5512-22 Pair + RD12 Sealed Enclosure + Install Kit

Build a dual-subwoofer car audio setup with two 12-inch dual voice coil woofers, a sealed enclosure, and the hardware and wire for installation. Each 5512-22 handles 400 W RMS and 800 W peak, with dual 2-ohm voice coils and a 25 Hz to 130 Hz frequency response. The 3/4-inch MDF enclosure has 1.25 cu ft of net volume per subwoofer, and its 13.25 x 13.25 x 32-inch exterior dimensions help with fit checks. The included kit supplies 20 metal screws of the drywall wood-screw type, 20 ft of 14 AWG blue speaker wire, and four spade terminals. Spider Plateau Venting directs air toward the voice coil, while the Inverted Apex Surround increases cone surface area for greater air displacement. Progressive suspension controls excursion at high power, supporting cleaner bass during demanding playback.
