This is Chris Dean's Chevrolet "SPL-10" Pickup.  This rig features four TREO Engineering CSX18 eighteen-inch subwoofers powered by eight(!) HiFonics Colossus amplifiers.  It takes a lot of juice to keep those big A/B monsters running at full tilt, so it is a good thing there are eight batteries to go with the eight amps under the tonneau cover.
