Which dummy resistors do I need?

Could be a loose speaker thats shorting against the door then.

I guess my question would be why do they work (when they do work!) until I turn the car off, then not again when I turn it back on? (at least for a few days or weeks, when they sometimes magically reappear)

Closing the door makes the loose wire contact the metal and maybe its sitting on something, or sticks to the door till you close it a few times and then allows the amp to return to normal operations.

Fair points!

Would a short in one of them cause all four to stop working but allow the head unit and subwoofer to continue working fine?

As getting the door off will be a big job for someone inexperienced, what should I be looking out for if accomplished?

Yea, cause the HU and sub work independently of the internal speaker amp. If you can pull the panels off, look for any hacked wiring, should be easy to spot. From what i understand, the Focals should be plug n play with the stock wiring, but that doesnt mean someone didnt hack it up. They have made aftermarket to stock adapters for decades and people still hack them off when installing a radio these days.
