|Low Noise Preamplifier Circuit
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 and outputs provide the highest sound quality connection.
Onboard electronic crossover
Electronic equalizer provides control of amplifier output with onboard electronic crossover to tailor specific frequencies to speakers and subwoofers.
|Class / Topology
Very efficient D-Class to drive additional power while remaining a small footprint.
|Output Device Technology
MEAN MACHINE'S ROAD WORTHY™ TCID (Twin Coil Isolation Design) and PRO-FI™ High Speed MOSFETS bring extreme power with high sound quality and minimum distortion levels.
Heavy-duty aluminum alloy heatsink with illuminated logo adds a vibrant display and showcase for every car audio installation.
High energy PWM (Pulse Width Modulated) power supply provides MAXXimum power with minimal electrical impact.
Nickel-plated brass connectionwith hex set screw terminals allow for secure connection and resist erosion.
Angled, Allen Key connectors provide easy access for hand tools allowing a quick and secure connection.
|Full-Range RCA Outputs for Signal Pass Through
Full-range signal pass through output allows additional amplifiers to be run from the "output" RCA connections which minimize the need for additional cables running the length of the vehicle. This can dramatically minimize noise.
|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.
