3512-04 Pair with dB12 Amp, RD12 Enclosure and RWK41 Wiring Kit

The 3512-04 pair and included 500W RMS mono amplifier form a dual 12-inch car audio bass package for adding low-frequency output to a compatible vehicle system. Each 4-ohm single-voice-coil subwoofer handles 250W RMS, for 500W RMS across the pair, while the amplifier is rated for a 2-ohm load. Inverted Apex surrounds increase cone surface area for air movement, Spider Plateau Venting directs cooling air toward the voice coils, and progressive suspension controls excursion to reduce distortion. The RD12 sealed enclosure provides 1.25 cu ft net volume per subwoofer and uses 3/4-inch MDF with precision-cut openings; it measures 13.25 x 13.25 x 32 inches. The included 4-gauge RWK41 amp wiring kit comes with RCA cables, and the package also lists 20 ft of 14 AWG blue speaker wire, 20 metal drywall wood screws, and four spade terminals. This combination brings the subwoofers, enclosure, amplifier, and listed wiring components together for one installation plan.
