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.

Details:
  • 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

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.
