Description

The Kicker 8 CompRT (4‑Ohm) is an ultra-thin, all-weather subwoofer engineered for tight installs — under seats, behind benches, or in compact enclosures. Despite its shallow profile, it delivers solid bass, thanks to its dual 4‑ohm voice coil design, advanced cooling, and rugged construction. 

Key Benefits

  • Dual 4‑Ohm Voice Coils: Provides flexible wiring options for different amplifier setups. 
  • Forced-Air Cooling: Helps dissipate heat and improves reliability under load. 
  • Durable Construction: UV-resistant cone and surround make it suitable for outdoor or marine environments. 
  • SoloKon® Technology: The cone is joined to a vented back brace to reduce distortion and improve thermal handling. 
  • Flexible Enclosure Use: Works well in both sealed and ported boxes.

Installation & Compatibility

Amplifier Matching: Pair with an amp that provides around 300 W RMS for optimal performance.

Wiring Options: Due to its dual 4‑ohm coils, you can wire for 2 Ω or 1 Ω depending on your amp’s stability.

Mount Carefully: Make sure there is enough clearance for the 2‑11/16″ depth, especially behind seats or in tight boxes.

Cooling & Ventilation: Even though it’s low-profile, ensure some airflow around the sub to take advantage of its cooling features.

Use Case: Great for under-seat installations, compact trunks, or when you need fat bass from a small form factor.
