More Headunit headaches

[EZ56]

I got my headunit all hooked up, all wires connected correctly, but both my right front and right rear speakers aren't working. They worked fine when the stocker was in there. I'm clueless, because i didn't touch anything else, anyone else experience this? I'm thinkin maybe it's a bad harness?

The pins in the (car's, I think) harness can pull out. Check that all the connectors are good. The wires are labeled, so you know which ones to look at.

I double checked all connections and made sure they were snug, and have the same result. There is one plug that connected to the back of the stock unit that has no place on the new one. It's a small black square plug, but i don't see how that could affect it if the left speakers work.

check with metra they have the harness that plugs into the car harness and splices into the radio. it would plug into your black connector that is not connected to anything. i think that is your issue.

Just for a reference here is the black thing I'm talkin about:

I messed around with the wires while the HU was on and got yet another odd result. When I disconnected and touched the wires for the right front, right rear, left front, and left rear to their correct wires they all affected the left speakers with no response from the right. When messing with the right front/rear I noticed that when the wires touched the left speakers would get louder and vice versa, they would get lower when disconnected. I've never seen this before.....
