2000 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.
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.
(Manufacturer # A2000.1D )
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
Nickel plated RCA connectors for audiophile signal quality and maximum signal throughput with minimum distortion and maximum external noise rejection
Mono mode only
Accu-Cross crossovers allow for complete control of the signal directing to all speakers. See specifications section for specific frequencies
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, Hifonics 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
Heavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled
The Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices
Nickel plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
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
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
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
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
With Surface Mount Technology the typical "through-hole" placement and the larger tolerances from human placement is dramatically improved. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components.
Because of their lower mass SMT components withstand shock and vibration making them perfect for audio designed for all vehicles.
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.
When comparing the innovative ALPHA designs to traditional Hifonics amplifier layouts, the difference is amazing. Pictured below are the BRUTUS BXX3000.1D and the ALPHA A3000.1D amplifiers with their heatsink difference clearly illustrated. The ALPHA footprint is reduced by 25% over standard Hifonics amplifiers. The engineers accomplish this without any reduction in aluminum mass-to-power ratio.
The four channel BXX-800.4 comparison is equally as startling when compared to the A800.4 ALPHA.
Super D-Class® & Full Range Super D-Class®
With four decades of Hifonics engineering and innovation, ALPHA series amplifiers have the best of every amplifier component completely redesigned and re-engineered. This intense design engineering and circuit design has led to very low noise sound quality pre-amplifier sections with electronic components with minimal crosstalk. This is all accomplished with surface mount component and thick PC boards. The crossovers have been redesigned to maximize sound shaping controls across all amplifiers.
The biggest change which is an ALPHA exclusive is the voltage matched, tight tolerance and hand selected components which are marked as proprietary with the Hifonics logos, visible only when the bottom is removed or when on display with an ALPHA retailer. This assures that you are getting components selected by Hifonics engineers for the ALPHA series and nowhere else on the planet.
ALPHA 2 and 4 channel amplifiers have a feature to make integration with a factory radio or source unit really easy. The amplifier will sense when a signal voltage rise through the connected input wires which travels through the RCA’s. This means that you can easily integrate the ALHPA amplifier into an OEM installation without spending additional money on a Line Output Converter (LOC).
Five Channels in a Single Amplifier
The ALPHA line has a Hybrid. Due to the incredible engineering of the circuit layout and the high power components being layout in a way that high power/high voltage cross talk are minimized, the team has been able to accomplish a 5 channel ALPHA Amplifier which maximizes efficiency and minimized any electrical interference.
One Amp Powers It All
All that power packed in one amplifier makes system design a breeze. Easily integrate into your OEM system using all 5 channels of ALPHA power with ALPHA speaker’s front and rear with an ALPHA subwoofer. Simple in concept but shocking in the sound it will deliver.
Sound Control Through Engineering
Additionally, all ALPHA amplifiers feature:
Ultra-Fi™ MOSFET - Produces high power with minimal distortion
T3 (Twin Turbo Toroid) power supply torroids
Pulse Width Modulated MOSFET Power supply
All Mono and five channel amplifiers include an HFR-31 bass remote to put the bass control at arm’s length. The amplifiers protection condition is also shown by blue illumination for normal operation and red for a short being present that requires the attention of an installer.
