⚠️ Common Symptoms of a Failing Naim Audio Amplifier

Bentley Mulsanne owners often report the following issues with their factory amplifier:

• No audio output from speakers

• Distorted or crackling sound

• One or more channels not working

• Amplifier will not power on

• Intermittent audio dropouts

• "Naim system error" or "Amplifier fault" messages on infotainment screen

• Overheating or amplifier shutting down

• Blown fuse with no obvious cause

These issues typically point to internal failure within the amplifier’s output stage, power supply board, or communication interface.

🧠 What Fails and How We Fix It

The Bentley Naim amplifier is a high-end component featuring advanced digital signal processing (DSP), class D amplification, and vehicle-specific tuning.

Over time, several things can fail internally:

• Blown output MOSFETs or power transistors

• Failed power supply components (capacitors, regulators)

• Shorted speaker channels

• Cracked solder joints or thermal damage

• CAN-Bus communication failure

• Water intrusion or condensation-related board damage

Our repair process includes:

• Component-level diagnosis using advanced test equipment

• Replacement of OEM-grade components

• Reflow or resoldering of critical joints

• Full bench testing before return

We ensure that your amplifier is fully functional and ready for plug-and-play reinstallation — no reprogramming or coding required.
