The only thing thin about the CompRT® Subwoofer is the mounting depth. Whether it’s on the road, sand or trail, these tough subs work perfectly in nearly anything with a motor.

Heat is the enemy of endurance. To make our subs even more reliable, KICKER engineers developed Forced-Air Cooling to help our CompR subs run 25 percent cooler.

8" CompRT 4 Ohm
The CompRT 8-inch Subwoofer is an all-weather thin subwoofer with a pair of 4-Ohm voice coils. With a mounting depth under three inches and plenty of power handling, this go-anywhere sub is as flexible as it is powerful. A UV-resistant cone and surround help make the CompRT sound great wherever the road (or trail) takes you.
An advanced suspension and heat management system helps to keep the bass powerful, deep and consistent. To make our subs even more reliable, KICKER engineers developed Forced-Air Cooling™ to help our subs run 20 percent cooler than before.
Our 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.
The CompRT 8-inch Subwoofer works best with a sealed enclosure and 300 watts of recommended power. See below for more details.
