how do i take out the rear card board to get to the rear speakers in a 05 cavi?

What you do is first fold down your seats and take off the two plastic triangle peices that are right there, then take off all the plastic peices on top of the rear deck cover (you know the seat belt covers, child seat covers, things like that) make it so there is no plastic at all on top of that rear deck. Then from there just kind of wiggle it out, it will take some force to get it out. Most people say to take off the rear 1/4 pannel covers around the side windows, but it's not nessisary. Hope that helps you man, take care.

yea that helps alot thanks dude
