Looking at the boat builder and noticed a couple new options and wondered if anyone had experience with them. How do the Roswell speakers compare to the kicker system and what head unit does Roswell use? i can't tell if the Roswell system is for the cladded arch or open arch. Anyone use the Giant turbo ski swing? I saw they video and wondered if it would fit all horsepower options. i am looking at the Mercury 400 racing engine.
