2006 GMC Sierra - Custom Truck - Audio Upgrades

Then, Modern Audio in La Habra stepped in and created a wild audio and video system for the truck. After lining the door panels with Dynamat, Randy Medina created custom speaker pods for the 6-1/2-inch Cutting Edge Audio speakers located in each door and rear extended cab doors. Randy also built a subwoofer enclosure in place of the rear bench seat that now houses three Thrasher 12-inch subwoofers. Powering all of this audio are three Cutting Edge Audio amps mounted inside a plexiglass enclosure on the back wall of the cab. Monitors were installed into each sunvisor, with a 15-inch screen hanging from the suede headliner. Entertainment is provided by a Pioneer AVIC D-1 and a Play Station 2.

Entertaining guests is no problem, especially at sporting events or at the river, once the ARE tonneau cover is opened. A huge enclosure houses two more Cutting Edge Audio amps, two Saber 15-inch subs, three 12-inch subs, and a 32-inch LCD monitor. The enclosure was coated in Diamond Liners spray liner with a brushed graphic to match the paint scheme. Tailgaters also get to enjoy the Freedom Grill that slips into the Hidden Hitch and provides instant BBQ fun. Radi's Upholstery in Garden Grove added black ostrich inserts to the black leather seats, then also wrapped the steering wheel in black suede. Black suede was again used to cover the headliner, visors, and grab handles. The dash was smoothed, painted, and a carbon-fiber dash bezel completes the custom interior trim. The GMC now looked and performed on a whole new level, thanks to some talented folks and generous sponsors. So, what is next for this Sierra? Could a fifth version of this fullsize be in the works? Stay tuned, the future looks bright.
