this is pretty straight forward install, especially if you've do this before. my 2002 sentra was almost exact same procedure.

these are pics with some instructions added.
the speakers are 6.5" for those who should know. and they do require brackets either purchased or manufactured at the time of install.
front door has about 2-1/8" depth before hitting the window.
rear doors shouldn't be a problem unless you have massive magnets on your drivers.
look through all pictures before starting, everything is essentially in order.
msg me before you start if you have questions.
Aaron.
