8" CompRT 2 Ohm

The Kicker 48CWRT82 (also known in some versions as 40CWRT82 or 43CWRT82) is a slim-profile, 8″ subwoofer from the CompRT series. Designed for tight spaces like under seats or in rear cargo areas, it's built to deliver solid bass with a small footprint, thanks to its shallow mounting depth and rugged design.

Key Benefits

• Dual 2‑Ohm Voice Coils: Allows wiring flexibility (series or parallel) depending on your amplifier setup. 
• Thin Profile: Mounting depth of only ~2‑11/16″ (≈ 6.7 cm), making it ideal for tight installation spaces. 
• All‑Weather Durability: UV-resistant polypropylene cone and Santoprene surround give it resilience even in exposed conditions. 
• Forced‑Air Cooling: Helps the voice coil cool better under load, improving reliability. 
• SoloKon™ Technology: The cone is integrated with a vented back brace, reducing distortion and improving heat handling. 
• Power Handling: 300 W RMS and 600 W peak, giving a good power range for both compact amps and more powerful systems. 
• Flexible Enclosure Compatibility: Works well in both sealed and vented boxes.

Installation & Compatibility

Amplifier Matching: Recommend an amp ~300 W RMS for best performance.

Wiring Tip: Because it has dual 2‑Ω voice coils, you can wire:

In parallel → 1 Ω total

In series → 4 Ω total

Enclosure Options:

Sealed box: gives tighter, more controlled bass.

Ported box: offers more low-end output if properly tuned.

Mounting Constraints: Low profile allows installation where deeper subwoofers wouldn’t fit, but ensure you still have airflow for cooling.
