Alpine R-W10D4 10inch R-Series Subwoofer (4ohm)

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 the excursion. Alpine built this sub for bass heads who want the best of both worlds: accurate response and otherworldly thump.
