Yoji, I have seen some arcade cabnets with speakers on the sides of the monitor, but i have to say that nohing makes the experience authentic like hearing the sound come down at you. It creates the encompassing sonic curtain that allowed you to play a game in a packed, noisy arcade, yet concentrate only on your game! It sounds like you have a standard 2.1 (left & right speakers and subwoofer.) computer speaker system. If this is the case, then trust me, CUT THE WIRES and splice in more cable to make them stretch up to the marquee. Go to your local home depot or radio shack and buy speaker wire tha is approximately teh same gauge as the original wire. You may not even be able to find wire of such a high gauge (computer speakers typically use 16 or 18 gauge wire.0 but don't worry, just get the closest thing you can find and do like horseboy says. Twist and tape! you're done and it makes teh cabinet authentic!
