How to power down or reset a dodge radio/CD changer, CD is stuck?

I have a 2004 Dodge Stratus with radio/4 disc CD changer. I have 3 CD's in the player that won't come eject. I tried to disconnect the battery termial to power down the radio, but it didn't do it. Any idea's on how to power the radio down or getting the CD's out?|||maybe locate the fuse and pull it out
