I've got to give you some kind of prize for coming up with a tough one! Correct adapters or not, I'd take them out, put the stock radio back, and see what happens. As long as you didn't work on or unplug something else. Also, you could measure the drain on the battery with a multi-tester, and a cable disconnected.does the clock work?

The clock does not work that's the reason for the replacement of my radio but I think it was my anti- theft system and it thinks so moment stole my radio so it will drain the battery. So the next day I took the battery out then un plug and put in my new radio and my problem was solved. Thank you for the great response
