The new CompRT® Subwoofer Enclosures make surprisingly strong, smooth bass in a box under seven inches deep.

The CompRT 6-3/4-inch Subwoofer Enclosure is the easiest way to get great bass under your seat, behind your backbench, or in your cargo area. It comes loaded with a reFLEX™ passive subwoofer and CompRT active sub for extremely low bass, then carpeted and loaded with a single 2-Ohm terminal.

Built for extreme bass, this KICKER® sub-box has extensive internal bracing, thick MDF construction, and custom embroidery. The CompRT’s signature red double stitching makes an outstanding bond between the improved Santoprene surround and polypropylene woofer cone. Revolutionary SoloKon™ technology joins the cone to the vented back brace, creating a single integrated unit that both cools the motor and eliminates distortion.

To make their subs even more reliable, KICKER engineers developed Forced-Air Cooling™ to help their subs run 20 percent cooler than before. The CompRT 6-3/4-inch Subwoofer Enclosure works best with 150 watts of recommended power.

Use The Air

Heat is the enemy of endurance. To make their subs even more reliable, KICKER engineers developed Forced-Air Cooling to help their CompRT subs run 20 percent cooler.

Great Reflexes

KICKER's engineers added a Reflex Subwoofer to their CompRT loaded enclosures, giving you even deeper, smoother bass in an incredibly thin box.

It Fits

Whether it’s behind the backbench of your pickup, under a seat, or in the trunk, the CompRT sub box is a perfect fit. One amplifier connection later – you’re booming!

Built Tough

KICKER builds their boxes as tough as Oklahoma. A thick black carpet covers a box made with thick wood and internal bracing for excellent durability.
