5515-22 Pair with RDV15 Dual 15-Inch Vented Enclosure and Installation Kit

Build a car audio system focused on strong low-frequency output with two 15-inch subwoofers, a dual 15-inch vented enclosure, and the listed installation hardware. Each 5515-22 handles 400 W RMS and 800 W peak, with dual 2-ohm voice coils, a 19 Hz to 130 Hz frequency response, and 85.4 dB sensitivity. The source lists recommended amplifier power at 200 W to 400 W RMS. The enclosure is built from 3/4-inch MDF, tuned to 41 Hz, and provides 2.41 cu ft net volume per sub. Its external dimensions are 38 by 18 by 16.25 inches, with mounting depth up to 16.5 inches. Spider Plateau Venting directs cooling air toward the voice coil, and the radial ribbed T-yoke acts as a heat sink. The Inverted Apex surround increases cone surface area for greater air displacement, while progressive suspension helps control excursion and distortion at high volume. The package includes 20 metal drywall screws, 20 feet of 14 AWG blue speaker wire, and four spade terminals for enclosure installation and wiring.
