More features

All connections are located on one side of the amp, which makes wiring simpler and neater. The tuning controls sit protected under a cover so they won't get inadvertently moved. You'll find a low-pass filter for keeping high notes away, along with a subsonic filter that helps tune your bass for a ported enclosure so the lowest notes don't get out of control. You can crank up the variable bass boost if you need some more bump. Sony protects this amp with a 3-year warranty, and that says a lot.

It WAS a great amp... But...

Ed from Deatsville, AL on 10/5/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

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.

It's a beast!

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

Cons: None

Great little amp.

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.

Features

Crossover: The low pass crossover is always engaged (cannot be bypassed); the crossover point is continuously variable from 50 to 300 Hz.

Subsonic Filter: The subsonic filter's cutoff frequency is continuously variable from 6 to 70 Hz.

Bass Boost: For added low frequency output, the amplifier has bass boost circuits centered at 40 Hz, variable from 0 to +10 dB.

Protection Circuitry: The amp has three protection circuits:

  • Thermal: turns the amp off when the operating temperature is too high
  • Short circuit: turns the amp off when the speaker outputs are short-circuited
  • DC Offset: turns the amp off when it generates direct current

Power/Ground Terminals: The power and ground screw terminals are 0.55" wide.

Remote Terminal: The remote turn on screw terminal is 0.36" wide.

Speaker Outputs: There are two pair of speaker output screw terminals, internally shorted together so it's easy to connect two subwoofers. Each terminal is 0.36" wide.

Speaker-level Input Harness: A 4-pin speaker level input harness is included, allowing you to easily connect the amplifier to a factory radio or a receiver without preamp outputs.

Auto Turn-on: When using the speaker level inputs, the amp will automatically turn on when it senses an input signal.

Preamp Outputs: The amplifier features one set of RCA preamp outputs so you can send audio to another amplifier in your system. The preamp outputs are not affected by the built-in crossover.

Note: The preamp outputs are not active when the speaker level input is used.

Q
If you wire two subs is it 300 watts per sub?
[ Gary  Jun 01, 2018 ]

A
If you properly wire two compatible subs to present the 2 Ohm final load, yes, each sub would get up to 300 watts RMS. https://www.crutchfield.com/learn/how-to-match-subwoofers-and-amplifiers.html?search=matching I hope that helps. My bio: https://www.crutchfield.com/bio/Ryan

It has a remote terminal, so that would need to be wired through, not sure about the second part though

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.
