More about the product

The Kicker 48KMA360.4 is a marine-grade four-channel amplifier designed to deliver clear, dynamic sound in harsh outdoor environments. Built for boats and watercraft, this amplifier combines rugged durability with high-performance audio. It provides up to 500 watts of dynamic power, ensuring strong output for multiple speakers while maintaining clarity and efficiency.

This model uses a Class A/B design, which offers smooth, detailed sound reproduction. The amplifier includes bridging capability, allowing flexible configurations for different marine audio setups. Its conformal-coated circuit board protects against moisture and corrosion, making it ideal for saltwater conditions. Real Marine™ ABYC/NMMA-compliant power connections ensure safe and reliable installation that meets marine standards.

The Kicker 48KMA360.4 features a variable 12dB crossover for precise tuning, giving users control over how frequencies are distributed across speakers. It also includes KickEQ™ technology with a variable 6dB bass boost, allowing extra low-end punch when needed. These tuning options make it easy to optimise sound for different environments and music styles.

Designed for durability, the amplifier uses corrosion-resistant materials and stainless-steel hardware. Its compact footprint makes installation straightforward, even in tight spaces. The amplifier is engineered to withstand vibration, temperature changes, and exposure to water, ensuring consistent performance during extended use.

While the Kicker 48KMA360.4 offers excellent sound quality and marine protection, it is best suited for mid-range systems rather than extreme high-power setups. It provides enough output for most marine environments but may not satisfy those seeking maximum volume for large boats with multiple zones. For everyday marine audio needs, it strikes a balance between power, reliability, and ease of installation.

Overall, the Kicker 48KMA360.4 is a dependable choice for anyone looking to upgrade a marine audio system with strong, clean sound and proven weather resistance. Its combination of Class A/B performance, flexible tuning, and marine-grade construction makes it a standout option for boating enthusiasts.
