About the Sony XM-GS400
Brings you the music
Brings you the music
You'll get 70 watts RMS to each of your front and rear speakers with Sony's XM-GS400 4-channel amplifier driving your system. 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.
More features
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.

Protection Circuitry: The amp has three protection circuits:
- 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
- DC Offset: turns the amp off when it generates direct current
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.
Power/Ground Terminals: The power and ground screw terminals are 0.55" wide.
Remote Terminal: The remote turn on screw terminal is 0.35" wide.
Speaker Outputs: Each speaker output screw terminal is 0.37" wide.
Speaker-level Input Harness: An 8-pin speaker level input harness is included, allowing you to easily connect the amplifier to a factory radio or a receiver without preamp outputs.

By adding this 4-channel amp to my speakers(which are Sony as well) it brings life to the music life like never before. I can hear the highs crisply, punchy mid bass(especial with no filter or low pass filtering). Easy installing and great features to fine tone to your personal preferences.
