Tower Speakers Clicking, No Sound Otherwise

[cpuwhiz22]

I didn't know if the stereo forum was a better fit for this, but since its troubleshooting related I figured I would start here.  I recently got my boat (2015 23LSV) in the water and I noticed that when I power up the stereo, there is a click sound that comes from the two port side speakers at a 3-5 second interval.  When I tried to troubleshoot, I also noticed that sound seems to be coming from all of the other speakers in the cabin, but there is no audio coming from any of the tower speakers, and the click sound is coming only out of the two port side speakers.  I have attached a picture of the boat to show the tower/speakers and the amps (though I didn't take any good pictures of the speakers themselves).  Does anyone have any idea which amp is responsible in this configuration for the tower speakers?  I am trying to see where I should start with my investigation, but it is a bit unclear as of now.  I didn't spend a ton of time on this yet, so I can gather more information next time I am out there.  Was just hoping to have something to look at/for next time I go out.

Thanks!

The large rear-most amp is for the tower speakers, the smaller center amp is for the subwoofer, and the mid-sized forward amp is for the cabin speakers.

Thanks so much!  This will at least help me focus my troubleshooting efforts!  Much appreciated!
