About the Kicker 51MSC65
From our tech experts at CEN
Marine-grade 6.5 inch speakers handling 100w RMS, with UV-stable cones and corrosion-resistant hardware so they survive sun, salt and damp.
Who it suits
Boats, ribs and open vehicles, plus campers and outdoor builds where speakers live in the weather. Worth considering for any open-topped vehicle that sits outside.
Our tech experts advise
Marine installs live or die on the wiring: corrosion protection at every joint and a properly fused feed. Mounting location does more for the sound than the speaker choice. get in touch and we will talk through the layout. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Are the Kicker MSC65 speakers waterproof?
A: They are IP66 certified and meet or exceed ASTM standards for UV and salt/fog exposure, with corrosion-resistant waterproof connectors and 316L stainless mounting hardware.
Q: Do the MSC65 speakers have lights?
A: Yes. Integrated RGBW LED lighting is standard, letting you choose from a wide range of colours.
Q: Which grille colours come with the Kicker 51MSC65?
A: Both white and charcoal grilles are included in the box.
