Sony's Xplod XM-754SX 4-channel amplifier packs aggressive styling and powerful performance into one sweet-looking package. A lightning-fast MOSFET power supply and high-current output stages mean this amp will get tough when the going gets rough.

You'll also get a front and rear high-pass/low-pass crossovers (variable from 50-300 Hz), speaker-level inputs, and adjustable bass boost (0-10 dB at 40 Hz). All wiring terminals are recessed under the edge of the heat sink for a neater installation.

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.

Controls and Indicators



Pulse Power Supply: The pulse power supply regulates fluctuating voltage from the car's battery to keep the output power of the amplifier from fluctuating with the input voltage; this results in consistent power delivery despite input voltage fluctuations.

Crossover: There are separate crossovers for the front and rear channels. Each crossover is variable from 50-300 Hz, and can be set for high-pass or low-pass operation. If you need full range output, the crossover(s) may be turned off. The crossovers have a slope of 12dB/octave.

Bass Boost: Bass response may be boosted from 0 to +10dB for frequencies around 40 Hz; there are separate low boost level controls for the front and rear channels).

Test-tone: The amplifier includes a built-in oscillator that can be activated to check system performance; if the test-tone button is pressed and tones are heard through your speakers, the amplifier is in good working condition.

Protection circuitry:

  • Over current: shuts off the amp when the input signal is too high
  • Offset: shuts off the amp when the output voltage is too high
  • Thermal: shuts off the amp when the operating temperature is too high



  • Rated power output at 2 ohms: 100 W x 4 (20-20kHz, 0.1% THD)
  • Max power output at 4 ohms: 170 W x 4
  • Max power output at 4 ohms, bridged: 400 W x 2
  • Operating voltage: 10.5-16V allowable
  • Current consumption: 40 A

Controls and Indicators


  • Crossover switches: one switch for the front channels and another switch for the rear channels; may be set to "HPF" (high-pass), "LPF" (low-pass) or OFF
  • Crossover frequency controls: one control for the front channels and another for the rear channels; inset rotary controls that set the crossover cut off frequency from 50 to 300Hz when the low or high pass filter is engaged
  • Low Boost controls: one control for the front channels and another for the rear channels; inset rotary controls used to set the bass boost from 0 to +10dB at 40 Hz
  • Level controls: one control for the front channels and another for the rear channels; inset rotary controls used to set the amplifier's input sensitivity to match the level of the incoming signal
  • Test Tone button: allows for system condition check; if tones are heard when the button is pressed,  the system is in good condition


  • Over Current LED: illuminates in red when receiving a powerful signal
  • Offset LED: illuminates in red when the voltage going out to the speaker terminal or the pin jack is too high
  • Thermal LED: illuminates in red when the temperature rises to an unsafe level
  • Power LED: illuminates green when the unit is on



  • +12V (power): screw terminal (0.44" wide)
  • GND (ground): screw terminal (0.44" wide)
  • REM (remote turn-on): push-pin spring terminal
  • Speaker-level inputs: push-pin spring terminals
  • Line-In: two sets RCA stereo jacks
  • Fuse: 40 amp fuse (inserted)


  • Speaker outputs: screw terminals (0.35" wide)
