Back Speakers

[TrippleXCA]

I just got the car, The only 2 speakers that seem to be working are the 2 front door speakers.
The speakers in the rear doors are there. But nothing coming out of them.
I have checked the fade on the factory deck. When I put it to the rears, I don't hear anything.

Any Ides?

They're blown or the wiring is faulty.
