When you have time-this will be a good test
I've got an update with good news, bad news, and a little bit of funny news... Turns out through my stupidity I had the RCA cables plugged into the wrong slot the whole time After correcting that, I got power going to my rear woofers again. I now have half of my bass back, but unfortunately my front door speakers STILL don't work (it was like this still when I bought it). I'm beginning to think my amp is bad, how would I test this? I have a 12v power checker, should I touch each pin of the amp and see if it works? Or could I even hardwire these speakers somehow? Thanks in advance and here's pics to clear it up a little more.

That is good news, finding a swap like that one can be tough. Good work going back over everything.

Do you have one amp or two?

If you have two you might be able to switch them out.
The 12V tester won't be much help other that making sure it has 12 power.

I believe there are actually 3 amps, 1 hidden behind the stereo (that from what I've read is unreachable) and then two in the trunk. I will try switching them out tomorrow and seeing if I can get the front speakers working. Also I should note that when I plugged the RCA cables in their proper spot, it's the white one that isn't working if that helps at all. Thanks for the advice and I'll be testing the amps tomorrow!
