I am trying to figure out why I am getting no sound from the passenger side of my 1998 e36 m3. Every speaker works except for the passenger side mid range and tweeter. I have already tried swapping the speakers, swapping the head unit, swapping the amp. So far everything left me with the same issue..... This leads me to believe something is messed up in the wiring between the amp and the speakers? any ideas?

I'm assuming that you've swapped to known working parts, so I would make sure you have continuity at multiple places along the wiring, specifically for the passenger side. Check the connector on the head unit, the wiring for the amp, and make sure your getting a ground. For me, swapping the head unit with a good aftermarket solved my problems, others it was the amp, haven't seen many wiring problems but I would suspect a ground first.
Swapped headunit, amp, and speakers... Still no passenger front sound. All the wires look good so I am at a complete loss. Anyone have any advice?
Do you have a volt/ohm meter? Check for continuity in the wiring and that will tell you if you have a broken wire somewhere and you can then trace it. you might want to pull back the sheath on the door jamb and look for broken wires.
