    I just put in an Alpine CDA 7873 in my CX ... all is good but when I turn off the unit it makes my sub make a boom sound for about half a sec ...

    Is this normal?
    Is it just discarging power or what is this thing doing...
    It doesn't seem to be loud or long enough to cause any harm but if it is not supposed to happen it can't be a good sign....

    Also to make the deck tilt or eject a cd i need to "help" it a little on the right side anyone know how to "unstick" it...
    It gets stuck right before it first moves or when closing the unit right before it gets back to the original position.... and just on the right side.... any suggestions...
