update the driver side door speaker is working great not cutting in or out at all and that was the side that never worked at all the passenger speaker always worked until now the passenger speaker dont work but while driving after a little while the speaker randomly comes on. i also just put in a new ground from the oil stick brace to the frame

 

That might Help but it sounds mostly like the speakers were the issue in general.
Perhaps you might want to upgrade both doors to a matched pair, and go from there if not solved?
