Sony XM-N502 Specification

The Sony XM-N502 is a versatile and robust two-channel car amplifier designed to enhance in-car audio systems. It delivers a powerful output, with a maximum power of 500 watts, ensuring dynamic sound reproduction. The amplifier operates effectively within a frequency response range of 5 Hz to 50 kHz, offering a wide spectrum of sound for a fuller audio experience. Its signal-to-noise ratio is rated at 100 dB, reducing background noise and providing clearer sound quality. The XM-N502 features a low-pass filter, which enables users to tailor the sound output to their preference, particularly enhancing the performance of subwoofers by filtering out high-frequency sounds.

The amplifier's design includes a robust chassis with a heat sink for efficient thermal management, ensuring reliable performance without overheating. It has both high-level and low-level inputs, providing flexibility in its installation across different car audio setups. The high-level input allows the amplifier to connect to factory-fitted audio systems without requiring additional adapters, while the low-level input is suited for aftermarket systems. The XM-N502 is equipped with overload and thermal protection circuits to safeguard against damage from power surges or excessive heat. This model also supports bridgeable outputs, allowing users to combine the power of both channels to drive a single, more powerful speaker or subwoofer. The Sony XM-N502 is an ideal choice for those seeking to amplify their in-car audio system with reliable performance and adaptability.

Sony XM-N502 F.A.Q.

How do I properly install the Sony XM-N502 amplifier in my car?

To install the Sony XM-N502, first disconnect the negative battery terminal to ensure safety. Mount the amplifier in a well-ventilated area. Connect the power cable from the battery to the amplifier, ensuring you use an in-line fuse. Connect the ground wire to a metal point on the car's chassis. Finally, connect the RCA cables and speaker wires to the amplifier.

What should I do if my Sony XM-N502 is overheating?

If the amplifier is overheating, ensure it is installed in a location with adequate ventilation. Check for any blockages around the air vents. Additionally, verify that the speaker impedance matches the amplifier’s specifications. Overloading the amplifier can cause overheating.

How can I troubleshoot if there's no sound from my Sony XM-N502?

If there's no sound, check that all connections are secure. Ensure the RCA cables are properly connected to the head unit and the amplifier. Verify that the amplifier's gain is set correctly, and check the speaker connections. Also, ensure the power and ground wires are securely attached.

Can I bridge the channels on the Sony XM-N502?

Yes, the Sony XM-N502 can be bridged to output more power to a single speaker or subwoofer. To bridge the amplifier, connect the positive speaker wire to the positive terminal of one channel and the negative speaker wire to the negative terminal of the other channel. Consult the manual for specific instructions.

What maintenance is required for the Sony XM-N502 amplifier?

Regularly inspect the connections to ensure they are secure and free from corrosion. Clean the exterior of the amplifier with a soft, dry cloth. Periodically check the mounting hardware to ensure the amplifier is securely fastened.

How do I adjust the gain setting on the Sony XM-N502?

To adjust the gain, turn the head unit’s volume to 75% of its maximum. Then, slowly increase the gain on the amplifier until the desired output level is reached without any distortion. It’s important to set the gain according to the input level to avoid damaging the speakers.

Why is there a buzzing noise coming from the speakers connected to my Sony XM-N502?

A buzzing noise may be due to a ground loop issue. Ensure the ground wire is securely connected to a clean, unpainted metal point on the car chassis. You can also try using a ground loop isolator on the RCA cables to eliminate the noise.

How do I protect my Sony XM-N502 from power surges?

To protect the amplifier from power surges, always use a fuse on the power cable close to the battery. This will protect against electrical surges that can damage the amplifier. Ensure the fuse is rated appropriately for the amplifier’s power draw.

What are the ideal speaker specifications for the Sony XM-N502?

The ideal speaker specifications for the Sony XM-N502 include a 4-ohm impedance and a power handling capacity that matches the amplifier’s output. This ensures optimal performance and prevents damage to both the amplifier and the speakers.

How do I reset my Sony XM-N502 amplifier?

To reset the amplifier, first turn off the car's ignition. Disconnect the power cable and wait for a few minutes. Reconnect the power cable and turn the ignition back on. This can help resolve minor issues by resetting the internal circuitry.
