This 4x4 Chevy Colorado Crew Cab has Pioneer's Premier Head Unit with iPod interface, 6.5" Diamond Audio component speakers in the front doors and 6.5" 2 way JL speakers in the back doors. It also has a JL 10" sub Stealth box on the floor in the back seat area. There are 2 JL amps mounted behind the back seats. One amp has 300 watts powering all four speakers in the truck, while the other amp is 250 watts powering the JL 10" sub Stealth box. the clarity and loudness of the system is sick! I get lots of head turners. I just got the chrome side assist steps in and installed them myself with a chrome gas cap. I also have a K&N cold air intake and a throttle body spacer installed. It has the 48" Fire and Ice LED bar under the tailgate and 64" Rig lights that are amber LED lights that flash when turn signals are on.. its pretty sick looking. Its the cloest thing to having under glow without police pulling me over.
