Kicker 46CWTB82 8" Weather-Proof Subwoofer

Whatever kind of music you like, you need a good subwoofer to make it sound great. When you also need to keep your cargo space, you need a powerful, compact solution. Kicker's 46CWTB82 tube subwoofer gives you window-rattling bass and impressive power handling in a surprisingly small package. The enclosure includes a 8" subwoofer and a second passive sub (called a "passive radiator") which reacts to the air pressure produced by the active sub, creating lots more bass without any port noise.

8" Bass Cannon

Kicker built the 46CWTB82 tube-shaped enclosure out of tough ABS plastic that'll stand up to the stresses of car life. The tubular shape pushes bass frequencies into the air like a cannon, pumping deep, resonant sound into your vehicle and your ears. You can mount the enclosure vertically or horizontally, letting it tuck neatly into a corner of your trunk or cargo area. Spring-loaded wiring terminals make it easy to connect the wiring from your amp.

Kicker Speaker Quality

You need a high-quality speaker to maximize the sound and impact of your music, and Kicker loads this enclosure with a 8" CompR sub that's ready to step up and bring the boom. Its polypropylene cone and Santoprene rubber surround maintain their shape to give you the serious bass you expect from Kicker. The speaker handles up to 300 watts RMS so you're sure to get the impact you want, while its 2-ohm impedance gets max power from your mono amp. The package includes mounting hardware and brackets for easy installation.

Overview: The Kicker CWTB82 is an 8" weather-proof passive subwoofer featuring a CompR driver and a passive Reflex woofer designed to be installed on Jeeps, boats, and UTVs. The 2 ohm subwoofer can handle 300 watts RMS and can be mounted either vertically or horizontally.

Enclosure: The CWTB82 is housed in a thick ABS enclosure with heavy-duty grills for a weather-proof subwoofer solution that's at home in the outdoors. Connection to the sub is done with two recessed spring-loaded terminals, providing a positive electrical connection while being protected from the elements. The sub also includes all hardware for mounting it either vertically, with 13-7/16" of mounting height, or horizontally, with 8-5/8" of height.

CompR: The Kicker sub enclosure includes a CompR mounted on one end and  a passive Reflex Subwoofer on the other end. The CompR features a powerful ceramic magnet, an advanced suspension, and superior heat management for long life. Kicker uses its signature red stitching on the woofer for an outstanding bond between the driver's Santoprene surround and Polypropylene cone, providing reliable performance under extreme conditions. Kicker's SoloKon technology joins the cone to the vented back brace, both cooling the motor and eliminating distortion, for clean smooth bass. The built-in Reflex Subwoofer uses the same cone and surround materials as the active sub and is mounted on the opposite end, providing even deeper louder bass than with just the active driver.
