We welded up a rack to securely mount a couple of additional batteries to aid with the amplifier’s current demands. A total of three optima Red Top batteries were used, and all were strung together with a 1/0 power wire.
Kenwood's DNX 9960 was selected for navigation and DVD viewing purposes. We remote mounted an auxiliary USB port in front of the shift lever along with the Rockford PEQ bass knob.
Under the rear seat, we mount the two monstrous power amps. A vinyl-covered trim panel was fabricated to conceal the wiring and help the 6 fans that we added below to aid in keeping the amps cool when the 4 wheeling gets tough.
Vinyl trimmed amp rack under rear seat area.
The front doors were reworked to allow additional speakers to be added. There are 3 sets of Rockford Fosgate T2 6.5" mid-bass speakers in each front door, enhancing the Hummer H2 SUT sound system upgrade.
The door pods were constructed from fiber glass & MDF then covered with a matching vinyl. Behind the scenes and out of sight, we added 160 square feet of Second Skin sound-dampening material to the doors, headliner, and floorboards.
To complete the Rockford T2 speaker set, we modified the A-pillars and mounted the three T2 tweeters.
The rear door panels remain in stock with the addition of the T2 tweeter up top, and the Rockford T2 5.25 woofer is behind the OE grill in the stock location.
The H2 SUT has a built-in blow-through that we took advantage of. Using 1" MDF and Plexiglass, we made a custom ported enclosure for the 2 RF T2 15" woofers.
The 2 woofers and the enclosure port fire through the mid-gate of the H2. With the addition of some LED lighting and vinyl trim panels, it looks as good as it sounds.
Dropping the tailgate reveals the back side of the T2 15s visible through the 1" thick plexiglass. We trimmed the inside of the enclosure in black and grey vinyl with red piping and added some more LED lights inside. Notice the custom integrated center brace and the H2 logo fabricated out of 1/4" plexiglass and painted red. To wrap up this Hummer H2 SUT sound system upgrade, the rear trim panels were constructed out of 1/4 black ABS plastic to match the factory bed panels.
Hummer H2 SUT Sound System Upgrade in Arizona
This H2 isn’t an all-show trailer queen. The owner 4 wheels this sick H2 on a regular basis and wanted a system to match, built over the top and durable, resulting in a remarkable Hummer H2 SUT sound system upgrade.
