Ok, I haven't done this before, but I can give you a bit of insight.

First of all, you will need an amplifier. Typically, to my knowledge, 'receivers' actually do act as amplifiers, so you will be fine there. JUST MAKE SURE THE OHM rating matches!

As I said though, a receiver depends. Now seeing that you want to stick this into a cart, (bot?), you will want to use a DC amplifier, be very careful with your choice.

To my knowledge, you might also need a console of sorts, not sure what to go about there, but good luck.
