  • Pulse Width Modulated MOSFET Power supply
  • Compact Design for Versatile Installation Options without compromising sound quality, Efficient Class-AB digital Car Amplifiers are 50% smaller that the Pioneer GM-Series Car Amplifiers.
  • Improved Protection circuit senses internal temperature and automatically lowers input level to prevent heat damage. Stability circuitry allows connection to 1 ohm subwoofer systems which allows connection of large or multiple subwoofers.
  • Variable Low Pass filters and high pass filters allow you to adjust the playback frequencies from 40 Hz to 500 Hz with 12dB per octave slopes
  • Speaker level inputs allow you to connect this Car Amplifier stereo system that do not have RCA outputs. The is very typical for OEM head-units and you can now avoid adding separate line level converters.

  • 2 channel RCA inputs accepts up to 6.5 volt input signals
  • RCA Pass through outputs to connect multiple amplifiers in series
  • Bass boost 0-18dB
  • Gold plated screw terminal connections for Power Inputs and Speaker level outputs

Great purchase

I wanted an amplifier that had some extra power. I have this connected to a home built 3-way front stage and needed a low cost amp to do the trick. This amp is an excellent low cost choice, the audio quality is great, doesn't lack any power, and soundstage and clarity are excellent. I am really surprised that the audio quality was as good as it is. (Posted on 3/30/2015)
