I have a 2003 Silverado crewcab with Bose. About a week ago I noticed the drivers side was very quiet.

I checked the speakers and both left doors speakers are silent but the tweeter in the pillar works perfectly. The speakers were working fine previously so I know they didn't just both die and the fact that the pillar tweeter is working makes me think it's not the radio or amp.

Does anyone know where the door speakers meet after the tweeter? I'm assuming it's a wiring issue but if anyone has clues just let me know.
