What a difference an extra $50,000 makes. Add that to the base price of an '05 H2, and Tom Kamerer spent around $93k on his over-the-top customized SUV. The cost might be worth it, based on the plethora of packed-in products straining the Hummer's respectable payload capacity, thanks to the industriousness of Tom Bostic, aka Tommy Built, who built the vehicle in Pasadena, Maryland, with helping hands from Cris and Arthur.

Let's take a gander at this H2's mobile entertainment suite by starting with the howitzer in the back. Kamerer wanted something different from all the other custom Hummers out there, so Bostic suggested they build the audio system around the 369-pounds, 23-inches long, 22-inches wide (cone diameter) MTX JackHammer subwoofer that is mounted in a futuristic-looking enclosure, all of which is secured in a maroon rollcage for stability.

The rollcage was made with the help of Mad Dog 4x4. Opening the rear hatch reveals the JackHammer audio launcher surrounded by two 10-inch MTX Thunder T8500 subs, a pair of MTX TA-92001 MTX Thunder amplifiers for the JackHammer, twin TA 7402 amplifiers for the 10 inchers, and a couple of TA 7402 amps for the front and rear speakers. All in all, the system delivers 8,400 watts. The JackHammer is so large that it pumps out mega bass even at low volumes, so the two 10-inch subs act as stand-ins when the pounding of the JackHammer gets to be too much. Gray suede lines the cargo area where you don't see maroon fiberglass or steel tubing.

Two 7-inch Vizualogic headrest monitors in the rear seats are visible from the back. Three 7-inch monitors hang down from the opened rear hatch in a maroon fiberglass enclosure and a rearview camera centered above that array. Two 15-inch monitors were hidden in the rear-side glass and are invisible until they are turned on, along with a custom panel that lights up with a Fox Racing Shox 360 and an MTX logo hidden in the rear glass. Another rearview camera is mounted on the outside of the gate.

The maroon rollcage extends into the second row of the seating. Beneath those seats lies a maroon-ostrich-leather-lined box containing two Power Acoustic DVD players, an Xbox, and two Pac video amplifiers. Two 7-inch Vizualogic headrest monitors, with their own integrated DVD player, are mounted in the front seats. Between them hangs down two 7-inch monitors that are stacked atop each other and swivel independently to the left and right.
