Sony XM-GS100 330W x 1 Subwoofer Amplifier

Natural, detailed sound
This Sony XS-GS1720S component speaker system features incredibly lightweight, mica-reinforced 6-1/2" woofers that are both airy and stiff, so they can produce big sound without warping or distorting. A supple rubber surround supports these woofers, helping to keep them centered during heavy excursion so you enjoy full bass. The high-energy magnet and nimble motor structure drive the cone with precision so the vocals and instruments sound natural.

High-end components
Vibrant highs from separate 1" aluminum dome tweeters mean you'll hear expressive vocals and cymbal work. External 2-way crossovers keep your highs in flawless balance with your mids and lows, and even let you power the tweeters and woofers separately for enhanced performance and efficiency. Mount these tweeters in a good spot, direct them towards your ears, and you'll catch every satisfying detail.

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

These speakers are awesome!! Im feeding them around 100w RMS and they fail to distort. I have them matched with the coaxials of the same line and everything sounds clear as day and is crazy loud!

Pros: Excellent sound! Beautiful looks!

Cons: None

Product Research


Woofer Cones: The XS-GS1720S woofers use an MRC cone (Mica Reinforced Cellular glass fiber composite) to reduce weight and increase rigidity, delivering full bass response.

Rubber Surrounds: For a smoother response and improved durability, each woofer uses a rubber surround.

Tweeters: The tweeters are 1" aluminum domes offering outstanding dispersion and clarity. They can be flush mounted, surface mounted using the angled brackets, or surface mounted using the flat brackets.

Tweeter Mounting Dimensions:

  Frame Width Frame Length Cutout Width Cutout Length Mounting Height Mounting Depth
Flush Mount 2.442" 2.442" 2.027" 2.027" 0.474" 0.919"
Flat Surface Mount 1.848" 1.848" N/A N/A 1.478" Screw Depth
Angled Surface Mount 1.846" 1.992" N/A N/A 1.570" Screw Depth

Note: With any of the mounting brackets the threaded mounting posts can be used to hold the tweeters in place, this adds to the required depth (approximately 1-3/8" for flush mounting, 1-3/8" for flat surface mounting, and 1-1/8" for angled surface mounting).

Crossovers: Each crossover has high-pass and low-pass outputs with a 5 kHz crossover point. The high-pass slope is 12 dB/octave and the low-pass slope is 6 dB/octave. A jumper inside each crossover allows you to set the tweeter output level according to your system requirements and personal preference; choose 0 dB (factory setting) or -3dB. The inputs and outputs are screw terminals; they will accommodate bare wire or spade connectors up to 0.315" wide. There are two mounting holes in the base of each crossover.

Bi-amp Inputs: The 2-way crossover has separate inputs for the woofer and tweeter; this lets you drive the system with dedicated power for the separate speaker elements, instead of sharing power. The input jumper wires are factory installed to short the tweeter and woofer inputs; the jumper wires must be removed and separate input wires used to bi-amp the speakers.

Crossover Dimensions:

  • Length: 4.650"
  • Width: 3.325"
  • Height: 1.282"

Mounting: The woofers can be mounted in a variety of 6-1/2" and 6-3/4" applications.

Specification Note: Sony's rated power spec for the XS-GS1720S is 75 watts (derived using IEC 60268-5 standards). They also list the CEA 2031 compliant RMS power as 120 watts. We've adopted the 75 watt rating simply because it's the more conservative figure.

Hi Jason C, I does sound pretty good, i have to turn the volume up more than i would like. [ Timothy  Sep 29, 2014 ]
I installed them without an amp. I have a cheap Sony 4 channel 52w per channel receiver. I didn't even use the crossover as it would have involved substantial rerouting of the wire harness in the door. They sound fine and the stereo drives them fine. I think I will go back and install the crossovers, though. [ ALAN  Sep 22, 2014 ]
I installed with a factory reciever in my avalanche. Sound is great- was told a aftermarket reciever like yr alpine would be twice the amp. Try it and can add amp later if needed. Have full range of bass to treble. [ Scott  Sep 22, 2014 ]
yes [ joe  Sep 21, 2014 ]
They sound fine without an amp. Obviously you could get more with an amp, but they don't sound bad without. [ KEITH  Sep 21, 2014 ]
I did that and sounds great. Upgrading for a amp soon . [ RYAN  Sep 21, 2014 ]
Jason, I am running these speakers in the front doors of my Honda Accord using only my Alpine receiver to power them. They sound great with clear highs, solid mids and pretty good bass for their size. They might not sound as good if used further from the listener like on a rear tray mounting location.
