Free Air Marine Bass Performance: The KICKER 45KMF104 is engineered for free-air applications, delivering 175-Watts RMS and 350-Watts peak without requiring a traditional enclosure. With a 4-Ohm voice coil and 30 Hz - 500 Hz frequency response, it provides deep low-frequency output tailored for marine audio systems where space and airflow configurations vary.
Marine-Grade Construction: Designed to handle harsh conditions, the 45KMF104 features an injection-molded polypropylene cone, co-molded Santoprene surround, polymer basket that resists corrosion, and protective terminal cap. Stainless mounting hardware and rear gasketing are included, and the sub meets or exceeds ASTM standards for UV and salt/fog exposure.
Optimized Motor And Fitment Specs: A UniPlate back plate and pole piece, thick tinsel leads, and a large ceramic magnet support consistent performance. Installation dimensions include 5 in mounting depth, 9.19 in hole diameter, and 10.69 in outer diameter, helping you plan cutout space accurately for bulkheads and marine panels.
Portable Party And Karaoke Sound: The RPB-KAR portable Bluetooth speaker includes a karaoke microphone and party LEDs for interactive entertainment. Use it as a house party speaker or bring it aboard for dockside gatherings, giving you wireless audio playback and vocal fun separate from your installed marine subwoofer system.
