Overview

Our take on the Sony XM-754SX

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.

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.

Details:
  • 200 watts x 2 in bridged mode
  • 100 watts x 4 into 2 ohms
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • MOSFET power supply and output stage
  • front and rear high-pass/low-pass filters variable from 50-300 Hz, 12 dB per octave
  • adjustable bass boost (0-10 dB at 40 Hz)
  • line-level and speaker-level inputs
  • frequency response 20-20,000 Hz
  • signal-to-noise ratio 100 dB
  • dimensions:14"W x 2"H x 10-1/2"D
  • 1-year warranty

Features

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

Specifications

Specifications:

  • 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

Controls:

  • 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

Indicators:

  • 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

Inputs/Outputs

Inputs

  • +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)

Outputs

  • Speaker outputs: screw terminals (0.35" wide)
