5515-44 15-Inch Subwoofer System with dB12 Amp and RSV15 Enclosure

Build a vehicle bass system with a 15-inch dual 4-ohm subwoofer, mono amplifier, vented enclosure, and the listed connection and installation parts. The 5515-44 handles 400W RMS and 800W peak, with a 19Hz to 130Hz frequency response. Its inverted surround increases cone surface area, while spider plateau venting directs air toward the voice coil and a ribbed t-yoke helps dissipate heat. The included RSV15 enclosure provides 2.6 cu ft net volume, 32Hz tuning, a single 15-inch opening, and 3/4-inch MDF construction. The 4-gauge amp wiring kit includes copper RCA cables, a 60A AGU fuse, and split loom. The package also lists 12 feet of 14 AWG speaker wire, two spade terminals, and ten metal drywall screws. The mono amplifier is rated at 500W RMS, while the subwoofer lists a recommended amplifier range of 200 to 400W RMS. Compare those ratings when setting up the system.
