For those who like it loud, Alpine salutes you! Their legendary R-Series subwoofers are made to bring powerful bass to just about any vehicle. The R-W12D4 12″ sub features a cone made from Kevlar® treated pulp — the same material used to make bulletproof vests — while its durable Santoprene™ surround allows for huge amounts of excursion. Alpine built this sub for bassheads who want the best of both worlds: accurate response and otherworldly thump
