hey bud, you really only need the sill plates at the edge of the carpet next to the door. other than that, the seat and seat belt bolts will hold it in place. plus a little spray adhesive if you wish. but if you're doing more with your sound system, i'd leave it un-glued so you can route wires under the carpet easier.
