Moving inside the Hummer is where Jim went a little overboard. By completely removing the second row of seats, David Baldwin of Pro Motorsports built a wall subwoofer enclosure. Housed in that wall are four Kicker 15-inch L7 SoloBaric subs pounding any and everyone into submission. Powering those speakers and the eight sets of Kicker RS65.2 components are four Kicker amps, two 800.2 and two 2500.1. That much power, combined with an interior stuffed with Dynamat, made the Hummer unbelievably loud. Helping Jim drive to and fro, a Magellan GPS teams with a PAC stereo integration harness. The Sedona Red leather adds to the newfound elegance of the interior.

It's big, it's bad, but best of all: this Hummer is a Best of Show winner. We told you, Jim knows how to build 'em. Be on the lookout, as we have several more of his projects planned for print in '08.
