JL Audio MVi 600 is a compact marine-rated monoblock Class-D amplifier with integrated digital signal processing (DSP), purpose-built to drive a dedicated subwoofer channel in high-output marine and powersports systems. Its DSP platform allows installers to configure crossover alignment, EQ, and level structure through JL Audio’s TüN™ software for controlled, low-frequency performance.
