Check out this AMAZING sounding boat that we recently finished. There are speakers just about everywhere... There are EIGHT 8.8" coaxial speakers, FOUR 7.7" coaxial speakers and TWO 10" subwoofers, all JL Audio M6--top of the line, of course. Powered by THREE JL Audio M800/8 amplifiers. The source unit is JL's MM50 multimedia bluetooth unit.
