So even though it probably would have been fine, I just kept thinking that I'd have a problem down the road if I buried the subwoofer cables in sand. I made a quick run to Lowe's and picked up some 3/4" conduit, a few elbows, and a new 1" spade bit for the drill.
I cut a couple of pieces of the conduit to about a foot in length.

Added the elbow:

And then bored out the hole in the frame to 1" and inserted the conduit.

One the sand was pushed back into place, I had a conduit to hold the cable.

I duplicated the steps on the other side of the stage and filled the middle sections with batt insulation. Next, I measured for the locations on the subfloor where the cables would pass through, drilled some 1" holes, and then pulled the cables through.

I planned to seal up the stage tonight, but noticed that i have a VERY slight overhang on the plywood. I think this might cause an issue with the veneer and bullnose, so I may shave a little off tomorrow before closing it up. I picked up a few flooring samples while out as well this weekend and I think I've settled on a dark hickory laminate. I'll get a picture of it up this week.
On a side note, I noticed a LOT of echos when standing in the front corners. I had a lot of luck with the Chameleon bass traps in my last theater, so I'll probably add a few to the side walls up front once things are done.
