Bought this amp 3 years ago and with one month out of warranty, I noticed it starting to go in and out. Thought it was possibly a wiring issue. So I checked everything, including hooking up another amp. Not one problem with the replacement amp. So being that this amp had a 3 year replacement warranty on it. It was natural and my luck that this Sony started to have problems. And wouldn't you know about a week after it was cutting on and off, the amp died. The dreaded "red light" of death! So I'm out an amp. Warranty on it a a month before it died. And now I gotta spend more moola to replace it. Other than that, this amp was everything I expected. Real impressed. Until it died of course! Imo, amps should last longer than 3 years. Especially one that I didn't constantly pour the volume juice to! I've had much cheaper amps that lasted longer than most cars I've owned! Hello Rockford Fosgate!
Pros: Sounded great! Did everything I was expecting it to do.
Cons: Went out a month after the 3 year warranty was up. To expensive for problems when it was taken care of. Should of lasted much longer.

Sound quality is excellent. Built like a tank. Pushing a Rockford Fosgate P3 10 inch @ 2 ohms with this amp and it brings out every bit of goodness in the sub. Great amp!
Pros: Sound and build quality

I needed a small amp to drive a pair of Fosgate P2D2 8" subs in a ported box. They are each wired in series to 4 ohms then paralleled to 2 ohms total. I started with an Alpine MRP-M500 (known to be a good amp) then bought the Sony XM-GS400 for my doors. I liked the GS400 so much that I gave the GM100 a try because it matched. I'm impressed. This little Sony does a great job. Better then the Alpine. Looks good. Sounds good. I don't like that Sony used the older style terminals though. They loose 1/2 a star for that and another 1/2 a star for the price. It's a little bit overpriced for a 600w amp but the sound quality may justify that for some. I mentioned the XM-GS400 4ch version. I HIGHLY recommend that amp for your door speakers. It's dead silent at idle (no hiss), crystal clear sound with a great soundstage and dynamics, and does every bit of it's rated power. The GS400 teamed with a GS100 are a perfect match but I'm not a real bass head. I wanted just a little more power to my other speakers (8" in the doors, 6x9" in rears) so I bought another GM400 and run them bridged.
Pros: Small. Clean power. Elegant styling. Easy to use.
Cons: Price. Uses old style terminals.

I agree with Crutchfield. 5 Star amp. 600x2 RMS @ 1 ohm on a 2k watt 1 ohm 10" sub vibrates the seats quite nicely, hums almost in tune with the engine ;-)
Pros: Easy Installation, Hits Hard, Very nice vibrations. Will push a 2k watt 1 ohm rated sub efficient.
Cons: None that I have found thus far. Well they could have put 40 amp fuses in it instead of 35 lol.. just joking. ;)

I have this amp connected to a stock radio in a 2012 Miata mx5. Low profile so it mounts easily under the passenger seat. Running two(2) bass shakers- one in each seat. WOW!!! THIS ROCKS!!! At first I had it connected to the rear speakers through hi-level input (not enough voltage from rear outs) Then I called Crutchfield and they told me how to check the front speaker lines. Hooked it up! I'm telling you it's a space saver and this AMP IS AWESOME! I am quite impressed.
Pros: Crutchfield Service and a clean amp
Cons: need clearer descriptions of bass filters.
