I have a 2006 Ford Fusion and had a new stereo installed but now my 6x9 rear speakers aren’t working. They are getting power and I’ve replaced all the fuses for the amplifier. The speakers are in excellent condition

Define "they are getting power".  speakers work when power is applied. are they powered by an aftermarket amplifier or the head unit?

If the new stereo was connected to the amp with RCA, what output did they use?  If they used the sub output, it may have a low pass filter or may be turned off.
