  • 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.

  • 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.

  • Bridge mode allows to run this as a three channel or two channel amplifier
  • 4 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

  • Continuous Power Output (4 Ω, ≤ 1% THD+N): 40 W x 4
  • Frequency Response: 10Hz to 35kHz
  • Total Harmonic Distortion (4 Ω): < 0.05% (1kHz)

Customer Reviews

Perfect amp for my 5x7's
Review by
Install (5 star for easy)
I needed an amp to run my Pioneer 5x7's in my Ford truck and didn't want to spend a bunch of money. This amp is perfect and has plenty of power for my Pioneer 5x7"s. For under $300 I have an entirely new audio system! Thank you Quality Mobile Video for the recommendations! (Posted on 3/30/2015)
