Our take on the Pioneer GM-X364

by Robert Ferency-Viars

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Pioneer's GM-X364 amplifier delivers multichannel versatility and slammin' sonic performance! Lightning-quick MOSFET power supplies react instantly to changes in the music, for exceptional accuracy. Pioneer builds in front and rear high-pass/low-pass crossovers (80 Hz at 12 dB per octave) so you can tailor the amp's output for full-range speakers, components, or subwoofers. Speaker-level inputs permit connection to any system (even a factory radio), while preamp outputs pass signal to another amplifier in your system.

  • 2-, 3-, or 4-channel output
  • Tri-way capable (Tri-Way crossover required)
  • 35 watts RMS x 4 at 4 ohms
  • 40 watts x 4 at 2 ohms
  • 70 watts x 2 in bridged mode
  • MOSFET power supplies
  • requires 10-gauge power and ground leads — wiring and hardware not included with amplifier
  • front and rear selectable low-pass/high-pass crossover, 80 Hz at 12 dB/octave
  • input level control (0.4V-6.5V)
  • preamp- and speaker-level inputs
  • preamp outputs
  • 12-1/8"W x 2-3/8"H x 11-1/16"D
  • 1-year warranty

Inputs and Outputs


Cosmetics: The amplifier is gray with a black Pioneer logo and black lettering. The side panels are blue with gray lettering. 

Internal Crossovers: There are two separate crossovers, one for CH A and one for CH B. Each built-in crossover can be set for high-pass or low-pass operation, or turned off for full-range output. Each crossover is fixed at 80Hz and has a slope of 12dB/octave.


Right Side of Amplifier:

  • 2CH/4CH Switch: allows you to set the amplifier to work with a 2- or 4-channel input
  • CH A Crossover Switch: allows you to select high-pass, low-pass, or full-range operation for the crossover
  • CH A Gain Control: allows you to adjust the input sensitivity of the CH A preamp inputs from 0.4 to 6.5 Volts
  • CH B Crossover Switch: allows you to select high-pass, low-pass, or full-range operation for the crossover
  • CH B Gain Control: allows you to adjust the input sensitivity of the CH B preamp inputs from 0.4 to 6.5 Volts

Top of Amplifier:

  • Power LED: illuminates in red when the amplifier is on and receiving power

Inputs and Outputs

Right Side of Amplifier:

  • CH A Speaker Input: 4-pin male jack for use with supplied speaker-level input wiring harnesses
  • CH A Input: stereo RCA jacks
  • CH B Speaker Input: 4-pin male jack for use with supplied speaker-level input wiring harnesses
  • CH B Input: stereo RCA jacks
  • Output: stereo RCA jacks

Left Side of Amplifier:

  • Power: screw terminal (0.549" wide)
  • GND (ground): screw terminal (0.549" wide)
  • System Control (remote turn-on): screw terminal (0.349" wide)
  • Speakers: screw terminals (each terminal is 0.349" wide). To bridge the amplifier for 2-channel mode, use the left positive from channel A with the left negative from channel B for your left speaker; use the right positive from channel B with the right negative from channel A for your right speaker.
  • Fuse: one 25-amp blade fuse
