Compact enclosure, powerful bass

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.

Customer Q&A

Does this sub come with dual voice coils or a single? If dual, where is the other set of +,- terminals (I only see one on the outside in pics)?

Hey Greg, this is a single post wiring. The sub may potentially be a DVC but its already wired to a single set of posts at a 2-ohm impedance.

Product Research

Features

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.

Enclosure Type: Reflex
Driver: 8" CompR
Power (RMS/Peak): 300/600 Watts
Impedance: 2Ω
Sensitivity (dB 1w/1m): 84.4

Okay, so in that case treat as an SVC sub for wiring purposes? For example, I could wire 2 of the 4ohm version in parallel to achieve 2ohms total? (Wired to single channel providing 500w @ 2 ohm)

Is this speaker waterproof?

mark Apr 02, 2024

1 answer

This Kicker 46CWTB82 is weather-proof, Mark. While not being described as waterproof, the Kicker subwoofer is designed for install in locations where it could be subjected to humidity and moisture.

Is 350 RMS watts too much for this product?

josh Feb 23, 2022

1 answer

We recommend to not exceed the subwoofers RMS watts when matching an amp to a subwoofer. We have advisors that can be reached by calling 1-800-324-9695 who can give you a personal recommendation

jason Feb 26, 2022 (Staff)

Hi there, I'd like to mount this on a vertical surface using the horizontal mount. Do you think it's strong enough to hold? The mounting bracket seems like a strong plastic but has anyone done this?

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
