cargo

i have a 2008 equinox, how do you remove the passanger side cargo pannel where in a sport edition there would be a sub. i want to make a custom box to fit in there. or where can i just get the shell to hold the sub in.
thanks

Check with the dealer parts department, maybe the two types will interchange? Usually the trim around the panel will need to come out, then it's held in by spring retainers and/or plastic push retainers.
