About the Sony XM-SD61X

Sony's Xplod Specialty Series amps keep the sound strong — all day long! MOSFET power supplies and output stages ensure you'll have a steady stream of power, even when the amp is subjected to high demand. Xplod amps are CEA-2006 compliant so you know the power ratings are a true measure of the amp's performance!

Want big bass? Look at our Subwoofers Sony's Xplod Specialty Series amps keep the sound strong — all day long! MOSFET power supplies and output stages ensure you'll have a steady stream of power, even when the amp is subjected to high demand. Xplod amps are CEA-2006 compliant so you know the power ratings are a true measure of the amp's performance!

The XM-SD61X subwoofer amplifier puts 300 watts RMS power at your disposal, plenty of power for a subwoofer. Got two subs? This brawny beast will produce a massive 600 watts to a 2-ohm load. The bass boost (0-10 dB at 40 Hz) kicks up the lows when it's needed. A handy remote level control allows you to adjust the amp's output level right from the driver's seat.

A subsonic filter removes super-low bass frequencies that can detract from system performance. The speaker-level inputs allow for easy integration with any system (even a factory radio), while the preamp outputs simplify hooking up an additional amp. The cool gray finish and blue lighting look great, and all four Specialty Series amps (XM-SD22X, XM-SD46X, XM-SD51X, and XM-SD61X) have exactly the same footprint — a nice touch if you're planning a multi-amp installation!

Features

Class D Amplifier: The XM-SD61X amplifier is a Class D mono amp. Class D technology is a method to convert and amplify music signals with MOSFETs to high-speed pulse signals. Class D amps feature high efficiency and low heat generation.

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

  • 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 a DC current is generated

LED: The amplifier has an line of four LEDs on the top panel that glow blue when the amp is on. There is also an LED that lights in red when the protection circuit is activated.

Low-pass Filter: The XM-SD61X is equipped with a low-pass filter, continuously variable from 50-300 Hz, with a slope of 12 dB/octave. It is constantly activate (cannot be switched off).

Bass Boost: For added low frequency performance, this amplifier has a bass boost centered at 40 Hz, variable from 0 to 10 dB.

Terminal Cover: The XM-SD61X comes with a protective cap that fits over the power wire terminal strip to help prevent accidental short circuiting.

Remote Level Control: A level control is included that can be mounted in the front of the vehicle for easy access. The remote is connected to the amp with the included cable (4 lead phone cable with RJ-11 connectors at both ends). The width of the remote is 2.087", height is 1.187", and depth is 2.196". Mounting hardware is included.

Inputs and Outputs Notes

Speaker Outputs: Although this is a mono amplifier, there are screw terminals for two speakers (each terminal is 0.35" wide). They are not stereo outputs, but summed (L+R) mono, and internally wired in parallel. If you connect two 4-ohm speakers to the amp, the amplifier will see a 2-ohm load.

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

Remote Terminal: The remote turn on screw terminal is 0.35" wide.

Speaker-level Input Harness: The amp comes with a speaker-level input harness with a 4-pin Molex plug. This allows you to easily connect the amplifier to a factory radio or a receiver without preamp outputs.

Preamp Output: This amplifier includes a stereo preamp output, which allows you to send an unfiltered signal to another amplifier. Note that you must be using the line level input, not the speaker-level input, in order to use the preamp output jacks.

Specifications

CEA-2006 Compliance: The specifications given by Sony for the XM-SD61X amplifier comply with the new CEA-2006 Amplifier Power Standard from the CEA (Consumer Electronics Association). All manufacturers who comply with the standard can display the CEA-2006 logo on their product.

RMS Power Rating (measured at 14.4V): 300 watts x 1 into a 4-ohm load with an input voltage of 14.4 volts

Signal to Noise Ratio: 76 dBA (1 watt into 4 ohm load)

Note: Minimum impedance is 2 Ohms.

Wiring Note

Current Drain: The XM-SD61X has three 30 amp fuses for a total of 90 amps, the 4 gauge amp wiring kits we list as accessories have 80 amp AGU fuses (typically). The amp's specs list 75 amp current drain at rated output so the peak current is likely to spike higher than 80 amps. To get the maximum output from the amp, an ANL hi-amp fuse and ANL fuse holder are needed. Our 2 gauge and bigger wiring kits have ANL fuse holders and fuses bigger than 90 amps.
