Alpine's Type-R subwoofers will bring big bass to just about any vehicle. The SWR-8D4 8" sub features a cone made from Kevlar® treated pulp — the same material used to make bulletproof vests — and its durable HAMR Santoprene™ surround allows for huge amounts of excursion. This sub was built for bass heads that want the best of both worlds: accurate response and otherworldly thump.
