Or you can switch the amp into 2-channel mode to power a couple of subs with 160 watts RMS each. This compact amp sports a hefty heatsink that gets rid of the heat that's generated when you're pushing your system hard. The XM-GS400 also uses a cooling fan, which automatically adjusts its speed for the heat it detects, ensuring this small amplifier will always produce the power that's expected.

Sony's XM-GS100 4-channel amplifier

All connections are located on one side of the amp, which makes wiring simpler and neater. The tuning controls sit protected under a cover so they won't get inadvertently moved. You'll find separate controls for the front and rear channels on this versatile amp. You can run two speakers and a sub, for instance, and have the correct high-pass, low-pass, and subsonic filters available to get the tone right. You'll appreciate the bass boost, if you need a little extra punch. Sony protects this amp with a 3-year warranty, and that says a lot.

Features

Overview: The XM-GS400 is is a four channel amplifier with independent controls for the front and rear sections. Both the front and rear sections are bridgeable, so the amp can be used in 4-channel, 3-channel, or 2-channel mode.

  • Thermal: turns the amp off when the operating temperature is too high
  • Short circuit: turns the amp off when the speaker outputs are short-circuited

Crossover: The front and rear sections of the amp have independent crossover controls:

  • Mode: 3-position switch; Low Pass, Off (crossover is bypassed), High Pass
  • Frequency: 50-300 Hz; continuously variable

Subsonic Filter: The front and rear sections of the amp also have independent subsonic filter controls. The cutoff frequency is continuously variable from 6 Hz to 70 Hz.

Bass Boost: For added low frequency output, the amplifier has bass boost circuits centered at 40 Hz, variable from 0 to +10 dB. There are separate bass boost controls for the front and rear amplifier sections.

Remote Terminal: The remote turn on screw terminal is 0.35" wide.

Speaker Outputs: Each speaker output screw terminal is 0.37" wide.
