3512-04S Car Audio Bass Bundle with RXA-T1, RWK81, RSST12 and Install Kit

This car audio bundle pairs a 12-inch shallow-mount subwoofer with a sealed enclosure, a two-channel amplifier, and an 8-gauge amplifier wiring kit for a compact vehicle bass system. The single 4-ohm voice-coil subwoofer handles 300 W RMS and 600 W peak, with a 3.375-inch mounting depth and 11.125-inch cutout diameter. An inverted Apex surround increases surface area for air movement, while spider-plateau venting directs cool air toward the voice coil and progressive suspension helps control excursion. The enclosure uses 5/8-inch MDF, fits one 12-inch shallow subwoofer, and has a stated 0.9 cu ft net volume. The included wiring kit lists copper RCA cables and a 60 A AGU fuse; the package also includes 12 feet of 14 AWG speaker wire, two spade terminals, and 10 metal drywall-style screws. Confirm available mounting space and amplifier configuration before installation.
