couple of questions.

i have the 9006 or 6006e (6 disc stereo) also with the sub in boot.


1st of all - which size speaker are in front and back

2nd of all - if i want to replace headunit. do i just need a one that has the 6 disc option on it (if that makes sense) because i was thinking not just any old headunit would work because it needs the LOAD button on it etc etc so you can load 6 cd's
