Collection: Subwoofers

Adding deep bass to a boat stereo means choosing between standalone subwoofers and all-in-one units, and that choice shapes everything else. DS18's HYDRO series and Boss Audio's MRG10W are passive drivers built to pair with a separate amplifier, available in 10-inch and 12-inch sizes and rated from 600 to 800 watts, with RGB lighting that suits open cockpit builds where the sub is on display. Fusion's Signature Series 3i takes a similar approach with CRGBW lighting and a sport-focused enclosure in grey or white. Aquatic AV goes a different direction with the SWA6 line, offering compact combined stereo and subwoofer units, some amplified and some with Bluetooth built in, which suits smaller boats or console installs where space and wiring simplicity matter most.

Before buying, confirm the cone size fits your enclosure or mounting cutout, and check whether the subwoofer is active or passive. Passive models require a compatible amplifier with enough power to match the driver's rating. For marine use, look at the enclosure material and grille construction since prolonged spray and UV exposure will degrade gear that is not purpose-built for it. Color choice is practical as much as cosmetic: white finishes read well on white hulls and in bright sunlight, while black suits darker installations.
