Compact Acoustic Performance

The Kicker 48CWRT84 is an elite 8" thin-mount transducer from the CompRT series, meticulously engineered to deliver a rich, foundational bass response in environments where traditional drivers cannot fit. With a mounting depth of less than three inches, it is the ideal solution for under-seat enclosures in compact vehicles or behind the bench in pickup trucks. This all-weather driver features a blacked-out SoloKon polypropylene cone and a UV-resistant Santoprene surround with signature red double stitching, ensuring it maintains its acoustic integrity even in the rigorous conditions of off-road or marine installations.

To ensure consistent performance during high-output sessions, the 48CWRT84 incorporates Kicker’s Forced-Air Cooling, which allows the motor to operate significantly cooler than standard slim-line designs. By utilizing the movement of the cone to cycle air through the assembly, this system preserves signal clarity and protects the internal voice coils from thermal fatigue. With its Dual 4-Ohm Voice Coil (DVC) configuration, this 8" driver provides the system-building flexibility required to achieve a precise impedance match with high-performance mono-channel amplifiers.

Excellent Value

The following review is for a previous version (40CWRT82).

I purchased the Kicker 40CTWRT82 (Comp82) 8" subwoofer to replace the stock sub that's in my 1998 Lexus ES300. Should the overall sound quality (Bass) be as great as the purchase/service (Kyle ext 2555) I will have a smile from ear to ear as a satisfied customer. Thank you Sonic Electronix.

Very good sub

The following review is for a previous version (40CWRT82).

This was a replacement for the stock sub that came with my 2002 Suburban. It fit in the factory housing without issue, using sheetrock screws as the factory holes were not an exact match. It was a shallow mount which was what was required, but it doesn't skimp on sound.

The sound (or air movement) is great for an 8 inch, and is more than adequate for anyone not wanting to DJ parties from their car.

I would recommend to anyone in the market for an 8 inch sub.
