KXM Marine 500W 4 Channel Class D Full-Range Amplifier
48KXMA5004
KXMA Amps are built for the outdoors. Gain, crossover and bass-boost controls are protected behind a gasket-sealed panel, as is the control cover hiding the settings, creating a water-resistant barrier to key controls.
The KICKER Real Marine standard means your amplifier is purpose-built for your boat. Every KXMA (and KMA)-Series amp comes complete with anti-corrosive speaker, power and RCA terminals, stainless-steel screws, conformal-coated circuit boards and ABYC/NMMA-compliant power connections. KICKER products also undergo rigorous testing to ensure they meet or exceed marine industry standards for UV, humidity and saltwater exposure. This unparalleled commitment to engineering quality and maritime safety is why our products truly are "Real Marine."
KickEQ™ delivers as much as an 6dB of extra bump with a simple turn of the knob. A powerful 24dB crossover is also included, letting you quickly tune your system to perfection. A full-range RCA output allows you to easily add another amplifier without running new signal cable to your KICKER KMC Media Center.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
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.
