This is my second question in a row and I feel like a complete noob at this sometimes.
1. Sorry if this is the wrong section.
2. Sorry if you don't deal with what I'm about to ask - its more speaker than headphone related
I'm not sure if I'm allowed to post links such as this. But this is what I'm looking at.

I have two loudspeakers - 8ohm, 80 watts, and right now they're being powered by a large receiver, not a small 12v DC one like in the link.
As I understand it. 12volts - 80 watts, the speakers would have to be less than 1ohm.
Given 8 ohms, this would power them less than 20 watts each. Is this correct
I know a lot of you are going to cringe that I'm even using them, but I need to make these play for a large hall, and the people in it are really not sticklers for the sound.
I just don't understand how a small little 12v DC gadget that usually powers things like phones, can possibly power those.
Maybe someone could also give me the basic. (BASIC) formulas for understanding these types of things.
And what numbers I need to look for on a speaker/receiver --- ohms, volts, watts, amps? etc
