Default JL amp flickering light

My JL 800/8 amp's power indicator light flickers on and off. Is there a problem with this? Low voltage maybe?

The green light will flash during the muted power up process which is a short sequence. Is there any other behavior that coincides with the flashing LED?
Low voltage is always a concern.

No behavior, just the light. There is no pattern to the flickering either. Sometimes steady on, sometimes flickers. I would definitely not call it flashing like it is a signal for something.

Red would indicate thermal.
Flashing green might indicate to me that the amplifier is re-initiating turn-on because of low voltage, possibly as the voltage momentarily sags. But if you hear no behavior change then it becomes a question.
Check the voltage specifically across the amplifier primary power terminals as the light is flashing. Same with the turn-on lead.
Check in with JL Audio technical tomorrow. Contact your dealer for assistance. If it's not affecting the performance in any way, then get the issue on record so that it will still be warrantable (if your warranty period is approaching) after the boating season is over.
