This is a single channel (Monoblock) Class-D car audio amplifier which comes with a remote bass knob so that you can control amp gain easily. Besides great tech qualifications- this product comes with plexiglass bottom & LED logo on top that gives it a great outlook while working.


  1. MOSFET PWM (Pulse Width Modulated) power supply
  2. Soft turn on circuitry
  3. 1 ohm stable mono operation
  4. Thermal, DC offset, overload and speaker short protection inbuilt
  5. Nickel plated tiffany style RCAs, thus low resistance inputs to the amp
  6. LED power and protection indicators
  7. It comes with Remote Bass Knob; therefore allowing you to control power on/off or subwoofer bass level easily
  8. This is a purely Class-D amplifier where the audio amplification is solely controlled by electronic amplifying switches inside; making the gain much more effective and enthusiastic
