Package Includes: (1) Rockville Punisher 12D2 12" 5600w Competition Car Audio Subwoofer Dual 2-Ohm Sub; (1) Rockville RBS12 Single 12" 2.6 cu.ft. SPL Vented/Ported Subwoofer Enclosure Box; 10 Drywall Wood Screws (Wood screws are the type of screws; the screws are actually made of metal); 12 Feet of 14 AWG Blue Speaker Wire; 2 Spade Terminals. Punisher 12D2 power & cooling: The Punisher 12D2 features a 3" 4-layer aluminum voice coil rated up to 250 °C, a double-stacked 246-Oz Y35 magnet, and an oversized aluminum heatsink ring for thermal control. Rated 1,400-Watts RMS (2,800-Watts program/5,600-Watts peak) with 28 mm one-way XMAX for deep, clean excursion. Dual 2-ohm coils enable flexible wiring for high-output mono amps while the cast aluminum basket keeps everything rigid at extreme SPL. SPL enclosure advantage (RBS12): The RBS12 single 12" SPL vented enclosure is precision-built in the USA from 3/4" MDF with a 2.6 cu.ft. net volume and a 43 Hz tuning for strong street-friendly punch. Heavy carpet wrap, gold spring terminals, glued/stapled seams, and silicone-sealed joints minimize flex and leakage, converting amplifier power into real output. Sized for today's big motors and deep baskets, it's voiced to get louder than generic boxes. Clean install & wiring kit: Included hardware speeds a tight, reliable build: 10 drywall wood screws for clean baffle bites, 12 feet of 14 AWG blue speaker wire for low-loss runs, and 2 spade terminals for secure connections. The Punisher 12D2's cutout is 11.22" with 7.48" mounting depth, and the RBS12 accommodates deep subs-making it straightforward to assemble an air-tight, high-current signal path from amp to driver to SPL enclosure. Real-world results: The Punisher 12D2's non-pressed paper cone, thick foam surround, and 0.9 mm PP dustcap deliver hard-hitting bass for hip-hop, EDM, and rock without muddying vocals. Vented T-yoke cooling, high-temp black glue, and a 3-layer spider keep performance consistent on daily drives or demo days. Pair with a quality monoblock at the proper impedance and let the RBS12's tuning translate wattage into chest-thumping output. Build a serious single-12" bass system with matched components. This bundle pairs the Rockville Punisher 12D2 competition subwoofer with the RBS12 2.6 cu.ft. SPL vented enclosure and a complete single-sub install kit for a clean, secure build.
