About the Kicker 48CWRT674

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 48CWRT674 6-3/4” subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub is less than 3" deep, 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 48CWRT674 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 150 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 works best in sealed 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.

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: Kicker recommends the CWRT67 be mounted in a sealed enclosure, between 0.18 ft³ and 0.75 ft³. Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music.

Customer Q&A

5 questions already asked

Q
Would this sub work okay with 40watts RMS to both voice coils?
[ Shawn D.  Nov 22, 2021 ]
1 answer
A
That would meet the minimum RMS watts that Kicker recommends and can work!
[ Paul  Nov 29, 2021 ]  Staff
Q
What size speaker wire to use on the 48cwrt674 12awg,10awg?
[ Reynaldo  Jul 29, 2021 ]
2 answers
A
12 was enough for mine.
[ Kenneth R,  Jul 29, 2021 ]
A
14AWG is fine, anything larger is overkill
[ MARK  Jul 29, 2021 ]
Q
Will these fit in the rear doors of a 2019 Hyundai Sonata ?
[ Mike  Jul 13, 2021 ]

In my opinion, if it's a 6 3/4 shallow mount hole, then I would think so. You'll need an aftermarket amp to make it work.
[ Chuck  Jul 13, 2021 ]
Q
If I hooked it up to the factory plugs in my 2012 Jeep jk roll bar would it work? Iâ??m trying to keep it mostly stock with some nice bass.

Joeingo, if you do power these properly, let me know how they turn out, I may try and pull something off with my roll bar as well, but in a TJ vs. a JK. I'd have to modify it a bit more to add something on the mid/high level, but that's nothing with some medical shears for the cover and a Dremel for the plastic in the soundbar.
[ Justus P.  Jun 04, 2021 ]
A
I would power these with an aftermarket amp with dedicated speaker wire. I have a bridged jl amp pushing mine and they sound amazing for such a small sub.
[ DANIEL  May 11, 2021 ]
A
I tried this actually.. I used a aftermarket head unit and they were significantly underpowered. It will work but my kicker 6.75 speakers produced more bass. Once I paired the subs with a appropriate amp they were amazing and loud, but door vibrations will need to be addressed.
