Here's a side by side look at the control panel cutout and the speaker cutouts. (Please Note: The pieces were cut at separate times and a just shown here side by side for reference) You can't see it here, but the speaker support is marked of with the measurements of the speaker cutouts and the wireless keyboard receiver. (not yet cut) If you look really closely towards the bottom right of the picture (just under the right saw horse support) you'll see one of the pieces of wood cut out from the control panel. That hole in the center is where you drew your guide hole.
