Rear speakers perform poorly

If you've tested everything, I guess it's time to check for a new HU. I've always been told that running an amp without load is bad, not sure how true that is, but I take the habit to change the fader to 100% front when there are no rear speakers.

I am pretty sure that the front tweeters are in fact wired in parallel with the speakers.
My best guess is that the HU is bad.
The funny thing with my fade settings is that even if I put it in R7 ( the maximum setting for the rear speakers) the rear speakers are still underpowered. And If I put it on R5 (so the fronts go to +2) the front speakers produce maximum power like the faded balance is at 0.
I don’t know if I explain it correctly. All I am trying to say is that even the fader has malfunction
