Help 2024 255XE Wet sounds amp problem

[tenl_710]

I have 2024 255XE，When the zone control and right volume is turned up to 100% ,Two speaker on the bow will loss of sound, When I thought it was a speaker problem, I switched the two bow speakers to the center of the boat, and now it's four speakers loss of sound. The rest of the speakers and subwoofer are fine.
And the amp is red light，I remember the normal blue light.

When the zone control and volume 100% will loss sound
When the zone control 100% volume 95% no loss of sound.
When the zone control 95% volume 100% no loss of sound.
Already replaced a 6-channel amplifier,and it's still the same.

Could it be the amp is in protect mode at 100% volume? That's weird.

It's always a red light, whether the volume is at 100% or not

Do you have access to a multi-meter? I would check for voltage first - this sounds like the issue. If voltage is staying above 12v under load then I would check resistance at each speaker wire.
