8" 600w Marine Loaded Subwoofer Enclosure Plus Passive Radiator TB8

The Kicker TB8 is an 8-inch tube-style loaded subwoofer enclosure sized for boats, trucks, or tight cabin corners where a full-size subwoofer box won't fit. Inside a thick ABS tube, a CompR woofer works alongside a matched passive radiator to move air more efficiently than the woofer could on its own, and a flexible mounting system lets the whole enclosure sit horizontally or vertically depending on available space. Spring-loaded speaker terminals speed up wiring, and a ceramic magnet motor paired with an advanced heat management system keeps the driver stable through extended, bass-heavy playback. This version runs at 4 ohms, handling up to 600 watts peak and 300 watts RMS, making it a better match for amplifiers that aren't stable at 2 ohms than the standard 2-ohm TB8. Signature double red stitching and included grilles keep the enclosure looking finished in builds where it stays visible rather than hidden under a panel. All the mounting hardware for both horizontal and vertical orientations, brackets, base, hook, and retaining plate, ships in the box. This is a compact way to add real low end to a smaller vehicle, boat, or tight-package build without needing a 2-ohm stable amplifier.
