l need to know how to get old ones out. l wanna replace 6x9

You will need to remove them from the top. To do this, u will need to take the shelf panel off that covers them. It is held in place by 2 srews at the front, & should have locating pins (or might be tabs that snap in place in the back) to hold it in the back.

If u have folding rear seats, u should be able to fold them down & do this, if u do not have folding rear seats, u will probably have to remove the seat back, which is held in by screws at the bottom, & then slides up off of retainers at the top. The screws at the bottom also hold the seatbelt buckles in place, so make sure u get them back in place when reassmbling everything.

To get to the screws at the bottom, u might have to remove the seat bottom cushion, which is held in placy by a retainer. To release it, lift straight up on the seat bottom. (some seat bottoms, u have to push back & lift up, but if l remember right, these just lift straight up to release from the retainers)
