Radio turn off n On by itself

[kakarot]

Really need help to solved this radio issue that I'm experiencing, the problem is the radio will loop off then on off then on for maybe 5 to 10 min max for it to function as normal. I have already replaced the radio with a new one and it still doing the same thing. This is going to be my 3rd radio that I'm replacing to see if it still doing the same thing off on off on.

I notice that when it flicker(turn off turn on) for 5 to 10 min it only happen in cold weather and in the morning hr the most. On a sunny day the radio will function as normal. Do I have a short somewhere on the electrical please pinpoint me to the right direction so I can try to diagnostic this issue.
Thanks!

sounds like its a short in the power wire. not sure as to why it only happens in cold weather but heres a way to troubleshoot it. disassemble the dash and pull your radio out but do not disconnect it. next turn your cars power on and individually pull each of the wires that is connected to your radio. DONT yank them out just give them a little tug and see if that turns off your radio. i had this problem with my door speakers, they would randomly shut off and i didnt know why. turns out when i had them replaces the guy didnt seal the wires very tight and the wire would touch metal when it would move and cause power not to go to the speaker. i have an aftermarket deck that i installed myself a while ago and if i remember correctly the power should be a blue wire. hope this helps.
