KM Marine 150W 2 Channel Class A/B Full-Range Amplifier
48KMA1502
A marine-grade 2-channel amplifier built to handle the harsh conditions on the water, without sacrificing sound quality.
Running on Class A/B power, the 48KMA1502 delivers clean, reliable output across two channels with bridging capability for added flexibility. The built-in KickEQ™ variable bass boost adds up to 12dB of extra low-end, while the variable 12dB crossover lets you tune your system to suit your setup.
Every component is chosen with marine use in mind. The conformal-coated circuit board resists moisture and corrosion. ABYC/NMMA-compliant power connections meet marine safety standards, and 316L stainless-steel hardware is included to prevent rust in wet environments.

About the Kicker 48KMA1502
From our tech experts at CEN
A marine-rated amplifier, 2 channel, rated at 150w RMS, coated to cope with damp and salt air where a car amplifier would corrode.
Who it suits
Boats, ribs and open builds, and anywhere an amplifier is mounted somewhere it will get damp. Campers with outdoor speakers are an increasingly common use.
Our tech experts advise
Mount it somewhere ventilated and as dry as the boat allows, and fuse the feed at the battery. Marine wiring wants tinned cable and sealed joints. get in touch to talk through the install. See car audio installation.

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.
