cabin speaker help

ok while surfing my cousin was driving while i was in the water and he took a big roller over the bow turning into the big surf wake instead going the other way. i didn't see how much water came in really but he said he heard a pop then the cabin speakers stopped working. any help where to start looking for my issue?

check the amp that powers the cabins and see if it shorted out somehow or popped the fuse either on the amp on inline between the amp and battery.

problem is fixed thanks guys it was a thermal breaker was tripped just took me a while to find what it was
