The 4 corners have 2 possible sets. 1 set should be the colors behind the radio.

So i removed the stereo and the speaker wire colors don't match with the wire colors on the wire harness on the back of the stereo.. it's not a bose model so it shouldn't have an amp.. Not sure what to do..

This is a picture of a metra 70 7552 harness. Nissan 07 and up. No idea if they changed it in 2018. This harness plugs into the factory harness and is used to change the radio to aftermarket. Yellow wire is constant 12 volts. Find constant so you know the orientation of other wires compared to it. Your plug probably does not have a wire where the black wire is on this harness. If you do not have a meter, you should be able to use this info to figure it out.
