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-W10D4 10 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.

The R-W10D4 can handle up to 750 watts RMS, so be sure to choose a suitable amplifier as these bass monsters definitely want lots of power. Its dual oversized 4-ohm voice coils offer wiring flexibility you'll appreciate as your system changes and grows, so you can always pull maximum power from your amp. It works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.
