This little 8-inch beast packs enough punch to shake your ride. The Sundown Audio X-8 v.4 is built for people who love deep, clean, and hard-hitting bass, but don’t have room for a massive sub. With 1000 watts RMS power handling and a tough Dual 4-Ohm voice coil, this sub can handle serious power all day long. The high-excursion design means it moves more air for louder, lower bass without distortion. Whether you’re cruising with smooth beats or turning heads with heavy drops, this subwoofer delivers.

• Massive Power Output – 1000 W RMS with even higher peak capability for serious bass impact.
