My 2000 Camry LE has a rear speaker that makes no sound. I looked in the
trunk and saw that one of the two wires that go down into the speaker is
loose and hanging outside the speaker. I don't see any way to fix it without
disassembling the rear shelf. Does anyone know a way? If not, is this a
repair I can do? If not, any idea how much it will cost?

I've had the car less than 3 years but more than 36k miles, so Toyota and my
dealer say there's no warranty coverage for this.
