Speaker issues

[Elkinsa]

Okay so I got a ‘13 vlx this summer. Lots of fun with it. Love the boat. All speakers worked great when I first got it and over the summer a few of them have stopped working. The sub for one does not work. I have checked to make sure the amp is working and it’s is. Blue light is on. I have made sure the sub is turned on as well on the audio control. Basically the left bow speakers, left walkthrough speaker, right tower speakers, and left speaker on the back bench do night work. I have messed with the left and right settings. All amps have the blue light on as well.  I thought I would put it out to the crew but if I can’t get it working I will just have the dealership do it. 

Boat is currently up at cabin  so not close to check on a few things  

 

Any help is appreciated. 

Thanks!

With as many issues as you are describing, I would check the back of the amp board for poor connections first.

Balance setting?  Sounds like the balance is all the right, but the right and left tower chnls are reversed. BB could have just dropped the left side output.
