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.
Rated for approximately 600 watts total system output, the MVi 600 delivers 400W x 1 into 4Ω or 600W x 1 into 2Ω, with a sub-focused 12Hz–500Hz bandwidth. IPX2 water protection and corrosion-resistant hardware ensure reliability in real marine environments, while its compact form factor supports multi-amp architectures in OEM-plus 12-volt builds.
