I was talkiing to boatnam2 and he suggested contacting Roz or Havasu Hangin. Please help. I have a new Stoker 224, with a Kenwood KDC X859 cd/mp3 player in the dash. 2 Boston Rally Series 6X9's in the bulkhead and 2 Boston Rally Series 6.5's in the side panels. The system is powered by 2 Optima blue tops. The 6X9's sound great but the 6.5's are very tinny, the dealer suggested builing boxes around the 6.5's and if I still wasn't happy they would trade them for 6X9's. I want to improve my system but am unclear which route is best for my application: 2 channel, 4 channel, 5 channel with a sub? From what I understand boats are different animals from cars and trucks? Without adding too much weight to the boat I want to build a clean hard hitting system, (The ghetto thump does not appeal to me.) Any sound advise or resources would be greatly appreciated Thank You Steve.
