Long Beach, Calif. - Pioneer launched a microsite with pictures and videos to record the activity at the fourth annual Pioneer Sound Build-Off organized by the company's car electronics department.

The event, held in La Quinta, Calif., pitted installers from around the country in a contest to determine who could create the best sound system from Pioneer's reference Stage 4 car audio components. A dozen installers competed for the $10,000 grand prize, won by Cartronics of Santa Rosa, Calif.

The photos and videos display all of the competitors' installs.
