It looks like Best Buy has stock of these two Polk Subwoofers back on sale now for $89.99-94.99. A few of us on here have hooked these up adding quite a significant improvement to bass for our games. No permanent modification such as drilling holes or cutting existing wires are required. All you need is some speaker wire and gator clips like this to clip onto the existing sub in the game and feed through the existing hole.
