Front speaker blown, or more likely a stereo channel failure?

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.

I've seen and had plenty of speakers fail. One time, my fader control stopped working and I couldn't adjust the fade anymore. I've never had a single channel failure before.

Not to say it's beyond the realm...

If the speaker doesn't work at all, it's just as likely to be wiring as a bad speaker. So, check that first. They are very easy to remove, so if the bad one is wired ok (you can't find any shorts) the pull the opposite and put it in the bad one's spot and check it. At least you'll know what it's not.

Good luck.

Thanks, Larry. That was the plan -- just haven't had a chance to get quite that far yet.

I just upgraded all of the stock junk to alpine stuff and it made a
huge improvement. I did 6.5 in the stock roll bar where a 6 is supposed
to go and I did 5.25 in the dash where the 4x6??? Are supposed to
go. Also did an alpine headunit and a 400w alpine amp for the speakers. No sub yet and I honestly don't know if I will ever put one in because the properly powered alpine type-r speakers make very good bass by themselves. If your upgrading I highly recomend alpine but you really need to amp their type-r, use the type-s I'd you don't plan to run an amp. The stock headunit doesn't really like running even the type-s tho.
