hey everyone ive looked at plenty threads containing wiring and speaker hook up i just want to see if someone can help me much appreciated

the problem is that i hooked up a aftermarket headunit single din i bought the harness that is needed so i wouldnt have to cut the stock harness and the amplifier harness as well. now only the driver speaker and rear passenger speaker works. the passenger front and driver rear doesnt work :/

 

How did you did your wiring? Followed metra's diagram for the harnesses?

 

yes i did
