5512-44 Pair + RDV12M + K2

This dual 12-inch car subwoofer bundle pairs two 400W RMS drivers with a vented, dual-chamber enclosure and the listed hardware for installation. Each subwoofer handles 800W peak and has dual 4-ohm voice coils, with a recommended amplifier range of 200W to 400W RMS per driver. The enclosure uses 3/4-inch MDF, has precision-cut mounting openings for two 12-inch subs and is tuned to 41Hz. Spider-plateau venting directs air toward the voice coil, while a ribbed yoke helps manage heat during extended playback. A progressive suspension controls cone movement at high power. The package includes 20 feet of 14 AWG blue speaker wire, four spade terminals and 20 metal drywall screws, bringing the two-subwoofer setup and its core installation materials together for a vehicle audio project.
