Kicker 49KKPDF212 Kickpack 12 Inches CompSeries Subwoofer in Truck Enclosure/ D-Series 2-Channel Amplifier/ Wiring Kit

Enlarge your horizons with bigger bass

Kicker’s TRTP122 loaded enclosure puts a low-profile CompRT 12″ subwoofer and a 12″ passive radiator in a downward-firing box that brings Kicker bass power to the crowded spaces of today’s cars and trucks. The rugged sealed box was designed specifically for the subwoofer, so you can count on getting maximum performance, whatever you listen to. The second sub (called a “passive radiator”) reacts to the air pressure produced by the active sub, reinforcing the low end without the noise of a ported enclosure.
