I had Soundcrafters Daytona Beach install a Kenwood Excelon DDX9904S, and rear camera in my Mercedes CLK350. The '08 CLK350 had the factory Harman Kardon sound system. Moe Sabourin and his team accomplished what everyone else said could not be done; Installing a new sound system utilizing the existing factory Harman Kardon amplifier and speakers. The installation is superb to include soldering, and heat shrink. As an A&P mechanic, I am impressed with the installation from the technical perspective. No issues the last three months. The cost was reasonable and the performance of this unit is fantastic. Thanks Moe and Crew. I would Strongly recommend Soundcrafters Daytona Beach to the discerning auto audiophile.
