Bass has never been this loud and deep in a box this thin.
Using revolutionary ReFLEX™ subwoofer technology and
advanced enclosure construction, KICKER has developed the perfect box for fitting behind or under your seat.
CompRT Enclosures sport an extremely thin profile, and include heavy internal bracing for exceptional rigidity and ReFLEX™ passive sub technology for extending the low-end response.
KICKER has added Forced-Air Cooling that contributes to the woofer’s efficiency and durability, allowing the subwoofer to run more than 20 percent cooler. The subwoofers now feature a
sleek, blacked-out look with KICKER’s signature red stitching
on the cone.
The refined look of CompRT Enclosures include a custom embroidered
KICKER logo, all black carpeting and satin-nickel
terminals. CompRT enclosures come in an array of sizes, ranging
from the mighty-mite 6-3/4-inch TCWRT67 to the big-boss
12-inch TCWRT12 in a 2-Ohm load. Mount them behind your
seat, or even under it!

Kicker's CWRT122 loaded enclosure puts a low-profile 12" CompRT subwoofer and a second passive sub 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 music 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.

The 12" CompRT sub's tough injection-molded polypropylene cone gives it the stiffness to resist distortion when you're pushing the volume. Its rubber surround stands up to heavy use, and combines with a specially-designed back plate to give you more excursion (which equals more bass) than other skinny subs. This sub handles up to 500 watts RMS, so you'll get the kind of bass response that brings the best out of your music.

The box's downward-firing design helps protect the sub from damage, and lets you place items on top of the cabinet to save space. Its sturdy medium-density fiberboard construction and rugged black carpet covering give the enclosure good looks that complement its performance.
