Excellent audiophile amplifier. I've had many different amps for my front tweeters and midrange speakers, ranging in price from $170 to $700. What is the difference between Sony and them? In addition to very good detail, this amplifier has a very comfortable and realistic sound. All images on the stage are correctly placed. Before Sony, I had a Focal FPX 4.400 SQ installed, which costs more than 2 times, but I like the sound of Sony more. I think the price of this amplifier is not high today, because it is really a small gem with an audiophile sound.

The XM-GS4 is small in size and well laid out. A soft glowing white power light sits atop the amp. Testing with short circuits produced immediate shutdown of the amp and a red protection light. Restarting the amp cleared the fault for normal operation to resume.The test vehicle includes a component set of Pioneer TS-Z65CH speakers with a sensitivity of 85 db and full sound deadening. Amp gain was set to produce an output current of 16.5 amps with a 100hz test tone. At slightly over 1/2 volume the XM-GS4 hit the maximum output for my comfort level. This amplifier has plenty of power. Frequency response was even, midbass was dynamic, imaging was excellent, vocals were airy. You would be hard-pressed to find any faults with this amplifier.

I love love love this amp.My unit was an open box and appeared unopened. This amp also won an amplifier shootout, besting amps which cost far more in a blind test.

The Sony amp has no problem making deep bass, the midrange is smooth and the treble is airy. Great amp for any driver. Bridge it for strong midbass drivers. Use another Sony gs4 for midrange and tweeters. You will love it. No noise, hiss or engine whine.
Very good amplifier... Highly underrated. Using it on a 4-way active installation with Morel Virtus.
Product arrived boxed nicely upon opening the package I discovered a fantastic looking amp with a build quality that matched the tier and specs of this amp I m running this amp to a pair of alpine type s components in the front and a pair of precision power 10 inch pro audio speakers in the deck of my 2015 Ford Fusion I bridged the rear Chanel s and run Low pass and the front to channels on high pass this amp pumps out plenty of power to drive deep bass and clear highs with no distortion at high volume this was an upgrade over the smaller 300 watt alpine this is replacing Also I m running this amp on the supplied speaker input converter plug and factory head unit and the remote sensing feature works amazing ultra quick response and turn on this amp is a Hidden Jem ... MoreProduct arrived boxed nicely upon opening the package I discovered a fantastic looking amp with a build quality that matched the tier and specs of this amp I m running this amp to a pair of alpine type s components in the front and a pair of precision power 10 inch pro audio speakers in the deck of my 2015 Ford Fusion I bridged the rear Chanel s and run Low pass and the front to channels on high pass this amp pumps out plenty of power to drive deep bass and clear highs with no distortion at high volume this was an upgrade over the smaller 300 watt alpine this is replacing Also I m running this amp on the supplied speaker input converter plug and factory head unit and the remote sensing feature works amazing ultra quick response and turn on this amp is a Hidden Jem buy one now!!!!!
Works Great!! Sounds great! Great deal Thanks!!
I have owned many amps from 5 channel to mono. 800 to 100 dollar. Idk if you have a fat wallet or one with lent. Best 4 channel Ive ever owned. I live in Oklahoma were are weather is garbage freezing in the morning and sweating by 2. This amp can take whatever you throw at it and then some. Rated 70 or 80 rms per channel. It gives you all of it. You wont be disappointed.
