  • Key Specs
    • Continuous Watts x Channel @ Ohms: 45 W x 4 x 4 Ohms
    • Maximum Watts x Channel @ Ohms: 100 W x 4 (This is the maximum load the speaker, subwoofer or amp can drive.)
    • Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
    • Number Of Channels: 4
    • Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
    • Bridgeable: false (Bridging an amplifier increases the power it supplies to the speaker(s).)
    • Low-Pass Crossover: Fixed (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • High-Pass Crossover: Fixed (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

  • Audio
    • Number Of Channels: 4
    • Minimum Frequency Response: 20 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Maximum Frequency Response: 20 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Total Harmonic Distortion: 0.08 percent (Measurement of the harmonic sound distortion. The lower the percentage, the cleaner the sound.)
    • Signal-to-Noise Ratio (SNR): 100 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
    • Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
  • Features
    • Bridgeable: false (Bridging an amplifier increases the power it supplies to the speaker(s).)
    • Low-Pass Crossover: Fixed (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system.

Power up your in-car sound with the XM-S400D stereo amplifier. Each of the amplifier's channels delivers high dynamic audio, while low and high pass filters separate the frequency range to ensure a more accurate sound stage. The speaker-level input makes installation easy, even with integrated head units.

  • 180W total power: RMS rating of 45W x 4 @ 4 ohms, at 1 kHz, 4 channels driven for robust audio.
  • High-pass and low-pass crossovers: Ensures flexible operation.
  • 4 ohms impedance: Conducts power evenly to keep the speaker at an appropriate level.
  • 0.08% THD (Total Harmonic Distortion): Provides clean sound.
  • 100dB signal-to-noise ratio: Offers crisp audio.
  • Bass boost: Delivers pounding audio.
  • MOSFET power supply: Delivers efficient performance.
  • 4-channel output: Allows easy system expansion.

Product Manuals

Q: Does this amp need a wiring kit? Direct hookup to the battery or can it be powered off fuse box?

A: Hi Chris, please refer to pg.6 of the link below for more information about the power connections. I hope it helps. Thanks! ^Ron https://docs.sony.com/release//Manual_4581373112.pdf

Q: Product states built in crossovers but does not specify what they are set at for high and low. Do we know what they are or is there someplace we can find out this info?

A: Hi BrianK, Both Low-Pass Crossover and High-Pass Crossover are FIXED in this car stereo. Thanks, >Joffrey
