About the Kicker 48CWR82
Play maker
Play maker
Kicker designed their CompR subs for people who love to hear powerful low-frequency punch in their music. The CompR 48CWR82 8” subwoofer comes equipped with a tough polypropylene cone that stays rigid during intense play sessions so you hear accurate bass. A custom-designed back and top plate give the woofer plenty of room to travel, while the double-stitched Santoprene rubber surround helps to control cone movement during a heavy workout. This sub uses newly designed venting in its heavy steel basket to shrug off heat, so you can count on reliable performance.
Any way you want it
This Kicker CompR sub will handle up to 300 watts RMS so make sure you have an amplifier that'll do it justice. Its dual 2-ohm voice coils give you more wiring options when setting up your system, and this versatile sub works well in sealed or ported enclosures.

Features
Dual Voice Coils: This woofer features dual 2Ω voice coils, offering wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 1Ω load. When the voice coils are wired in series, the woofer presents a 4Ω load.
Cooling: Kicker engineers developed a Forced Air Cooling system, using the motor structure to pull air across the voice coils, helping the sub run up to 25% cooler than the previous model.
Sealed Enclosures: Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music. Kicker recommends sealed enclosures from 0.4 ft³ to 1.0 ft³.
Vented Enclosures: Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from a given amount of power. Kicker recommends ported enclosures in the following range:
- Minimum Enclosure Volume: 0.8 ft³ with an 8" x 1½" x 20¾" slot port
- Maximum Enclosure Volume: 1.2 ft³ with an 8" x 2" x 19⅛" slot port
The Kicker 48CWR82 replaces these items
- injection-moulded polypropylene cone with rubber surround
- power range: 100-300 watts RMS
- frequency response: 30-500 Hz

Wow, this speaker is great. It is about 1" to deep for the box in the 2002 Yukon XL I mounted it in. It was relatively easy to use cardboard packing material some duct tape to build up the depth of the box and then install the speaker. It sounds great.
