Now, that I think I know why my right rear speaker is buzzing (probably a pinched wire), I'm wondering what route the wires follow from the radio to the right rear? Anyone been there before?

Thanks,

Bob

 

Anyone have a wiring diagram (04 TL AT) that shows the radio wiring?

Thanks,

Bob

 

No, but the wires you're looking for start at the amp located under the passenger side kick panel forward of the doors, and follow the door sill straight back, then over the rear wheel well and through a small port to the trunk. If you think it's a pinched wire, follow all the wires from front to back, there's only one loom along that door sill, really. You may have to remove the rear seat to get at all the wire. I'd also suggest a panel popper.
