Sony XM-GS100
GS Series Monoblock Subwoofer Amplifier

The new Sony GS series of amplifiers are the perfect way to get a great system in your vehicle. Whether you are expanding into a full-blown aftermarket setup, or are just looking to integrate better overall performance into your OEM setup, the GS Series has you covered. These amplifiers have been purposed-engineered with High Level Inputs - with Auto Turn-On - to integrate into most vehicles with an OEM headunit and also come equipped with Gold Plated RCA inputs for installs with a proper Aftermarket Headunit; both delivering the best possible audio transfer. These GS series amplifiers are also designed with a stylish heatsink and removable cover - which inconspicuously houses a full crossover board.

The XM-GS100, specifically, is a Monoblock amplifier that is capable of outputting a CEA Certified 330 watts RMS at 4 ohms. For setups that require a bit more power, the amplifier is stable down to 2 ohms, providing 600 watts RMS to its one channel. 330 watts is perfect to a setup that aims at being efficient while simply filling in the low end that lacks in many systems. On the other hand, 600 watts is well above 'modest' and is perfect for the individual that prefers sound quality over "SPL" but still wants to "feel" the bass.

Compact 10-3/4

Compact 10-3/4" x 8" Chassis

The Sony GS Series line of amplifiers are purpose-built to be as flexible and user/installer friendly as physically possible - that begins with the amplifiers' small footprint. At 10-3/4 in width, 8" in depth and only 2-1/8" in height, the Sony GS Series is capable of fitting underneath most seats, behind most seats or along the side panel of most trunk cargo areas. This allows you or your installer to build the system in a way that best fits the space provided by the vehicle.

Built-in Crossover

Built-in Crossover

The XM-GS100 has a removable top panel that conceals a fully variable 12 dB/octave Low-Pass filter crossover. To maximize your audio's bass potential the XM-GS100 also features a fully variable 0 - +10 dB @40 Hz bass boost circuit to increase the overall low frequency response. Need help figuring out what all this means? Check out our K-Base Article that discusses these settings, CLICK HERE.

Gold Plated Terminals

Gold Plated Terminals

Staying true to its GS Series pedigree, the XM-GS100 is equipped with gold-plated RCA inputs, speaker-connection outputs and power/ground/REM connections. In addition, all these connections are 'press' screw connects that maximize the area of the cables used. Not only does this insure that the amplifier receives the best possible current/signal, but it also makes sure that your system delivers you with transparent, accurate and high-fidelity audio.

Great Amp.

Perfect little amp that drives a JL stealth box containing a single 10W3v3 and it goes loud and deep and its clean. It sounds so good its ridiculous. Awesome value.

Fantastic amp, will push Competiton.

I have this hooked into a dual 2 ohm Quantum 10" 2000w Competition series woofer with a 180 oz magnet. Also using a Rockford Fosgate capacitor, which seems to be made to work perfectly with this unit. All I can say is wow! I took a gamble purchasing this back when they were selling for 549.99 and bought directly from Sony. Put it to the test, and I just purchased this one at 153.99 prime. Going to use the second one to power the 2 Rockford Fosgate 8" door subs that were ordered with this amp in my Mustang. This amp if used with a capacitor, will push at the very least 1 2000 watt dual 2 ohm competition 10". I have a good friend in the audio buis that also cannot believe the performance I got after install. C-------d also gave this amp a 5 out of a possible 5 score, and has a good review. If your new to the game, C-------d is a good source of information.Hope this helps with your decision, you won't be dissapointed.

Awesome mix of spl and sq!!!!

got this to replace a really old Sony amp powering 2 old Sony 12's. The old Sony still works amazingly (exactly the reason why I stuck with Sony,I know this one is gonna last just as long) I was simply wanting more power and boy does this deliver. Still has all the sound quality of my old amp with a HEAVY dose of spl, actually gets hard to breathe while listening to bass heavy music!!!!Don't believe everything you hear on those audio forums...Sony has high Quality stuff...there's a reason it aint the cheapest!!!

Great Product

This amp is by far the best amp I've ever had. I've had it since 2010 and it is still working perfectly. At the rate it's going it doesn't look like I'll ever need to purchase another one. This amp has plenty of power, especially if you wire your subwoofers down to 2ohms. I highly recommend it.

Thank you Sony.
