I guess I will have to troubleshoot later on tonight or tomorrow depending when I get off work, I think i'll disconnect the drivers front speaker and connect the leads to the passenger output on the HU and then connect the passengers speaker to the drivers output and see what happens.. Will report back..
They may have never messed with the factory amp/wiring. The (Blue?) antenna/trigger wire probably wasn't connected because of that.
