The biggest problem (as I see it) is that the amp is bypassed and the door woofers are just hooked up with the dash ones. Tis turns what are supposed to be amplified woofers into just plain speakers which are sharing signal with the dash ones.
Easy to check. If you have the jumper connector at the amp in the trunk then your door speakers are weaksauce.

Why not try removing the bypass plug and reinserting the plug back into the amp and reinstalling the fuse for the amp. There is still signal on the input wires since the signal is tapped into the car side of the harness behind the head unit, right? It can't hurt to try.
