3000 watt Hifonics ALPHA Series Super D-Class® mono subwoofer car audio amplifier with electronic crossovers utilizing Ultra-Fi MOSFETS for high power and effiecent cooling and minimal distortion. Bass remote included. ALPHA car audio from Hifonics brings together the best design and engineering achievements from nearly 4 decades of driving the advancement of car audio. Technological advances like SUPER D-CLASS® and now FULL RANGE SUPER D-CLASS® have given ALPHA amplifiers the Power From The Gods. The SUPER D-CLASS digital chip technology provides extremely efficient, low temperature, high system power in order to run cool from 4-Ohm to 1-Ohm.
LOW NOISE PREAMPLIFIER CIRCUITRY - Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process
RCA INPUTS - Audiophile RCA connectors allow maximum signal throughput with minimum distortion and masximum external noise rejection
OPERATION MODE - Mono mode only
CROSSOVER TYPE - Accu-Cross crossovers allow for complete control of the signal directing to all speakers. See specifications section for specific frequencies
ELECTRONIC EQUALIZER - Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier
CLASS / TOPOLOGY - Developed over 4 decades of engineering to deliver the highest level of sound quality and power efficiency, Hfioncis ALPHA Super D-Class® circuitry results in lower distortion, higher current efficiencies and while producing less heat than conventional amplifier designs
OUTPUT DEVICE TECHNOLOGY - The Ultra-Fi™ MOSFET is designed for music production vs just electronics output power. It produces very musical high power with high efficiency for cooling and minimal distortion
HEAT SINK - Heavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled
POWER SUPPLY - The Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices
OUTPUT CONNECTIONS - Nickel-plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
CONNECTION TYPE - Secure connection for all power, ground and speaker connections. Angled for ease of access during installation.
LED SYSTEM PROTECTION CIRCUITRY DIAGNOSTICS - Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel
BASS REMOTE INCLUDED - HFR-31 Wired Bass Remote allows adjustments to bass frequencies from the control which can be mounted anywhere in the vehicle. Smooth potentiometer and ringed illumination in a satin black mount create a custom look
PHASE ADJUSTMENT - Phase 0-180° Bass drum attack, snap requires phase between deep frequency subwoofers and upper midbass speakers. Fat man/Skinny man, must arrive at your ear at the same time or bass sounds muddy
AUTO TURN-ON - The amplifier detects a voltage rise (6 volts) with a "DC Offset" over the connected input signal on the HIGH LEVEL INPUTS when the head unit or source unit is switched on. Thus, the amplifier will also be turned on. When the source unit is turn off the amplifier is also turned off. Using this feature eliminates the need to use the REM (turn on wire). The AUTO TURN-ON function will work with 90% of all source units because they are equipped with "high power" output. Only a few holder head units will not use this function
300KHZ HIGH SPEED PULSING - The switching speed of the Class D chip puts the amplifier sampling frequencies at over 100 times higher than human ears can hear. This means that the amplifier and the very fast digital switching remains un-hearable in the audio bandwidth for music.
