Description: Crunch Power X with SPEED-FET Output and QTD Technology delivers 1000 watts to front and rear speakers features built-in electronic crossovers.Features: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 Low voltage RCA Inputs: Highest sound quality connection with quality RCA materials helps prevent interference and minimize distortion in the signal path. High Level Inputs Easily tie into OEM audio systems that do not offer RCA output to maximize aftermarket amplifier power. Operation Mode Four Channel Stereo, Dual Stereo Bridged, Stereo + Bridged Mono, Dual Bridged Mono Crossover Type Fully Adjustable 12dB Crossovers Electronic Equalizer Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Class / TopologyHigh sound quality circuit that allows POWER DRIVE to develop high levels of power with minimal distortion. Output Device TechnologyExclusive Crunch SPEED-FET MOSFET components maximize power efficiency while improving sound quality and minimizing distortion. Heat SinkQuick Thermal Dispersion Technology assures additional mass in the aluminum heat sink keeps the amplifier running cool with nearly undetectable distortions during normal music listening. Power SupplyHigh energy Pulse Width Modulated Power Supply delivers power with minimal impact on the electrical system. Output Connections. Nickel Plated Brass Connection with terminals allow for secure connection while resisting corrosion. Connection Type Screw Down Connectors: Easy access for hand tool allowing a quick and secure connection. LED System Protection Circuitry Diagnostics Monitor overload and speaker short protection with lighted indicators on the amplifier end panel.
