About the Kicker 48CWR84

Bob Bihlmayer

Play maker

Kicker designed their CompR subs for people who love to hear powerful low-frequency punch in their music. The CompR 48CWR84 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 4-ohm voice coils make it easy to get maximum power from a mono amplifier, or to wire it into a multi-sub setup. This versatile sub works well in sealed or ported enclosures.

Product Research

Features

Dual Voice Coils: This woofer features dual 4Ω voice coils, offering wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When the voice coils are wired in series, the woofer presents an 8Ω 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

Q
Is this a good replacement in a 2023 Bronco using the factory amp and sub amp?
daniel r.  Mar 25, 2024
1 answer
A
Hey Daniel, so we do not have updated information in our system at this time to confirm the factory sub locations measurements to cross reference with any aftermarket sub. Typically when it comes to aftermarket subs though being ran on factory amps, there tends to not be enough power to push the sub properly anyhow and we would typically advise adding an amp as well to that location to drive a sub.

Q
If I want to run 4 of these what size amp should I get?
landon  Mar 10, 2024
1 answer
A
Hey Landon, great question. So if you were going to run four of those, we would need to find something that can get us 1200w RMS at 2-ohm since that is how the subs should be configured in this combination. Kicker actually makes a perfect match for that found here: https://www.crutchfield.com/I-rET1c402/p_20646CX12T/Kicker-46CXA1200-1T.html?tp=35834

Q
Will these work with a factory 2 ohm amp? It's the JBL premium sound system in a 2007 tundra
shawn  Feb 29, 2024
1 answer
A
This Kicker 48CWR84 is not a physical fit in your 2007 Tundra's factory JBL subwoofer location, Shawn. Your original JBL subwoofer is a single coil, 2-ohm speaker. You can install the Rockford Fosgate P3SD4-8 in the link below by re-drilling your mounting screw holes on the factory enclosure. This subwoofer can be wired to 2-ohms and use the factory amp, but for the best performance and sound quality an external aftermarket amp is advised. https://www.crutchfield.com/p_575P3SD48/Rockford-Fosgate-P3SD4-8.html

Q
Do I need to upgrade the factory Amp that is in my 2016 expedition?
joe  Dec 12, 2022
1 answer
A
That is a great question, Joe. For the best possible performance on the factory amp, use this dual 2-ohm version of the Kicker CompR 8" in the link below. This most closely matches the impedance of your original sub and would have the closest performance on the original amp. For best performance of any aftermarket sub we do Advise using an amp. The Alpine Power Pack Mono in the second link below is a great call to power any upgraded sub in a factory enclosure. https://www.crutchfield.com/p_20648CR82/Kicker-48CWR82.html https://www.crutchfield.com/p_500KTA200M/Alpine-KTA-200M-Power-Pack.html

Q
How can I get this to fit a 2019 Grand Caravan GT...its only 1/8" too deep for mounting depth. Is there anything that can be done like get a 1/8" thin custom trim ring between the sub and enclosure the gain that little bit of clearance?
