sub stopped working

Yesterday I was cleaning out my truck and I decided to put my shorter rca cable back on. to do so I unplugged my deck, and so on. when I put the deck back in set it back to the normal settings I had it and the sub was not working. does anyone have an idea of what is going on. i tried putting back on nothing. the amp is getting power, and i am lost for ideas

you DID connect the rca to the back of the deck in the right spot right?
