The sixties are over, dude! "Very Radical" now means great bass, courtesy of Kicker's CompVR subwoofers. The 01C8VR2 8" woofer gets down low, thanks to its powerful, flex-resistant poly cone and rigid, non-resonant steel basket. Dual 2-ohm voice coil construction provides extra flexibility in wiring up your system.

Combine a beefed-up suspension with Kicker's Perimeter Venting, and you've got a sub that'll run cool and sound hot. The Santoprene rubber surround minimizes cone distortion and resists the elements. These subs take everything you give them and throw it back, deep and punchy. (Kicker's distinctive cast-aluminum grilles are available separately.)

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Features

Dual Voice Coils: For increased system flexibility, this woofer has two 2 ohm voice coils. When the voice coils are wired in parallel with each other, the woofer presents a 1 ohm mono load. When the voice coils are wired in series with each other, the woofer presents a 4 ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 2 ohm load.

Cone Materials: The cone is constructed of mica-filled polypropylene. Mica adds strength and heat resistance to polypropylene; the result is reduced distortion and improved reliability. In addition, the cone is also very resistant to environmental extremes.

Surround: This subwoofer uses a tough, flexible, highly tear-resistant santoprene rubber surround. The surround is double-stitched to the cone edge, making separation between them virtually impossible.

Inverted Structural Dome: The Inverted Structural Dome replaces a conventional dustcap and locks into the cone for unmatched structural integrity and greatly reduced cone flexing/resonance.

Voice Coils: The ultra-length voice coils allow enormous cone excursion for incredible deep bass.

Voice Coil Former: The hi-temp Kapton voice coil former protects against warped, rubbing voice coils.

Extended Pole Piece: The extended pole piece creates a broad, symmetrical magnetic field for superior power handling, precise voice coil control, and very low deep bass distortion. Venting in the pole piece eliminates noise and distortion caused by huge amounts of airflow created by cone excursion.

UniPlate Construction: The UniPlate construction combines the backplate and extended pole piece into a single unit to maximize magnetic efficiency and minimize alignment problems often caused by two-piece construction.

Black Plating: The black plating on the UniPlate and front plate provides maximum heat dissipation for cool operation and extended voice coil life.

Bumped Back Plate: The deep bumped back plate lets the voice coil reach maximum excursion without bottoming-out.

Perimeter Venting: The perimeter venting cooling system continuously pumps hot air away from the voice coils, replacing it with cool outside air.

Gasket: A rubber gasket insures an airtight seal.

Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet during installation.

Spring Posts: The nickel-plated spring posts will accept bare wire and pin connectors.

Enclosure Compatibility: This woofer can provide extended bass in sealed and vented enclosures (please see the "Specifications" section for more information on the recommended enclosures).

Specifications

Power Handling: When the subwoofer is mounted in a sealed enclosure that has a volume of 0.4 cu/ft, each coil can handle up to 100 watts RMS (200 watts peak). In a 1.8 cu/ft sealed enclosure, each coil can handle up to 50 watts RMS (100 watts peak). Generally, when the woofer is mounted in a vented enclosure, its power handling decreases depending on the size of the enclosure. In a 0.8 cu/ft vented enclosure, each coil can handle up to 37.5 watts RMS (75 watts peak). In a 1.2 cu/ft vented enclosure, each coil can handle up to 60 watts RMS (120 watts peak).

Recommended Sealed Box Volume: The recommended sealed enclosures have the highest power handling capability of all the recommended enclosures. When mounted in a sealed enclosure, the woofer delivers smooth bass response with good low bass extension.

  • Compact (minimum enclosure volume): 0.4 cu/ft; each coil can handle up to 100 watts RMS (200 watts peak)
  • SQ (maximum enclosure volume): 1.8 cu/ft; each coil can handle up to 50 watts RMS (100 watts peak)

Recommended Vented Box Volume: The vented enclosures incorporate massive slot-loaded ports with ultra- low air velocity and hard-hitting bass. These are not your traditional port tubes; the slot-loaded ports are integrated into the enclosure design.

  • Compact (minimum enclosure volume): 0.8 cu/ft; 1.5"x8" port opening; 20" port depth; each coil can handle up to 37.5 watts RMS (75 watts peak)
  • SQ (maximum enclosure volume): 1.2 cu/ft; 2"x8" port opening; 18.375" port depth; each coil can handle up to 60 watts RMS (120 watts peak)

Manual Corrections

Manual Corrections: The specifications printed in the February 2001 manual are preliminary. Per Kicker, some of the specifications have changed and the following is a list of corrections:

  • SPL: The manual lists the sensitivity as 83dB. The correct sensitivity is 82.8dB.
  • Vas: The manual lists the Vas as 16.7 liters. The correct Vas is 16.73 liters.
