Buying Guide

Power handling and RMS

Match subwoofer RMS and peak power to your amplifier to avoid distortion and ensure reliable performance under sustained loads

Enclosure type and space

Choose between sealed, ported, or shallow-mount designs based on available installation space and desired low-frequency response

Impedance and wiring

Check the subwoofer's impedance (2Ω vs 4Ω) to ensure proper compatibility with your amplifier channel configuration and wiring plan

Marine-grade protection

Look for waterproofing, UV-resistant cones, and corrosion-resistant terminals to withstand saltwater and sun exposure

Integrated amplification option

Consider built-in-amplifier subwoofers for simpler installs on small boats where running extra amp wiring is difficult
