I want to change a number of things in my avalon starting with a cd player. I have the XL version that does not come with one, instead there is a little box thing under the tape deck. How do you get this out? Would i have to remove the whole panel to get to the wires? I would also like to put some subs in there, nothing too big just like 2 10's in a low price range, anyone have any ideas for the subs and placement? Also the 4in speakers in the doors are about shot, so again any recomendations.
