Description:Autotek MEAN MACHINE compact series of car audio amplifiers bring extreme power with PRO-FI™ High Speed MOSFETS and high sound quality with minimum distortion levels. The MM-1525.1D features 1500 watts of power in a 1 Ohm stable monoblock amplifier designed to power a mono subwoofer system. The Class D technology provides extreme power in a smaller footprint. Features & Benefits: Low Noise Preamplifier CircuitMaximum 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 InputsRCA inputs and outputs provide the highest sound quality connection. Operation ModeMono only Crossover TypeOnboard electronic crossover Electronic EqualizerElectronic equalizer provides control of amplifier output with onboard electronic crossover to tailor specific frequencies to speakers and subwoofers. Class / TopologyVery efficient D-Class to drive additional power while remaining a small footprint. Output Device TechnologyMEAN 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. Heat SinkHeavy-duty aluminum alloy heatsink with illuminated logo adds a vibrant display and showcase for every car audio installation. Power SupplyHigh energy PWM (Pulse Width Modulated) power supply provides MAXXimum power with minimal electrical impact. Output ConnectionsNickel-plated brass connectionwith hex set screw terminals allow for secure connection and resist erosion. Connection TypeAngled, Allen Key connectors provide easy access for hand tools allowing a quick and secure connection. Full-Range RCA Outputs for Signal Pass ThroughFull-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 DiagnosticsMonitor overload and speaker short protection with illuminated indicators on the amplifier end panel. Bass Remote IncludedWired Bass Remote allows adjustments to bass frequencies from the control which can be mounted anywhere in the vehicle.
