My passenger side door speaker and rear speaker went out. Does anyone have a clue how this happened and what to do to fix it? I have a after market head unit and a sub in the trunk... Im thinking maybe the wires for the speaker in the door came out and the rear speaker is connected to it.
P.S. the rear speaker wires are connected I checked this.

 

Sounds like the wires in the back of the head unit harness came loose if it's both speakers, they should be separately wired
