5515-22 Pair + dB13 Amp + RWK41 Wiring Kit + RD15 Enclosure

This car audio subwoofer bundle combines two 15-inch 5515-22 subwoofers, a mono amplifier, a 4-gauge wiring kit, and a sealed dual-sub enclosure for a high-output vehicle bass system. Each subwoofer handles 400W RMS, for 800W RMS combined power handling, while the amplifier is rated at 750W RMS at 2 ohms. That falls within the pair's stated 400 to 800W RMS recommended amplifier range. The subwoofers use dual 2-ohm voice coils, Spider Plateau Venting, and an Inverted Apex Surround, with a progressive suspension to manage cone movement at high power. The amplifier adds an adjustable 12 dB/octave crossover, a 15 to 55 Hz subsonic filter, phase control, bass equalization, and a dashboard subwoofer remote. The RD15 enclosure is listed as a sealed dual 15-inch, 2.1 cu ft box made from 3/4-inch MDF. The RWK41 kit includes RCA cables, and the package also has 20 ft of 14 AWG blue speaker wire, metal screws, and four spade terminals. Review the enclosure's fit and confirm the installation wiring before mounting the system.
