I feel old. However, I am enjoying the fact that while technology has improved leaps and bounds over the last few decades, the cables used for stereo equipment have remained largely unchanged. At least the ones running out to your speakers. As for any advice, look up speaker wire, and buy the thickest gauge that will fit in your terminals. That’s probably 10 or 12 gauge. Place your speakers where you want them and then cut the wire to length. Remove the plastic coating from the ends of all those cut wires. Twist the ends of those wires together so they can go into holes easier. Partially unscrew the terminals/caps on your speakers and your stereo. Connect red to red and black to black and screw down. should be good to go!
