I have tested this only on a '98 Ford F-150 and my '00 Explorer, and it has worked both times.
There is a factory "self-test" for the radio that starts by having the radio on, and having it on FM (Do not have it on CD, it will not work). Once you have it on FM, push and hold #3 and #6 buttons and the radio will run a self test at which it'll send the sound to the RF, LF, LR, RR speaker while displaying which speaker it is at on the display.
So why is this useful? Say you have no sound in one speaker - now all you have to do is test for current/voltage down there when it goes into self test mode and if you get voltage, your speaker is bad. Otherwise you have either a wire issue or a head unit issue. But if you have a good ground and you aren't getting power/current, then you should trace the power wire to the head unit (if you can). Hope this helps someone out.
The only thing I ask from you is that you try on your Explorer and then post back on here your year, model, and possibly radio choice (premium or not). Thanks
