Having a sudden lack of bass in my '06 Avalon (JBL Synthesis), popped the trunk and took a look at the subwoofer. It looks like a connection problem/bad wire inside the speaker.
Element looks pretty standard to me and it seems to be bolted with 4 bolts to the read deck. I need to remove the cover from rear deck, or at least the speaker cover but could figure out how to pull it off.
I tried to pry it off with wide knife but stopped when I started to hear the cracking sound.. don't want to mess up the cover.
Does anyone know how to get access to the rear speakers in 06 avalon?

A picture would be great..
