Reddit mentions of Monoprice 109437 5PRJX74047 Gold Plated Speaker Banana Plugs – 5 Pairs – Open Screw Type, For Speaker Wire, Home Theater, Wall Plates And More

Can use bare wire, but it's not the most secure/safe connection. Get open screw banana plugs and connect them with the port and your speaker wire (like so), can also be used on the receiver side. If you don't have a receiver, that's obviously where you need to start.

Is it just those two or are there others? If not, then it's just stereo.

(*See discussion below) The blue port is for a subwoofer, instead of RCA it uses a standard F-type coax cable (like for tv), so you need an F-type male to RCA female adaptor on the receiver end and the reverse wherever the subwoofer is/will go (unless there is an in-wall subwoofer already installed), as seen on the Amazon page, just buy the "Frequently Bought Together" bundle, you'd also need a female to male subwoofer cable.

🤪 you run wire in from the end.......

these?

Standard Stripped Speaker Wire. You could probably add some banana's if you want it pretty.

I vote for OPTION 2. Seems like you get more for your money with the sub. You could trim a bit off these totals by going with less expensive cables. 14-Gauge, 99.9% Oxygen-Free Copper + Banana Plugs = $37.72

OP from your comment sounds like you could use an old PC power supply since it puts out 12V, 5V and 3.3V.

On the ATX board just make sure to put some low amp fuses like 2 amps. Solder, Shrink wrap and LABEL to avoid plugging 12V into a mixing board.

EDIT: you could accomplish the same task much cheaper but using the 4 items listed above you would not have to modify the snake at all.
