Alpine's Type-R subwoofers will bring big bass to just about any vehicle. The SWR-12D4 12" sub features a cone made from Kevlar® treated pulp - the same material used to make bulletproof vests - and its durable HAMR SantopreneTM surround allows for huge amounts of excursion. This sub was built for bassheads that want the best of both worlds: accurate response and otherworldly thump.
