3512-04 Dual 12-Inch Subwoofer Bundle with RD12 Enclosure and Installation Kit

Build a dual 12-inch car audio bass system with two 3512-04 subwoofers, a sealed enclosure, and the hardware for wiring the setup. Each subwoofer handles 250 W RMS, for 500 W RMS combined power handling, and has a listed frequency response from 28 Hz to 130 Hz. Each driver has a 4-ohm single voice coil and is recommended for an amplifier rated from 125 to 250 W RMS per subwoofer. The sealed RD12 cabinet holds both 12-inch subs in 3/4-inch MDF and provides 1.25 cubic feet of net volume per sub. An Inverted Apex surround increases surface area for greater air movement and SPL, while Spider Plateau Venting directs cool air toward the voice coil and a progressive suspension controls excursion at higher power. The included installation kit contains 20 feet of 14 AWG blue speaker wire, 20 screws, and four spade terminals for installing the drivers and wiring them to an amplifier.
