Audio Systems: passenger side speakers not working, vw passat, side speakers

Question
i have a 2003 vw passat gls v6.

i noticed this morning that the radio didn't sound as balanced as usual and realized that none of the speakers on the passenger side were working.  any thoughts? i replaced the cabin filter (near the windshield on the passenger side) over the weekend.  is it possible i knocked some wiring loose while doing this?

thanks,
dave

HI:

I DON'T think that happend the plug goes from the radio to the passanger side under the carpet to the trunk and plugs in to the amplifier that is in the rear deck right side of the vehicle from there it goes to all 8 speakers

maybe if you pull the wires it got unplug from the radio

sorry i can not help more
