Here's what I have done. First I removed all of the non-used components from the stock stereo from the forward area of the rear hatch. I cut a piece of 1/2" plywood to fit in the space (approx. 32"x8"). Once I got th corners cut to fit, I hammered the top of the board where the two large studs stuck up and used those indented to drill holes to anchor those studs to the board.

Next I placed the amps on the board for fitment. Each amp is 8"x16".

Once the amps were in place I trimmed the foam filler panel to fit back in place.
