Wet Sounds ZERO 12 SUB KIT-S4 12" 400W RMS 4-Ohm Loaded Rotomolded Sealed Marine & Powersports Subwoofer Enclosure

The Wet Sounds ZERO 12 SUB KIT-S4 4-Ohm Loaded 12-Inch Subwoofer Enclosure Kit (MPN: ZERO 12 SUB KIT-S4 | UPC: 810042178946) combines Wet Sounds' shallow-mount ZERO 12 4Ω neodymium subwoofer (400W RMS / 800W Peak, XZ-B grille included) with a braced, weatherproof 28" W x 14" D x 8.81"/5.71" H rotomolded sealed wedge enclosure.

Designed to pair seamlessly with bridged 4-ohm channels on SYN-DX4, SYN-DX6 (600W Ch. 5/6!), HTX-2, or Sinister-SDX amplifiers—or in dual parallel pairs at 2 ohms—the ZERO 12 SUB KIT-S4 delivers deep 25Hz marine and powersports bass where traditional tall enclosures cannot fit.
