I recently encountered a problem with my audio system in our 2004 F150. When the radio came on, there was nothing but the sub woofer working. Nothing coming
from the door speakers. This is the original system that came with the truck. I have never altered anything on the truck. I have tested all the fuses and made sure
there was power to all the fuses. I have tried balancing speakers, moving them from side to side and front to rear. I have tried tuning out all the base and running all
treble. Nothing I have tuned matters, still just the sub woofer. I pulled the radio and checked the plugs, everything looks great. No burned looking wires or connecters.
I've searched you tube and haven't found any information that was helpful other than checking fuses.
I'm new to the forum and hope I'm getting this in the right category. Thanks for any info, it will be deeply appreciated.
