Alpine CDA-9830 off-n-on mode

check all the power connections it could be that the remote wire is hooked up to somthing falty, try hooking it up with the positive power to see if that fixes the problem, useing this method will require you to have to turn off your stereo manually. the power wire is yellow and is usually thicker and the remote or (ignition) wire is red, just wire them both together. the remote wire is usually connected to the positive end of somthing that turns on when the ignition is on like the cigarette lighter. if thats not the problem it could be that its not getting enough power ether because the power wires going to it are to thin or there isn't a good connection. check the voltage at your battery and at your stereo.
