Key features
- 6.5-inch 2-way coaxial design combines a woofer and 25 mm tweeter for marine audio installations.
- 125W RMS power handling and a 50 Hz-20 kHz frequency range support your onboard music system.
- Integrated RGB grille lighting adds color; the optional KTX-MRN-LED-RF controller is sold separately.
- A single waterproof 6-pin plug combines speaker and RGB LED connections for organized wiring.
- Black finish; IP66 splash/spray protection requires vertical exposed mounting and a protected rear.
Mount and connect for marine use
For exposed installations, mount vertically above the typical waterline on a flat surface that seals properly. Use the 6-pin plug for both audio and lighting; the gold-plated spades are parallel backup connections and can remain unused. Confirm clearance before cutting.
