What to do if my ESX SX-2000D Amplifier is in protect mode?
- J
  Jill ValenciaJul 30, 2025
  If your ESX Amplifier is in protect mode (red display), it could be due to several reasons. First, ensure that speaker cables are not shorted. Second, check for inadequate cooling and relocate the amplifier to provide better airflow if needed. Third, avoid driving high power levels into low impedances by reducing the volume or ensuring the loudspeaker impedance matches recommendations. Finally, verify that the battery voltage at the amplifier's terminals is at least 11 volts.

Why does my ESX Amplifier have a ticking or whine that changes with engine RPM?
- M
  Mark RaymondAug 8, 2025
  If you hear a ticking or whine that changes with the engine RPM in your ESX Amplifier, it could be due to RCA cables being too close to a fuel pump or distributor; try relocating the cables. Also, ensure the head unit ground is directly connected to the vehicle chassis and try supplying the head unit with a clean +12 volt supply directly from the battery +. This type of noise can be caused by some kind of instability, causing oscillations in the system.

What causes hiss or white noise in my ESX SX-2000D?
- D
  Deborah SmithAug 20, 2025
  If your ESX Amplifier is producing hiss or white noise, it could be due to overloaded speakers or a noisy head unit. To troubleshoot, unplug the amplifier input RCA cables. If the hiss level reduces, the source unit is at fault. Also check RCA cables.
