Low-Profile Acoustic Precision

The Kicker 48CWRT674 is a high-performance, ultra-slim 6.75" transducer engineered for the CompRT series. Designed specifically for installations where space is at a premium—such as under-seat enclosures or tight door panels—this driver delivers an authoritative bass response that defies its compact dimensions. By utilizing a blacked-out SoloKon polypropylene cone and an improved Santoprene surround with signature red double stitching, the 48CWRT674 maintains exceptional tonal accuracy and structural integrity even during high-excursion performance.

Thermal management is a critical feature of this thin-mount driver. It incorporates Kicker’s Forced-Air Cooling technology, allowing the subwoofer to operate 20% cooler by using the cone’s own motion to circulate air through the motor structure. With a mounting depth of less than three inches and a Dual 4-Ohm Voice Coil (DVC) configuration, this transducer offers the system-building flexibility required for sophisticated, space-saving high-fidelity installations.

Great factory replacement

The following review is for a previous version (40CWRT672).

Installed it in my 05 Wrangler with just a few mods and sounds great on the factory amp for what it is. Very pleased with my purchase!

These are dynamite.

They can’t move air like a 12”, but having two of these in my stock oem box made a huge difference. They kick butt and are louder and deeper than my stock Rockford fosgates.

Excellent Value

I would recommend these speakers to anyone.

Great OEM replacement

The following review is for a previous version (43CWRT672).

Used this in the factory center console location of my Wrangler TJ. Surprisingly punchy for a small subwoofer being powered by the OEM amplifier. Granted, there is only so much air to be moved by a 6.75" speaker, but it surpassed my expectations.

More bass then expected

The following review is for a previous version (43CWRT672).

This little speaker beats hard and sounds good. Would recommend for small spaces.

Kicker 6.75 subs

The following review is for a previous version (40CWRT672).

These thing kick serious butt! I didn't know what to expect due to there size, but me and the guys who hooked them up where all blown away. They are both audio guys who run much bigger systems and there looking at these things and shaking their heads in disbelief. Nice Job Kicker
