dead pair of ex602a's

i have 4 speakers in my truck (well 6 if you include the two front tweeters). the back two are ex602a's. recently i noticed there was no audio coming from either back speaker. a little trouble shooting revealed that both are somehow dead now. to verify i put an old car speaker i had laying in the garage and connected the speaker wire in the back doors to it and the audio was fine.
the exact detail of the dead speakers is this: you hear a very faint thin audio track from each speaker but only at extremely high volume, other than that, nothing comes out of the speaker. i should also note the physical appearance of the speakers is perfect. there is no indication of a blown woofer cone or surround, no tears, etc.
1) how could both speakers die in this manner at the exact same time? they have been in the truck for roughly 5-6 years.
2) is there a crossover inside the ex602a that isn't visible? since there's basically no audio coming from either speaker i assume this crossover inside each speaker is blown, true?
3) is such a thing fixable? i'm not even sure how to disassemble this speaker to get at any such crossover.
anyway, any ideas?

i have taken one of the speakers out of the truck. i connected it to my home audio system. the thin audio i hear is coming from the tweeter. there are speaker leads that go through the woofer and to the tweeter. if i connect my speaker line directly to the tweeter, i can hear that thin sounding audio. nothing i can do can get any audio output from the woofer.

so in researching on the internet, it appears that there must be a passive crossover in this speaker, with a low pass filter and a high pass filter. so i assume that a resistor or capacitor blew.
however, i still don't know how to "see" these components, ie, where they are located within the speaker and how to get at them.
anyone know how to dissassemble this speaker or have schematics to it? -

you know this actually applies to all car two-way and three-way speakers that do not have an external crossover module. where do they hide the internal one???

I've got an extra pair of EX 602's laying around (actually 2 pairs). You want to replace instead of repair?

no i actually already bought a new pair. i just got curious about how they make these type of speakers and how to repair them.
