Installed new dash speakers now I don’t hear any audio from the door speakers.

I replaced my two front dash speakers in a 2017 forester but now I don’t hear any noise from the rear speakers. When the two new front speakers are plugged in I don’t hear any sound from the door speakers. This is even with me messing with the fade. My other speakers start working fine when I unplug the dash speakers though. Anyone have any ideas. I’m using an aftermarket head unit.

I believe the dash speakers are wired into the head unit with the same AV plug for each door speaker side. If this is the case then could this bea problem of impedance? The new dash speakers have 5 ohms while the old ones had 3.
