Buying Guide

- Profile and mounting: Measure under-seat clearances and confirm ventilation and mounting hardware compatibility.
- Weather resistance: Look for marine-grade enclosures, IP ratings, and salt-fog resistance for longevity.
- Integrated vs. external amps: Built-in amps simplify wiring but may limit upgrade options; external amps can offer more headroom.
- Input options: RCA and high/low level inputs enable compatibility with a range of head units and aftermarket systems.
- Sound tuning: Subwoofers with adjustable bass boost and low-pass filters help tailor bass to different boats and listening areas.
