Circular motorization, how can I do it?

I want to make a subwoofer box (around 40 lbs) spin. It doesn't have to be super fast or anything. Maybe one rotation in under a minute. My plan is to have 3 of these boxes spin seperately. The wiring is not the hard part for me, but I can't seem to figure out how to motorize it. Linear actuator? Window motor? Really strong 12v motor with custom gearing?

So like a 12v motor from a cordless drill? Any ideas of what rpm and torque I should look for?

Would a flange bearing like this (1.5" I.D. is the largest I can find) work for connecting the box to the motor plate?

You might be able to use a serpentine system, like the one that turns all of your accessories on your car's engine. If done correctly you can use one motor (possible from an electric fan or something). You could find the pulleys at a junkyard, buy your belts from the parts store and get the three speakers to spin in different directions and timing (if that's what you're looking to do). Never tried, but it sounds good in theory.Nothing is impossible!

How are you going to wire it so that it doesn't get twisted up as the box spins?

Always check info with a digital multimeter.

I promise to be good.

I've been sick lately, sorry I won't be on much.

Wiring would be done with 2 metal rings on one side. The other side would have 2 spring loaded metal contacts (sliding van door contacts). I have not tested this, but I assume it will work. If for some reason, a solid connection is not made, I could always just use regular wire and program them to spin approximately 10 times in one direction and then turn around.
