5510-22 Dual 10" Car Subwoofer Bundle, RDV10 Enclosure, K2 Install Kit

The 5510-22 dual 10-inch car subwoofer bundle pairs two 400W RMS subwoofers with a dual-10-inch vented enclosure and the listed mounting and wiring parts. Each sub handles 400W RMS and 800W peak, with dual 2-ohm voice coils, a narrower surround profile that increases cone surface area, and progressive suspension that controls excursion. Cooling directed toward the voice coils and a ribbed yoke help manage heat during extended playback. The enclosure is built from 3/4-inch MDF, uses spring-loaded terminals, and is tuned to 42Hz. Its listed dimensions are 14.25 by 32 by 12 inches, with a 1.1 cu ft net volume per sub. The package also includes 20 metal screws, 20 feet of 14 AWG blue speaker wire, and four spade terminals, giving installers the components named in the package contents for mounting and wiring a dual-sub setup.
