Notify me when back in stock


Crunch Ground Pounder with QTD Technology delivers 2000 watts to subwoofers and includes built-in electronic crossovers.


  • 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
  • Stereo, Bridged Mono or Stereo/Bridged Mono Simultaneously
  • 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.
