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. \u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eEnhance your ride\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThis potent Pioneer's dual 4-ohm voice coils give you more wiring options when setting up your system.
