If not, it's possibly busted.
I lived out in Cross Creek when i first moved to FL 4 years ago, nice area!
so i tried what you said and got no sound from anything so i am thinking that the head unit is done. but im still wondering what is causing the issue if it isnt that wire from the amp to the sub then what? im stumped
