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-GS400, specifically, is a 4-channel amplifier that is capable of outputting a CEA Certified 70 watts RMS to four channels at 4 ohms. For setups that require a bit more power, the amplifier is stable down to 2 ohms, providing 80 watts RMS to four channels. In addition, this 4-channel amplifier can be configured to run as a 3-Channel or 2-Channel amplifier by utilizing its ability to bridge its channels. This well-balanced power output and flexibility is a perfect match for most component & coaxial speakers on the car audio market, along with some subwoofers as well.
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.
The XM-GS400 has a removable top panel that conceals independent front and rear 12 dB/octave variable High Pass filter and Low-Pass filter crossovers. To maximize your audio's bass potential the XM-GS400 also features independent, variable 0 - +10 dB @40 Hz bass boost circuit to increase low frequency response. Need help figuring out what all this means? Check out our K-Base Article that discusses these settings, CLICK HERE.
Staying true to its GS Series pedigree, the XM-GS400 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 like old sony
Sounds great. No noise. Nice build quality.
tested at 85x4 @ 4 ohms and 240 x2 bridged by PAS.
Nicely under rated. Reliable and clear A/B power and nice cosmetics (esp for recent sony amp)
I like the gs line.

Great amplifier.
Bought this amp just to try it. I'm impressed. So much so that it's now my "go-to amp" for those customers wanting more power then a head unit can offer. It is physically smaller then I expected which is great for tight spaces. With it's forced air (fan) cooling, I shouldn't have to worry about heat. The noise level is MUCH lower then I was expecting. Even with the gains relatively high (about 3/4) it's dead silent from the drivers seat (car parked in the garage). The sound quality is great. It's a very musical amplifier. Great bass, great mids, great highs. Excellent imaging and sound stage. I like this amp over my Eclipse and even over my JL 300/4 which I've now sold. As for the power. It does every bit of what it's rated to do. I thought, for the price, if I needed more power I'd just get a second one and run them bridged. Not the case. This amp has plenty of power. I run the Alpine SPR 6x9s in the rears and a custom 8" component set with hand made crossovers in the front.

User friendly
The main reason I got this amp was because it has "Auto Turn On" , which I figured would save me time from poking around my 2014 Dodge Avenger. Not only was that TRUE, but I didn't realize until the install that everything else about the amp was going to save me time. The size of the amp made it easy to mount where I was hoping, the TOP mounted knobs made it easy to reach, re-reach and tune. AND BEST OF ALL, the cover makes sure my kid doesn't go in and mess things up! ha. GREAT AMPLIFIER!!! Oh yea, and AWESOME sound quality. It makes my 6x9 sound like I have a subwoofer..which saves me money from actually ahving to buy one!
