removal
1. Remove the center armrest and upper bulkhead panel(speaker housing).
2. Remove the bulkhead L&R panels behind seats. May need to do this first rather than second.
3. remove the 5 screws, then disconnect the 2-P connector from the floor wire hardess.
4. Remove the 4 screws, then take the rear speaker out and of the center bulk head panel.
If you need, I can copy and email you the page out of the service manual for you.
