If it's like the 268, there is a single screw on the front end on the bottom. It's tucked under the trim so it doesn't show.
Remove that and you can lift up the trim piece and bow it out. There is another faster at the back end that has a nut behind the gun whale, I just bowed the trim and hinged it upward on the rear fastener. I could get it high enough to change speakers
I would guess the 248 is similar
