I am trying to get the speakers in my car working correctly. The right rear speaker is a lot quieter than the left rear speaker. I switched the speakers from left to right and it still is quieter on the right side. I looked over all of the wiring and it looked fine. What could be causing this?

 

you could have your head unit faded&balanced away from that speaker.

 

I checked and the head unit is not faded away. Any ideas?

 

i had a smiler problem... someone had bolted the seat down on the speaker wire and it was grounding out. That being said follow the wire from point A to B and look for any exposed wire, replace if necessary.

 

I agree, I have had that happen also.
