Our take on the Sony XM-4060GTX

by Tim Sprinkle
Sony

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Sony knows that a steady power source is the foundation of a great sound system. That's why they design their Xplod amplifiers to deliver consistent output to maximize power distribution to your speakers. Pulse power supplies guarantee that this amp will maintain consistent output, regardless of fluctuations in the voltage from your car's electrical system, while MOSFET power supplies keep everything running efficiently.

Powering a component speaker system? At 60 watts RMS x 4 channels, the XM-4060GTX has the power and flexibility you need to get your front and rear speakers sounding great. Or you can switch to 3-channel mode — bridge the rear channels, sending 150 watts RMS to your subwoofer, while the front two channels (60 watts RMS x 2) power your front speakers.

Built-in variable high- and low-pass crossovers let you tweak the frequencies you send to your speakers, protecting them from damaging distortion. A variable bass boost (0-10dB at 40 Hz) lets you crank up a little extra low-end thump. Gold-plated terminals give you reliable signal and power connections, and speaker-level inputs allow for easy integration with any system.

Features

Channel Configuration: The XM-4600GTX amplifier can operate in a 4-channel mode, or, by bridging the rear channels, operate in a 3-channel mode. You cannot bridge the front channels on this amplifier.

Protection Circuitry: This amplifier has 3-way protection circuitry which protects the amplifier in the following cases:

  • Thermal: shuts off the amp when the operating temperature is too high
  • Short circuit: shuts off the amp when the speaker outputs are short-circuited
  • DC Offset: shuts off the amp when the speaker wires or ground lead is not securely connected, generating direct current

Power/Protector LED: The amplifier has an LED on the top panel which glows green when operating normally, and changes to red when the protection circuit is activated.

Built-in Crossovers: The XM-4600GTX amplifier has the following built-in crossovers:

  • Front Channels: High-pass filter, continuously variable from 50-300Hz, with a slope of -12dB/octave. With the filter switch, you can select high-pass or "off" for full-range operation.
  • Rear Channels: Low-pass or high-pass filter, continuously variable from 50-300Hz, with a slope of -12dB/octave. With the filter switch, you can select low-pass, high-pass or "off" for full-range operation.

Low Boost: The front and rear channels have independent bass boost controls, allowing you to add up to 10dB of boost centered at 40Hz.

Level Control: This amp has independent level controls for the front and rear channels.

Protection Cap: The XM-4600GTX comes with a plastic protection cap that fits over the power/ground/remote terminals, helping to prevent accidental short circuiting.

Inputs and Outputs Notes

Power/Ground Terminals: The power and ground screw terminals are 0.54" wide to easily accommodate up to 4-gauge wire.

Speaker-level Input Harness: The amp comes with a 4-channel speaker-level input harness with an 8-pin Molex plug on one end. This allows you to more easily connect this amplifier to a factory deck or a receiver without preamp outputs.

Bridging the Amplifier: When bridging the amplifier's rear channels, the subwoofer's speaker wires are connected to the left positive and right negative speaker terminals.

Specifications

RMS Power Output (supply voltage at 14.4 Volts):

  • Four speakers:
    • 60 watts x 4 into 4 ohms (20Hz to 20kHz, 0.08% THD)
    • 75 watts x 2 into 2 ohms (20Hz to 20kHz, 0.1% THD)
  • Three speakers:
    • 60 watts x 2 + 150 watts x 1 into 4 ohms (20Hz to 20kHz, 0.1% THD)

Maximum Power Output:

  • Four speakers:
    • 120 watts x 4 into 4 ohms
    • 150 watts x 2 into 2 ohms
  • Three speakers:
    • 120 watts x 2 + 300 watts x 1 into 4 ohms

Current Drain: at rated output: 31A (at 4 ohms)

Wiring Recommendation

Amplifier Wiring: This amplifier uses two 25-amp fuses, so its total fuse rating is 50 amps. The Streetwires 8-gauge amp wiring kits (item #s 211PS8B, 211PS8R, 211PS8BI, 211PS8RI) include a 60-amp fuse, which will accommodate the amp's fuse rating. Some 4-gauge wiring kits also include a 60-amp fuse (Scosche--142AKPA14, Rockford Fosgate--575CP4CKDS). Other 8-gauge amp wiring kits carried by Crutchfield include a 40-amp fuse. If you are using an 8-gauge amp wiring kit with a fuse rated less than 50 amps, the fuse should be replaced with a 50-amp AGU fuse (item #s 211AGU50, 142P50F4I).

Crutchfield Customer Review (What's this?)
 
This amp will give you plenty of options for a variety of speaker set ups...I put it in a Ford Ranger pickup with one 12 in Sub and powered the other 4 speakers in the truck with it as well...The input level controls give you plenty of room to power my factory speakers, by turning the levels down and not blowing them, and then once i upgrade i can feed them a little more power and still maintain pure crisp clean sound....All in all a great amp, as posted before it is big but with some creative thinking you can find a place to put it....

Better than expected

Crutchfield Customer Review (What's this?)
 
This amp was an addition to my system and works great. The only drawback is it is BIG but it well worth it. Has all the right controls built into the amp. Good choice if you are looking for a good 4 channel amplifier as a second source or it's powerful to be a decent primary one. Would recommend this product.

This is a great amp if you're looking increase the sound quality coming from your after-market speakers. It has a good amount of power and easily provides the recommended RMS power to most speakers. Adjustable high pass filters are excellent. Bass boost is nice if you don't have a sub. Although it is kind of big, it's pretty thin and fits easily under my front seat.

My current system -
Head unit: Sony CDX-F7710X
Front Speakers: Pioneer 6.5" 4-ways
Rear Speakers: Sony 6x8" 4-ways
Amp: Sony 600W 4-channel
Sub: Infinity BassLink
XM Radio: Delphi SkyFi2 connected through AUX input
