Sony XMGS4 GS Series 4/3/2 Channel High Less Amplifier (Black)

I’m installing this in my 1997 Jeep Wrangler (TJ) because my old one bit the dust. The packaging was of good quality and the size of this amp is considerably smaller than my old one. Only time will tell how this amp does. I mean... it’s going into a Jeep whose owner rides the majority of it with the windows off. Update: Wow! I can’t believe how much better the audio sounds. Now I can actually hear what I’m listening to. Perfect. Mine fits snugly underneath my passenger seat.i just drilled some pilot holes before I screwed the unit into the metal.

We’ve had sound systems installed in our vehicles over the years. This amp hangs with the best of them; the sound quality is amazing and very detailed. Make sure to get quality speakers installed.

Item arrived as described and I am satisfied with purchase.

I love the sound of this amp one of the best sounding amps I’ve heard on mid and highs I’ve been in car audio for over 30 years,the build quality is great my only gripe with this amp is the wire terminals I have it powering 2kicker 6.5 components in my 2007 Yukon xl and the sound is clear and articulate all I can say is great job Sony 👍🏾

1. The output transistors are A1908 , C5100 these are high speed Japanese transistors designed for audio use mostly found in the classic Japanese amps . 2. The Input is single stage (Not double differential input stage) It is not a a fully complimentary amplifier but the design will meet all car audio applications . 3. The component selection of Mosfets , High Speed Diodes & Inductor of the voltage step-up circuit is good and robust with a clean output . There is not much buffer capacitance on the power lines , how-ever Sony has kept space for a larger capacitor on the PCB should someone would like to upgrade it . 4. PCB design and quality is good and handling of high current lines have been done well . 5. The chassis is well designed and robust , facilitates opening of the Amp easily to service common parts and has a built in fan cleverly placed . 6. The cross over circuit is good and works well and is of a practical design , it uses smd components , smd is yet not very well accepted in high end audio due various audio requirements . However ' The DC offset measured was 16mv on 3 channels and 32mv on one channel . The Amp is easy to set up and flexible with regard to input / output . Sound Quality --- I have a 4 way Active cross-over setup and this Amp for Mid range and human ear is most susceptible to distortion in the Mid range. The Amp plays clean with a warm sound in the lower mids and an accurate response all over . (Bench-marked using own made 8inch Mid Drivers X 8 units & Tannoy Dual Co-concentric x 12 units ) This is a very good Amp at it's price range and recommend it .
