Waterproof Speakers that float - "It floats, it totes and it rocks the notes!"

Step 2 Measure and cut container

Begin by measuring and marking where you will be placing the speaker grill. I did this by making a template out of paper so that it would be easier to trace the outline of the speaker grill and mark where the hole will be cut and the screw holes to be punched in with scratch awl. I also wanted to make the actual hole for the speaker as small as possible, while still allowing for the sound to resonate inside the container (also be sure to allow enough room to pass speakers through hole from inside). I have noticed that low end sounds are much better when the container is sealed. After marking both sides, it's time to begin cutting the holes and punching screw holes to secure the grill.
