Answer :

answer:I can offer two possibilities. 1) The power connection is incorrect . In general after market radios get their power from two places in the fuse box: 12V (or BATT) , and ACC (or IGN), The 12V lead is supposed to be on all the time. That is what keeps your radio’s memory alive. I’m guessing either the 12V connection is disconnected or connected to IGN. 2) If the radio is connected properly, the next thing to check is the voltage at the 12V lead when you are cranking. It is possible your battery is getting weak and is drawing the 12V line down below the threshold needed for the radio. Use a Volt meter to verify the voltage stays above 10V when you are cranking .
