Our take on the Sony XM-GS100

by Buck Pomerantz
Sony

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.

Brings you the bass

Sony XM-GS100 330W x 1 Subwoofer Amplifier

You'll get up to 600 watts RMS of bass power with Sony's XM-GS100 mono amplifier driving your sub. For maximum reliability, this compact amp sports a hefty heatsink that shunts off the heat that's generated when the amp's working hard. The XM-GS100 will also protect your subwoofer, with a Dynamic Distortion Suppressor circuit that rounds off the corners of dangerous square waves, minimizing the destructive effects of an overdriven signal.

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 a low-pass filter for keeping high notes away, along with a subsonic filter that helps tune your bass for a ported enclosure so the lowest notes don't get out of control. You can crank up the variable bass boost if you need some more bump. Sony protects this amp with a 3-year warranty, and that says a lot.

Features

Crossover: The low pass crossover is always engaged (cannot be bypassed); the crossover point is continuously variable from 50 to 300 Hz.

Subsonic Filter: The subsonic filter's cutoff frequency is continuously variable from 6 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.

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

Power/Ground Terminals: The power and ground screw terminals are 0.55" wide.

Remote Terminal: The remote turn on screw terminal is 0.36" wide.

Speaker Outputs: There are two pair of speaker output screw terminals, internally shorted together so it's easy to connect two subwoofers. Each terminal is 0.36" wide.

Speaker-level Input Harness: A 4-pin speaker level input harness is included, allowing you to easily connect the amplifier to a factory radio or a receiver without preamp outputs.

Auto Turn-on: When using the speaker level inputs, the amp will automatically turn on when it senses an input signal.

Preamp Outputs: The amplifier features one set of RCA preamp outputs so you can send audio to another amplifier in your system. The preamp outputs are not affected by the built-in crossover.

Note: The preamp outputs are not active when the speaker level input is used.

Quick impressions from the Lab

Comment by Buck Pomerantz Staff Writer - Creative,

Hefty little jewel

Written by Buck Pomerantz, Staff Writer - Creative, on 8/17/2012 5:05:00 PM

The first thing I noticed was the nice heft of the amp — it's pretty heavy for something with a footprint smaller than a piece of letter-size paper. Over half its chassis is heavy heatsink. All the connections are on one side, and they appear to be gold-plated. The adjustment controls are under a cover, which is removable with a Phillips-head screwdriver.

The instructions aren't in a bound owner's manual, but on a large fold-out sheet of paper. Make sure you read them carefully, they can be a little difficult to follow. However, the explanation of the Dynamic Distortion Suppressor feature clearly diagrams how it smooths the corners of square waves to lessen the distortion effects of over-driving the signal.

Sony XM-GS100

Written By Nick, Chicago, Ill on Wednesday, June 26, 2013
 
I agree with Crutchfield. 5 Star amp. 600x2 RMS @ 1 ohm on a 2k watt 1 ohm 10" sub vibrates the seats quite nicely, hums almost in tune with the engine ;-)
Pros:
Easy Installation, Hits Hard, Very nice vibrations. Will push a 2k watt 1 ohm rated sub efficient.
Cons:
None that I have found thus far. Well they could have put 40 amp fuses in it instead of 35 lol.. just joking. ;)

Crutchfield Customer Review (What's this?)
 
I have this amp connected to a stock radio in a 2012 Miata mx5. Low profile so it mounts easily under the passenger seat. Running two(2) bass shakers- one in each seat. WOW!!! THIS ROCKS!!! At first I had it connected to the rear speakers through hi-level input (not enough voltage from rear outs) Then I called Crutchfield and they told me how to check the front speaker lines. Hooked it up! I'm telling you it's a space saver and this AMP IS AWESOME! I am quite impressed.
Pros:
Crutchfield Service and a clean amp
Cons:
need clearer descriptions of bass filters.
