Have recently noticed that the left front speaker in my 2001 TJ simply isn't working. Not with any type of input, nor with any manual biasing (i.e. via the F-R/L-R selector joystick on the head unit).
I've got a stock OEM CD player radio unit, and can certainly begin troubleshooting at the speaker, but I'm simply curious if such failures are at all common, and if so, is the trend that the speakers tend to blow, or is it more likely that a lack of signal (channel failure) is to blame?
I'm all for upgrading the speakers at some point, anyway, but I don't want to start there if the head unit is likely at fault. Won't have time to troubleshoot this over the weekend, so I'm just throwing this out there to see if perhaps this is one of those "oh, yeah -- that happens to TJ's all of the time" sort of things. Do these dash speakers go out from time to time? I did check the wiring during a quick check this afternoon, and the connector plug IS intact.
