Memphis based Sound Waves is definitely a Pioneer Sound Build Off veteran. Mike Irwin told 12voltnews.com "We competed in the initial Build Off and finished just out of the money, but it was a great learning experience. We skipped a year and then finished in 2nd place last year in Long Beach. We are putting all that experience into our '07 Yukon project for this year's Build Off 4.0." The interior of the Sound Waves' lowered Yukon was virtually stripped to the bare metal. The installation team of John Irwin, Travis Williams, Mike McHughes and Alex Barger wanted as much real estate as possible to showcase the Stage 4 products and concentrate on the sound quality portion of the competition."
