Crunch Ground Pounder with QTD Technology delivers 2500 watts to subwoofers and features include built-in electronic crossovers and includes bass remote. 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 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 after market amplifier power. Operation Mode Mono only Crossover Type Variable Electronic 12dB Per Octave Electronic Equalizer Fully Adjustable 12dB Crossovers Class / Topology Class A/B: High sound quality circuit that allows POWER DRIVE to develop high levels of power with minimal distortion. Output Device Technology Exclusive Crunch SPEED-FET MOSFET components maximize power efficiency while improving sound quality and minimizing distortion. Heat Sink QTD Technology Aluminum: Quick 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 Supply High 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. Bass Remote Included Wired Bass Remote allows adjustments to bass frequencies to be made from the control mounted anywhere in the vehicle.
