yeah those are the amp wires. there will be a power, a ground, a wire to turn the amp on (probably blue in color). And there are the two RCA cables for sound
Right idea here but colors are wrong. in your case the blue wire would be correct on this but your yellow wire is more than likely the + lead off battery(red in this image) and the yellow leads in this picture are actually the 2 audio plugs in your picture. Man, I hope this makes sense. If you lived close to me I woulda been more than happy to drop by and help explain to you in person.
Vegas 2 players were obviously hurt a lot by this change, but if it was costing too much time and resources to set up the Vegas 2 section of the event, then we can only hope that same energy is channeled into Halo, Gears, and WoW Gold. And hell, online circuit is not -that- bad. It is some of the time about World of Warcraft Gold.
