when u buy the installation kit, it comes with a pocket for the second din

 

dude, i vote eq. i know there are some who don't need an eq, but when i got my first one, and was able to tune/control my system, i was hooked. i don't hook up any system w/o an eq anymore.

if u go that route, don't get sliders. they're ugly. i like **** eq's. even tho most eq's are only half din, they still look nice mounted under the hu.

OR u could get an indash screen/dvd player combo!
