How to get to rear speakers in 2002 ford taurus?

Ok so i bought some aftermarket speakers to replace the stock ones in my 2002 ford taurus lx i got the door speakers put in fine and am now trying to replace the rear ones but i can't seem to figure out how to get to them i found crutchfield instructions online and it says there's hooks underneath the bottom seat that you have to undo and then the back cushion just folds down this is find and dandy but it dosen't say where the hooks are or how to undo them as you can't really get underneath the seat if anyone has any info i would apprecite it thinking i may just have to take a box cutter to it

If you mean the ones in the back by the back window you may have to go through the trunk.
