Don't laugh about that cartoon! I just did exactly that using an big gas powered wet saw. The fumes were pretty bad and I had to scoop up about 100 gallons of water from my living room floor, but 3 long trenches of 2" x 2" were dug out of my concrete slab which allows me to run cables under the tile floor from where the racks are located to where the speakers and Buttkickers will be positioned.
