I just replaced mine yesterday (I have a 2001 so I donít know if it is exactly like yours).
I took my sound bar off to make it simple.
There are two torx screws on each end (t27, I think) under the cloth, remove them. Then disconnect the wiring harness on the sound bar, should be on the driverís side. You will see the harness once you unwrap the cloth from the sound bar.
Once you have the sound bar out there are 4 screws holding in each speaker and cover. Once you remove them the speakers will come right out.
Depending on where you purchased your speakers you will need to splice the wires or use the supplied harness adapter. I just spliced mine.
I put 6.5 inch speakers in mine, the holes in the new speakers were slightly off from the factory holes so I drilled my own using a 7/64 inch drill bit and uses the factory screws to install the new speakers.
Once you have them installed just put the sound bar back in, attaching it with the 4 torx screws and reattach the wiring harness.
