Expert Installation Advice
Power Management
Match amplifier output to speaker RMS ratings. Use marine-rated power cables. Ensure secure connections to prevent vibration-related failure.
Placement
Mount speakers in locations with adequate air volume for infinite-baffle models. M6 10" subwoofers require at least 2 cu. ft. of air volume behind the mounting surface.
System Expansion
Use NMEA 2000 certified source units for integration with helm displays. This allows audio control from Simrad, Garmin, or Lowrance units.
