About the Kicker 48CWRT84

Big sound from a small sub

If you're looking for bass for a tight space, Kicker designed their CompRT subs with compact cars, pickup trucks, and ATVs in mind. The low-profile 48CWRT84 8" subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub stands less than 3" tall, so your installation options are wide open. Kicker has redesigned the forced-air cooling system, so this sub will run cooler when you drive it hard (and you know you will).

Made to bring the boom

The 48CWRT84 comes equipped with a rigid injection-molded polypropylene cone that won't flex and cause distortion while you're cranking the bass. Its rubber surround will last through years of heavy use, combining with a special-design back and top plate to give you more excursion (which equals more bass) than other skinny subs.   

Made to fit many systems

This sub handles up to 300 watts RMS so make sure you've got a solid amp to power it. You can wire the dual voice coils for either 2- or 8-ohm total impedance, giving you more wiring options when setting up your system. This versatile sub sounds great in sealed or ported enclosures.

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.

Shallow-Mount: Kicker's CompRT series is designed to minimize depth, giving you subwoofer options where standard enclosures don't fit.

All-Weather: Although not marine certified, Kicker describes the CompRT series as weatherproof.

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 20% 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 0.2 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 the following ported enclosures:

  • 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 there a shallow mount 8" subwoofer at 2 ohms impedance? A 2 ohm SVC?
[ Von  Oct 18, 2021 ]

A
This subwoofer can be wired to present a 2 ohm impedance.
[ Paul  Oct 20, 2021 ]  Staff
Q
I noticed there is not an "ideal sealed box volume" in the specs, but a range of .2-1.0 cubic ft in the "Features" section? That seems like quite a wide range in air volume. I alsk because I'm looking for something to complement the Fender sub in my 2021 Nissan Titan CC and am trying to have it placed behind the rear seat. Thank you.

I purchased this sub to replace the oem in my Tacoma that sits behind the rear seat and the improvement in bass is noticeable. I'm not sure about the specs for my oem sub enclosure though. If you have an oem sub box I'm sure it's not gonna be much bigger or smaller than the one in my Tacoma.

Is this a plug and play ready sub for 2009 Jeep Wrangler Unlimited that has a factory sub?
[ Steve  Jul 28, 2021 ]

I swapped this for the factory sub in F-150 2006, and kept the factory amp. Very easy to connect.

[ RAVELLA  Jun 07, 2021 ]

[ Alex  Jun 07, 2021 ]
Q
I have a 2002 Chevy suburban w a 8" factory sub in back. This will fit but will it require an amplifier to work? If so, what size amp is needed?
[ Mike  Mar 30, 2021 ]
4 answers
A
No the factory amp well wrk just fine no need to change it
[ STEVEN  Mar 31, 2021 ]
A
I just installed this same amp in my Scion XB, and I'm running a 1 channel 500 watt amp. The minimum is 300 watt, but like to adjust my frequencies depending on my genre of music for the power so I like a little more ump with my bump.
[ REGINALD  Mar 31, 2021 ]
A
I would measure what the ohms are on the factory sub. I purchased the 2 ohm DVC's and the 4 ohm DVC's. The 2 ohm DVC's measured at 1 ohm per coil and the 4 ohm DVC's measured at 2 ohms. I currently returned the 2 ohm model and swapped them for the 4 ohm model. I have one installed in the factory box until my dual box comes. I am pushing with a Alpine 600 watt rms Amp. I tried running mine off the factory Amp and it wasn't enough power.
[ MARC D  Mar 31, 2021 ]
A
It should fit but would suggest a 300 watt amp
