Good news: It looks like the RCAs are the culprit. Took a while to troubleshoot it, but I was methodical. I just find it odd that the Kicker XI's are the ones to blame. I probably should have just re-run the cable, but I inspected it a good distance on each end and they appeared to be fine and undamaged, nor grounded to anything. I didn't feel like cutting the zip ties and removing all the door jam shrouds and whatnot.
I checked the headunit to make sure that the outputs were fine. All 6 channels appear to be problem free. Didn't have any slack to move the other 2 channels to see if the inputs on the amp are toast, though. I'm optimistic that the amp is functional, since it's out of protect mode without the RCAs.
Hopefully a new cable gets me back in business.
*edit: Good call on giving the wiring a more thorough inspection, thanks guys!
