Blue Show XterraXterra AudioThe audio install consists of a Pioneer 930 Head Unit, Infinity Perfect Component 6 1/2s for the front speakers, Infinity Reference 6 1/2 coaxials in the rear passenger doors, and Infinity Kappa 6x9 2 way coaxials. Three amps run the system with a Rockford Fosgate 300x running all mids and highs. The mids and highs are accompanied by a set of four Infinity Perfect 12.1 subwoofers powered by 2 Rockford Fosgate Power 1000BD amplifiers. To supply ample power, 2 US Acoustik 2.4 farad capacitors were added to provide power for the 1000BD's along with an Optima Battery. The amp rack was put on industrial strength rollers and the rolls out for display. PerformanceThe engine performance was upgraded by switching the factory air box with a Jim Wolf Technologies Air Intake System. For better traction I added Nitto NT555 around 18" Driv Plague wheels. To increase the flow of the exhaust, a Stillen Exhaust was added as well.
