KICKER "Kicker's 51PTRTP12 powered subwoofer enclosure combines a 500-watt amplifier with a low-profile CompRT 12"" subwoofer and a 12"" Kicker reFLEX passive radiator in a downward-firing box that brings Kicker bass power to the crowded spaces of today?s cars and trucks. The passive radiator reacts to the air pressure produced by the active sub, adding extra low-end thump without the noise of a ported enclosure."

Features

• High- and low-level inputs let you connect the enclosure to any system, while the included wired remote knob lets you adjust bass intensity from the driver's seat.
• The rugged sealed box was designed specifically for the subwoofer, so you can count on maximum performance whatever music you listen to.

• "3/4"" medium-density fiberboard construction covered with carpet"
• frequency response: 25-150 Hz
