Key Features

Class-D Amplification Technology: Provides high power output with efficiency, minimizing heat generation.
Digital Sound Processing (DSP): Features 4.1-channel time alignment for precise sound staging.
Customized Sound with App Control: Adjust audio settings, including EQ and crossovers, directly from your smartphone via a dedicated app.
Low and High Pass Filters: Integrated filters for accurate sound reproduction and speaker protection.
Bluetooth Connectivity: Enables wireless audio streaming and app control.

Setup and Installation

Proper installation is crucial for optimal performance and safety. If you are unsure about any steps, consult a professional installer.

1. Mounting the Amplifier

Select a mounting location that provides adequate ventilation and protection from moisture and direct sunlight. Ensure sufficient airflow around the amplifier to prevent overheating. The compact size of the XM-GS6DSP allows for flexible placement, but avoid enclosed spaces without ventilation.

2. Power Connections

Power (BATT+): Connect a heavy-gauge power cable directly from the vehicle's positive battery terminal. Install an appropriate fuse (not included) within 18 inches (45 cm) of the battery.
Ground (GND): Connect a heavy-gauge ground cable from the amplifier to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
Remote (REM): Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal. This wire signals the amplifier to turn on and off with your vehicle's audio system. Note: If using high-level inputs with a subwoofer, the remote wire is necessary to power the subwoofer stage, even if the amplifier auto-senses startup for other channels. Failure to connect the remote wire in this configuration may cause the amplifier to enter protect mode.

3. Audio Input Connections

The XM-GS6DSP supports both low-level (RCA) and high-level (speaker wire) inputs.

Low-Level Inputs: Use RCA cables to connect the amplifier to your head unit's RCA pre-outs.
High-Level Inputs: If your head unit does not have RCA outputs, connect the speaker wires from your head unit directly to the amplifier's high-level input terminals. The amplifier can auto-sense the audio signal to turn on when using high-level inputs, but as noted above, the remote wire is still critical for subwoofer operation.

4. Speaker Output Connections

Connect your speakers to the appropriate output terminals on the amplifier. Ensure correct polarity (+ to + and - to -) for all speakers. The XM-GS6DSP supports various configurations, including 6-channel, 5-channel (with bridged subwoofer), and 4-channel setups.

Front/Rear Channels: Connect your full-range speakers.
Subwoofer Channel: Connect your subwoofer. The amplifier can deliver 600W (2Ω bridged) for subwoofer power.

Operating the Amplifier

1. Initial Power On and Configuration

Once all connections are secure, turn on your vehicle's ignition and head unit. The amplifier should power on. For initial setup and advanced sound customization, you will need to use the Sony Music Center app.

2. Bluetooth Pairing

Ensure Bluetooth is enabled on your smartphone.
Open the Sony Music Center app.
Follow the in-app instructions to search for and pair with the XM-GS6DSP. The amplifier will appear as a discoverable Bluetooth device.
Once paired, you can stream audio wirelessly from your device to the amplifier.

Note: Each new device connecting to the amplifier via Bluetooth for the first time may require the Sony Music Center app to establish the connection.

3. Using the Sony Music Center App

The Sony Music Center app provides comprehensive control over the amplifier's DSP functions:

Equalizer (EQ): Adjust frequency response to tailor the sound to your preferences and vehicle acoustics.
Crossovers: Set high-pass and low-pass filter frequencies for individual channels to optimize speaker performance and protect them from damaging frequencies.
Time Alignment: Adjust the delay for each speaker to ensure sound from all speakers reaches the listener at the same time, creating a precise sound stage. (Note: Time alignment is typically set in centimeters within the app.)
Level Control: Independently adjust the output level for different channels.
Fader/Balance: Control the front-to-rear and left-to-right sound distribution.
Audio Streaming: Seamlessly stream music from various applications on your smartphone (e.g., iTunes, YouTube Music).

Maintenance

Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
Ventilation: Ensure that the amplifier's heat sinks and ventilation openings remain clear of obstructions to prevent overheating.
Connections: Regularly check all power, ground, and audio connections to ensure they are secure and free from corrosion.

Troubleshooting

If you encounter issues with your XM-GS6DSP amplifier, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Amplifier does not turn on.	No power to BATT+ terminal. Poor ground connection. Remote wire not connected or not receiving signal. Blown fuse.	Check power cable connection and battery voltage. Ensure ground cable is securely connected to a clean metal surface. Verify remote wire connection and signal from head unit. Check and replace fuse if necessary.
Amplifier goes into protect mode.	Overheating. Speaker impedance too low. Short circuit in speaker wiring. Remote wire not connected when using subwoofer with high-level inputs.	Ensure adequate ventilation around the amplifier. Verify speaker impedance matches amplifier specifications. Inspect speaker wiring for shorts. Connect the remote wire from the head unit to the amplifier's REM terminal.
No sound or distorted sound.	Incorrect input/output connections. Gain settings too high/low. Crossover settings incorrect. Damaged speakers or wiring.	Check all audio input and speaker output connections. Adjust gain settings appropriately. Review and adjust crossover settings in the Sony Music Center app. Inspect speakers and wiring for damage.
Bluetooth connection issues.	Device not paired. App not used for initial connection (for new devices). Interference.	Ensure proper pairing process via Sony Music Center app. Use the Sony Music Center app for first-time connections with new devices. Move away from other Bluetooth devices or sources of interference.
Engine RPM feedback (whining noise).	Ground loop interference. Poor power/ground connections.	Ensure all components are properly grounded to a single point. Check power and ground connections for tightness and corrosion. Consider installing a ground loop isolator if the issue persists.
