The TS-A301D4 12" subwoofer handles up to 500 watts RMS while pumping out loud, clean bass. This sub features Pioneer's Honeycomb IMPP™ cone for exceptional strength and a dual-layer, fiber and reinforced elastic surround that supports the woofer during cone excursion for accurate, hard-hitting bass notes when you crank the tunes. Enhance your ride This potent Pioneer's dual 4-ohm voice coils give you more wiring options when setting up your system. Throw one or two of these subs in your ride, power them up with a nice amp, and you'll understand — whatever you listen to, great bass will make it sound much, much better.
