Sony delivers the sound

Bored with your vehicle's sound system? Sony's XM-N1004 4-channel amplifier will add clarity and power to your system, delivering 70 watts RMS to each of your speakers, so you'll have more fun listening to music on the road. To add some low-frequency fun, you can bridge the MX-N1004 amp into 2-channel mode and drive a couple of subwoofers with 175 watts each.

High- and low-pass filters help all your speakers sound their best. Sony placed all of the MX-N1004's connections and controls on the front of the amp, for a cleaner installation with easier access to adjustments. To protect the amp from overheating and shutting down, an Auto Thermal Control lowers the power output slightly during those moments of extreme, hard driving play. Sony shows its commitment to high quality by gold-plating this amp's connectors for reliable conductivity.

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.

Crutchfield Customer Review (What's this?)

Purchased this amplifier to go with the Sony WX-GT90BT head unit along with 4 new speakers for my Ford F-350 Crew Cab. Excellent product and the installation was trouble free.

Pros: Great sound, more power than I need but that is exactly what I was looking for, unit is constructed very well, solid.

Cons: None.

Product Research


CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow consumers to compare amplifiers on an equal basis. Using CEA-2006 criteria, the Sony XM-N1004 is rated at 70 watts RMS x 4 channels, with a 93 dBA signal to noise ratio.

Pulse Power Supply: The amplifier utilizes a Pulse Power Supply system to regulate the fluctuating voltage received from the car's electrical system.

Crossover: The front and rear amps have independent crossovers:

  • Front: a three position switch sets crossover to low pass, off (full range), or high pass; the crossover point is fixed at 80 Hz and the slope is 18 dB/octave when set to low pass, 12 dB/octave when set to high pass
  • Rear: a two position switch turns the low pass filter (LPF) on/off; the crossover point is fixed at 80 Hz and the slope is 18 dB/octave

Power Connections: The power, ground, and remote turn-on screw terminals are 0.35" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals. A protective cover is included for the power/ground/remote terminal block.

Speaker Connections: The speaker screw terminals are 0.35" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals.

RCA Input: The amplifier has two pair of stereo RCA line level inputs (front left/right and rear left/right).

Fuse: The amp is protected by two 25-amp ATO blade fuses.
