
Yes. Bridge pairs of channels to drive one or two subwoofers, or run all four channels to speakers.
Will it drain my car's electrical system?
At high output it draws significant current. A stock alternator and thin wiring may struggle; upgraded wiring and a healthy battery help.
Does it have a built-in crossover?
Yes, it has onboard tuning controls including crossover and gain adjustment for each channel pair.
What's in the box?
The amplifier and its mounting hardware. Speaker and power wiring are not included and must be bought separately.
