I saw that boat in the back ground. Im sure WCCC does everything from wild stuff to a simple head unit and speakers. So the chances that it was just getting a simple system is very good.
That being said. I saw the Shack-alack. I thought they did a awesome job on it. A place like WCCC that does alot of car's and as far as I know hasn't done alot of boat's I would be worried about. I know they have some talent there but IMO if you don't wakeboard and or have a boat and use it the way we use our boats you have no idea how to install a huge system in a boat. I could see them doing somthing super cool to a boat and at the same time making it usless. Kind of like the CES cars/boats. Cool 2 look at but usless. If you don't know how weight effects a boat and where some boats are sencitieve to weight you can destroy the way a boat drives by simply install to much equipment in the wrong places. Case in point did anyone see the ARC audio boat. Awesome build ton's of equipment first class. When it was finished the boat wouldn't come out of the water! It has so much audio equipment stuffed into every corner you couldnt get it out of the hole.
The Boat Alpine did a few years back IMO was Awesome. Out of this world but it still worked. You could take it out and use it.
