JBL amp repair?

Hello hopefully someone can help me out. So recently I upgraded my front door speakers as they were blown. I replaced them with 2 ohm speakers but now the audio cuts out when the volume is high and no audio is coming from my right speaker (door only) i tested the speaker wires and it’s good. I ended up taking the amp apart and started ringing things out with a multimeter and sure enough where the (right door speaker plugs into the harness/into amp it shows that both connections are grounded. I’ve attached some photos so hopefully that helps . Worse case scenario I’ll just bypass the amp but figured it’s worth attempting to repair or just learn something.
