Deck won't power on. Any suggestions?

So I went to plug my antenna into my newer deck, I didn't bother to when I first got it. I wired what I thought was the antenna, and it turned out I was wrong. So I corrected my mistake, plugged in the right stuff to the back of my deck (Kenwood, if that matters) and got everything back in the right place. I turn the car on and my deck won't even power up. Any suggestions? I drive a 98 Altima gxe if that even matters. Thanks for the help!
