Pioneer GM-A6604 760 Watt Class AB 4-Channel Car Amplifier features:
  • 760 Watts Max Power
  • 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.
  • Remote turn on by auto signal sense, so you do not need to run a remote turn on lead with OEM head-units
  • 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
  • Gold plated screw terminal connections for Power Inputs and Speaker level outputs

  • Continuous Power Output (4 Ω, ≤ 1% THD+N): 60 W x 4
  • Frequency Response: 10Hz to 35kHz
  • Total Harmonic Distortion (4 Ω): < 0.05% (1kHz)
  • Signal-to-Noise Ratio (IHF-A Weighted, at 1 kHz): >95dB

Customer Reviews

Great all around amplifier
Review by
Install (5 star for easy)
This amp proved to better than I though it would. I needed an amplifier to power my interior speakers on my beater. I wanted more power than an aftermarket deck and since I have always liked Pioneer radios I decided why not give their amps a try. I am glad I did, this amp was cheap to buy and easy to install. I have it powering a set of 6.5 inch components and it powers them easily. I connected the rear outputs to a 10 inch sub and am surprised that it has as much power as it does. (Posted on 3/30/2015)
