After an exciting day of judging, the 2010 Chevy Camaro by Cartronics was declared the winner and awarded a $10,000 check plus the Pioneer Sound Build-Off championship trophy.   The 1999 Mercedes CLK 430 by Sound Sensations was awarded second place and the 2001 Chevy Corvette Z06 by Metro Audio Dynamics placed third.
