Crunch POWER X incorporates full Class A/B technology in stereo and four channel amplifiers along with Class D in the mono. Class A/B sounds better, but the PC boards require a bit more space that in other circuit topologies. With Crunch POWER X we have trimmed away some of the more esoteric features to deliver a great amplifier that sound like you would expect Crunch to sound.

The POWER X line also includes Crunch technology like QTD (Quick Thermal Dispersion) Technology which puts more aluminum on the heatsink than a normal amplifier. QTD assures the amplifiers make huge power while running very cool with nearly undetectable musical distortions.

Features & Benefits
  • 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/Topology
    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
    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.
