I replacedi the stock stereo with a nice Touchscreen head unit & wired it all up myself correctly & carefully
I noticed some month's later on Driver sidei only have a tweeter going. Still sounds good all round, but way better when randomly once a blue moon i hear the drivers door speaker going again. On mine something must be up with i think maybe stock wiring that goes to the dooe somewhere behind the steering wheel..
I know that the random times it came back on it was during turning the wheel, and would later go out again same day or drive.
Wire might be a bit caught up, or a bad earth to that speaker
