3510-04S Pair + REC131 Dual 10-Inch Enclosure and Install Kit

Build a low-frequency system for a 2022-2023 Crew Max with two shallow-mount 10-inch subwoofers, a vehicle-fit sealed enclosure, and the core wiring and fastening pieces in one package. Each 3510-04S is rated for 300 W RMS and 600 W peak, with a 4-ohm single voice coil and a 3.375-inch mounting depth. Its 28 Hz to 130 Hz response and 83.7 dB sensitivity give clear figures for matching an amplifier and planning the system. The REC131 enclosure is made for under-seat placement in the specified Crew Max model years. Its sealed dual-10 layout uses 5/8-inch MDF, glued and stapled joints, silicone-sealed seams, and a sprayed bed-liner finish. The box measures 52.375 x 6.25 x 17 inches, with up to 4.375 inches of mounting depth. A separate installation kit supplies 20 feet of 14 AWG blue speaker wire, 20 metal drywall wood screws, and four spade terminals for mounting the subs and wiring the enclosure to an amplifier.
