No audio from main speakers

So over the years the main speakers in the doors have quit working. The front door tweeters still work and the right front goes in and out. Is this a speaker issue or a head unit issue. Just wondering if anyone here has seen this before
Thanks

 

If the Tweeters still work but the mains don't then it's either bad speakers, bad tweeters, or a broken wire in the door because the main speaker circuits go through the Tweeters.

 

I tried taking the tweeter wires and plugged them into the main and nothing. So I think I'll order a set of speakers tomorrow and see what happens.
Thanks

 

My passenger side door speaker stopped working. I removed the door panel, unplugged the speaker cable from the speaker, then temporarily connected an old speaker I had laying around. This speaker worked, therefore the problem was a failing (factory) speaker.

Crutchfield is a great source of speakers and other audio/video needs.

 

Thanks for this diagnostic tip. Both my woofers had failed in my '13 (not at once) which I thought was odd and made me suspicious of the head unit. But the tweeters worked. Ordered up some new speakers and wa-la, sound is back.

And much better I might add. Those OE woofers are lame!
